Street view, traffic lights, photography skills, teaching reflection, short
The following is a reflection on the teaching of street traffic light photography skills: ** 1. Perspective ** 1. ** Strengths ** - Low angle, high angle, close-up, and many other perspectives made it possible to shoot at traffic lights. A low angle could create a unique reflection, a high angle could show its position in the urban layout, and a close-up could capture the details. All of these could bring different visual effects to the work. - The teaching of multiple perspectives helped the photographer get rid of the limitations of a single perspective and show the common streetscape elements of traffic lights from different dimensions. 2. ** Not enough ** - There was little mention of the difficulty of switching perspectives in some special scenes. For example, at a busy intersection, there might be safety risks if you wanted to get a low-angle shot. Teaching should emphasize how to choose the right angle while ensuring safety. - The combination of different perspectives could be further deepened in teaching. For example, how to skillfully combine high angles and close-up perspectives in the same work to tell a richer story. ** 2. Light and shadow effects ** 1. ** Strengths ** - The emphasis on the lighting effect was crucial. Making good use of the golden moments in the morning and evening, different light directions, and color contrast could make the traffic lights stand out more in the picture and enhance the artistic sense of the work. - The teaching of light and shadow could guide the photographer to observe and use the most important element in photography, which would help to improve the overall quality of the work. 2. ** Not enough ** - In actual shooting, the complex changes in lighting under different weather and time conditions were not detailed enough. For example, how to create light and shadow effects on cloudy days, and how to adjust the shooting parameters in time when the light changed rapidly. - The interaction between light and the surrounding environment could be explained in more depth. For example, how the reflection of the buildings around the traffic lights affected the lighting effect and how to use it. ** 3. Humanistic Elements ** 1. ** Strengths ** - The teaching that incorporated cultural elements made the traffic light photography more warm. The concept of capturing the moment and finding the story made the photo not just a simple record of the traffic lights, but a portrait of the city life. - This kind of teaching would help the photographer improve the content of his work, from simple scenery photography to the scope of cultural documentary photography. 2. ** Not enough ** - There was no mention of the difficulty of capturing the human elements in some special situations or how to deal with them. For example, how to accurately capture the reaction of a representative character in a crowded place. - There was a lack of in-depth discussion on how to guide the character's performance in the scene to better interact with the traffic lights. ** 4. In terms of abstract expression techniques ** 1. ** Strengths ** - Exploring abstract expression techniques added creativity to the traffic light shooting. Techniques such as shadow games, reflection and refraction could make the work full of artistic sense and poetry. - This kind of teaching encouraged photographers to break through traditional thinking and try to express common street elements in different ways. 2. ** Not enough ** - Some of the technical difficulties of abstract expression techniques in actual operation were not fully explained. For example, how to avoid image distortion and stray light interference when using glass refraction. - There was not enough teaching about the integration of abstract techniques and other shooting techniques, such as how to combine abstract techniques with light and shadow effects to create more unique works.

The video teaching of photography street sweeping skills is simple
Here are some photography tips: ** 1. Equipment related ** 1. ** Focus selection ** - The focal lengths that were close to the human eye's perspective, such as 28mm, 35mm, and 50mm, could be used to sweep the streets, giving the audience a more realistic sense of immersion. Some people also used telephoto lenses (such as 70 - 200mm f/2.8) and wide-angle lenses (such as 17 - 35mm f/2.8), while others chose 24 - 105mm lenses, which were more applicable. 2. ** Familiar with the camera ** - Proficiency in camera operation was the most important. Although the automatic transmission of digital cameras performed well, he still had to familiarize himself with the functions of the camera. For example, he could determine a set of suitable parameters according to the light at different times and use the parameters to shoot until the light changed. This way, he could quickly press the shutter when he found something interesting without worrying about the camera settings. - The aperture was generally set between f/5.6 and f/11. Because in street photography, too large an aperture would make the depth of field shallow and easy to lose focus, especially when there were multiple focal points in the picture, and a large aperture would slow down the focusing speed. - In terms of shutter speed, a shutter speed of 1/500s could be used when there was sufficient sunlight, so that clear images could be captured even when shooting while moving. If the shutter speed was lower than 1/100s, the image needed to be completely still to ensure clarity. ** 2. Shooting content and subject ** 1. ** Respect the subject ** - They should avoid shooting people's faces, and they shouldn't specifically target the toiling masses. If you want to shoot people, you can pay more attention to the light and shadow, and take more pictures of their backs and silhouettes. 2. ** Capture the moment ** - Street photography was about capturing the beauty of the moment. It required sufficient insight and patience. It was possible to take many photos in one place and then choose from them. 3. ** Using Reflex ** - The reflective properties of objects such as surrounding glass, windows, mirrors, and water could be used to subtly blend the scene of the background, the background, and the reflective surface from different perspectives. When shooting, one had to have keen observation and creativity. He had to integrate interesting reflections into the overall composition, so that the picture would be multi-layered and multi-dimensional. It would integrate the originally unrelated elements in the three-dimensional space to form a strong visual impact. 4. ** Using silhouettes ** - Look for scenes with large light ratio, such as bright sky, luminous billboard, illuminated ground, elevator entrances, etc., using the high contrast between light color and shadow. You can use the "highlight" measuring mode to ensure that the light is not exposed. The image control can choose the high contrast black and white mode to increase the contrast of the picture, adjust the brightness in the middle, and make the silhouette more prominent. Focus on the places where the character may pass by. When the character walks to the highlight in the picture, the silhouette can be highlighted. You can also use the "continuous shooting mode" to capture the best moment of the character's movement. ** 3. Composition-related ** 1. ** See through relationships ** - In remote streets, the lines formed by the buildings on both sides of the street would converge to a point, reflecting the sense of space and the beauty of form. Using a wide-angle lens could make the perspective effect more obvious. Under the eaves of the flyovers or alleys, you can also use the perspective traction line. If the four lines converge towards the center and the environment is simple, the visual impact of the picture will be stronger. The convergence point has a distinct main picture and it will be more expressive. - In a busy city, a low-angle shot could highlight the beauty of the zebra crossing and other lines. Even if there were pedestrians, the scene would not be too messy. 2. ** Building Lines ** - There were many buildings on the street. When shooting, pay attention to the angle that can highlight the beauty of the architectural structure. When shooting, raise the camera slightly to avoid pedestrians. It could also capture the curves of the building and express its color. 3. ** Shooting from different angles ** - Upward shots of tall modern buildings can be taken to show their height. When there is fog, it can be taken to show the effect of towering into the clouds. However, it is not recommended to shoot from the sky around noon. When sweeping the streets, you should look up more often. You might take interesting pictures such as birdcages hanging on the streets. - Controlling the shooting range and retaining regular images, such as buildings, people, advertising boards, guardrails, etc., can highlight the sense of street form. - Try shooting from a low angle to create a visual impact, such as shooting people's footsteps in a crowd. ** 4. Others ** 1. ** Prepare the camera at any time ** - Cultivate good shooting habits and always have a camera ready. 2. ** Sweeping the streets alone ** - Try not to sweep the streets with your friends. Street photography is more suitable for personal sniping. 3. ** Blind Shooting Practice ** - Practice not looking at the viewfinder composition, practice blind shooting skills, because there are many times when there is no chance to look at the viewfinder or need to shoot secretly. 4. ** Daily Practice ** - The brain needed to be trained regularly to form muscle memory. It had to be practiced often. Even if it was only half an hour a day, it had to take more photos to avoid not taking photos for a long time, causing it to be at a loss when picking up the camera again. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

To guide children to abide by the rules of social behavior and not to do anything against the rules. 4. Arouse children's interest in exploring the variety and characteristics of life. ##2. Teaching preparation 1. Images of traffic light signs and projections of traffic signs observed by children in their daily lives. 2. A red, green, and yellow traffic light made of cardboard. ##3. Teaching process ###(1) Introduction of the topic 1. Show the traffic safety picture and lead to the topic of "obeying traffic safety rules." 2. Learn about the red, green, and yellow lights together with the child. Through the content of the children's song, let the child know "stop at the red light, go at the green light, stop at the yellow light". ###(2) Explanation of Game Rules and Game Development 1. The children were divided into two groups. One group acted as a small car, and the other group acted as a child walking. It was stipulated that cars and pedestrians must stop when they saw a red light and could only walk when they saw a green light. 2. During the game, the teacher should pay attention to guiding the children to obey the traffic rules. ###(3) Game summary and daily safety knowledge expansion 1. At the end of the game, the teacher and the child would make a summary together, praise and reward the child who abided by the rules, and ask the child to bring this knowledge home to share with his parents. 2. From the activities, other safety matters in daily life were introduced, such as eating slowly, watching the road when walking, and not walking with strangers. In addition, music games could also be used to teach about traffic lights: ##1. Game goal 1. In the traffic light game, try to use various forms to perceive and express the characteristics of the music of "start and stop". 2. Able to react quickly to changes in music. ##2. Game preparation Music and Red Bracers each had one. ##3. Game process ###(1) First Game 1. How to play: All the children sit in a circle and imitate the teacher driving the car with the music. When the music stops, they immediately stop moving. 2. Guiding points and key points: Through body movements, guide children to perceive and discover the characteristics of music that starts repeatedly and stops suddenly. ###(2) Second Game 1. How to play: Group driving with the change of the music. In the first half of the music, the teacher used "Red light, green light, red light immediately" to remind the group to sit to the right and change seats, step on the brakes, and ask to park the car well, otherwise they will be fined by the traffic police. 2. The main points and key points of the instructions: When the phrase stops, quickly react to shift to the right, brake, and control your body to stay still. ###(3) Third Game 1. Play method: collectively stand on the point of the circle in the counterclockwise direction, and do the twisting car action according to the change of the music. In the first half of the music, the teacher will use "red light green light, red light immediately" to remind the children to quickly react and move forward to brake (park their car in front of the parking space). At the end of the music, guide the children to make different parking poses and control their bodies. Otherwise, they would be fined by the traffic police uncle. 2. The key points of guidance: Quickly react and change positions to stop the car before the music stops. At the end of the music, you can make different poses and control your body. ###(4) The fourth game 1. How to play: Two children stand face to face on the points of the circle and drive the car according to the changes of the music. When they hear "red light, green light, red light immediately", the young driver quickly reacted and held his right hand to exchange parking spaces. Finally, when the music came to an end, he guided the child to stand on a chair and pose in a different parking pose. 2. The main points and key points of the instruction: Quickly react and change parking spaces in pairs before the music stops. At the end of the music, stand on the chair and pose differently to stabilize the body. ###(5) The fifth game 1. [How to play: Turn into a train and drive freely with the music.

The switching of car lights, how to write short teaching reflection
The following is a brief example of teaching reflection on switching car lights: ** I. Teaching Achievement ** 1. ** Knowledge Transfer ** - He had basically completed the explanation of the knowledge related to the switching of car lights, including the requirements for switching lights in different scenarios (such as driving at night, vehicle intersection, rainy and foggy weather). For example, students learned that high beam lights should be used at night when there were no street lights, and switched to low beam lights when there was a car coming from the opposite side, and that turn signals should be used correctly when the car turned. - Through theoretical explanations and simulations, most students were able to tell the timing of the switching of lights. 2. ** Skill Training ** - In the practical training session, some students could better grasp the operation of the car light switch and realize the correct switching of the lights. This showed that practical practice had a positive effect on students 'mastery of skills. ** 2. Inadequacies ** 1. ** Not enough attention to individual differences ** - During the teaching process, they did not take full care of the learning progress of all students. Some students were slow to get used to the switching of lights, but they did not receive enough individual guidance. 2. ** Real-world simulation limitations ** - Although a simulation was performed, there was still a gap between it and the real driving scene on the road. This might cause the students to make inaccurate judgments about the switching of lights in the actual driving scene. ** 3. Modification measures ** 1. ** Individual guidance ** - In the future, he would increase the time for individual tutoring for students with learning difficulties to ensure that every student could master the lighting switching skills. 2. ** Enhanced Scene Simulation ** - He further optimized the simulation scene and combined it with more actual road conditions, such as switching lights under complex road conditions, to improve the students 'ability to cope with different situations. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Teaching Design and Reflection of Changing Lights
The following is a summary of the teaching design and reflection on the switching of car lights: ##1. Teaching Design ###(1) Teaching objectives 1. knowledge objectives - Let the students understand the functions and uses of different lights (such as high beam lights, low beam lights, fog lights, width indicator lights, daytime running lights, etc.). - Master the operation method of switching between different lights. 2. skill target - Students can skillfully operate the car light lever and knob to switch the lights correctly. - Cultivate students 'ability to choose and switch lights correctly in different driving scenarios (such as meeting at night, driving without street lights, driving in foggy weather, etc.). 3. emotion goal - To raise the students 'awareness of safe driving and emphasize the importance of using lights correctly for their own safety and the safety of other road users. ###(2) Teaching content 1. The types and functions of car lights - High Beam: It is used to provide long-distance illumination on roads without street lights or poor lighting, but it needs to be switched correctly when passing cars to avoid affecting the driver's line of sight. - Low Beam Lamp: It is suitable to be used when there are cars or pedestrians in the opposite direction. It can ensure the illumination of the road while avoiding glare. - Fog lights: divided into front fog lights and rear fog lights, in foggy days and other low visibility conditions to improve the visibility of the vehicle. - Width-indicating light: used to display the width of the vehicle, used in scenes such as parking in the evening or at night. - Daytime running lights: Increase the visibility of vehicles during the day. 2. Operation method of switching lights - Light lever operation - Pushing it out was the high beam (usually used when there were no street lights); dialing it in was the low beam; dialing it in twice (continuous operation) was to remind the other party that the headlights were too dazzling; dialing it in three times in a row was to tell the car in front that there was a problem and that it needed to be stopped by the side for inspection. - Pulling it out once was the front fog light, pulling it twice was the rear fog light. - Light knob operation - Turning it to the STAR position meant automatic headlights, aiming at a specific symbol (such as the cat face symbol) meant width indicator lights, and aiming at the jellyfish symbol to the left meant low beam lights. ###(3) Teaching Method 1. theoretical explanation - Through pictures, videos, and other media resources, the students were shown the appearance of different lights and their locations on the vehicle, and the functions and application of various lights were explained. 2. simulation operation - In the driving simulator or the teaching aid vehicle with a light operation device, the students were allowed to practice the actual operation of switching the lights. The teacher was beside them to guide and correct them. 3. case analysis - List the cases of traffic accidents caused by improper use of lights (such as not switching the low beam lights at night), guide the students to analyze the causes of the accidents, and emphasize the importance of using lights correctly. ###(4) Teaching process 1. Introduction (5 minutes) - By playing a video of a dangerous situation caused by improper use of lights on the road at night, the students would pay attention to the correct use of car lights, which would lead to the theme of this lesson. 2. Knowledge explanation (15 minutes) - Using the multi-media class, the paper introduced the types, functions, and operation methods of the car lights in detail, including the light switch effects corresponding to the various operations of the light lever and knob. 3. Simulation Practice (20 minutes) - The students were divided into small groups and took turns to practice switching lights on the driving simulator or teaching aid vehicle. The teacher patrolled each group and corrected the students 'mistakes in time. 4. Case Analysis and Discussion (15 minutes) - Show a few typical traffic accidents caused by improper use of lights, organize the students to have a group discussion, analyze the problems in the use of lights in the accident, and propose the correct operation method. Each group sent a representative to speak, and the teacher summarized and supplemented. 5. Summing Up and Consolidating (5 minutes) - The teacher summarized the key points of this lesson and emphasized the importance of switching the car lights correctly for safe driving. - After class, the students were asked to practice switching lights on the actual car with their parents and record their feelings in different scenarios. ##2. Reflection and summary ###(I) Success 1. variety of methods - Through theoretical explanations, simulations, and case studies, the students were able to fully understand the knowledge and skills of switching car lights. The theoretical explanation laid a solid foundation for the students. The simulation operation allowed the students to experience the operation process of switching the lights. The case analysis closely linked the knowledge with the practical application and improved the students 'safety awareness. 2. Make full use of teaching resources - The rational use of teaching resources such as multi-media coursewares, driving simulator, and teaching aid vehicles enhanced the intuitive and interesting nature of teaching. Pictures, videos, and other multi-media resources could vividly display the types and functions of car lights. The driving simulator and teaching aid car provided students with a near-real operating environment, which helped students better master the operation skills of light switching. ###(2) Deficiency 1. Not enough attention is paid to the individual differences of students - In the simulation operation practice segment, due to the differences in students 'learning ability and proficiency, some students might not receive sufficient guidance and practice time. In future teaching, more attention should be paid to the individual differences of students, and more guidance and practice opportunities should be given to students with difficulty in operation. 2. The simulation of the actual scene is limited - Although the case analysis session allowed students to understand the correct use of lights in different scenarios, in the simulation practice, the simulation of some special scenarios (such as the use of light signals in emergency situations) was not sufficient. In the future, he could add more simulation exercises in special scenes to improve the students 'ability to use lights correctly in complex situations. ###(3) Enhancement measures 1. stratified teaching - According to the students 'learning ability and operation level, the students were divided into groups of different levels, and targeted teaching objectives and practice tasks were formulated for each group to ensure that each student could fully develop within their own abilities. 2. Rich simulation scene - Collect more cases of lighting usage in special scenes and incorporate them into simulation practice. For example, it could simulate the use of lights when driving on mountainous roads and curves, as well as the light signal when encountering emergencies (such as vehicle failure, road construction, etc.). At the same time, some role-playing elements could be added to let the students feel the importance of lighting in different scenes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on Street Interviewing Skills
Street interviewing techniques can be summarized as follows: 1. ** Preparing Work ** - ** Confirm the topic **: Confirm the core content of the interview. - [Prepare your speech and questions: Carefully prepare concise and clear questions in advance to avoid abstract and vague expressions.] At the same time, he had to prepare the opening remarks for the interview. - ** Understand the background of the interviewee (if possible)**: This will help you better interact with the interviewee and ask more targeted questions. - ** Choose suitable equipment and pay attention to clothing **: ensure that the interview equipment is complete and can work normally, and dress appropriately. 2. ** Choose related elements ** - ** Location Selection **: Choose a suitable interview location and pay attention to whether the environment is noisy or has interference. - ** Time Selection **: Choose a suitable interview time to avoid inconvenience to the interviewee. - ** Target Selection **: Confirm a suitable target for the interview. 3. ** During the interview ** - ** Building Trust **: Greet first, introduce yourself and the purpose of the interview, so that the other party knows your identity and intentions. - ** Attitudes and tone **: Have a gentle attitude and appropriate tone. Do not cause pressure or tension to the other party. Master your body language and expression to make the other party feel comfortable. - Questioning Skills: Ask clear and concise questions to guide the interviewee to answer. Be flexible and adjust the questions according to the interview situation. You can also repeat the questions to help the interviewee understand or summarize their views. - [Tempo Control: Master the pace and speed of the interview to prevent the interviewee from feeling tired or bored.] 4. ** After the interview **: Arrange, classify, analyze, and summarize the interview content to provide reference for subsequent reports or analysis. Reflection: Mastering street interview techniques requires continuous accumulation of experience and continuous improvement in practice. For example, in the confidence-building segment, if the interviewee showed resistance or distrust, he had to think about whether there was a problem with his introduction. In the questioning segment, if the interviewee found it difficult to answer or the answer deviated from the topic, it might be that the question setting was not reasonable enough. In terms of interview rhythm, if the interview process was not smooth, it might be that the pace was not adjusted in time according to the interviewee's state. All of these required the interviewer to constantly sum up his experience and improve his interview ability. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the teaching plan of traffic safety class
The following are some of the main points of reflection on the traffic safety lesson plan: ** 1. Success ** 1. ** In terms of achieving goals ** - In large class teaching plans with traffic safety as the theme, many goals were often set, such as letting children understand traffic rules, recognize traffic signs, and cultivate traffic safety awareness. From the perspective of the implementation of the lesson plan, if the child could accurately identify the meaning of common traffic signs during the activity, for example, when he saw the zebra crossing sign, he could say that it was the place where pedestrians crossed the road. This indicated that the lesson plan had achieved a certain goal in imparting knowledge. - If the child showed an increased awareness of traffic safety after the activity, such as taking the initiative to mention that he should wear a seat belt or not run on the road, it meant that the awareness was cultivated. 2. ** Teaching methods ** - Scenes were one of the commonly used methods. If through the scene performance, the child can actively participate in the discussion, such as seeing someone crossing the road without obeying the traffic signal scene performance, the child can accurately point out the mistake and say the correct way. This shows that the visual teaching method of the scene performance can attract the attention of the child and effectively convey the knowledge of traffic safety. - The game segment was also crucial. For example, in a simulation game like "Little Driver Who Rules", if the child could follow the set traffic rules during the game, it meant that the game activity was effective in strengthening the child's understanding and memory of the traffic rules. 3. ** Child participation ** - When discussing the meaning of traffic signs or judging the behavior in the scene performance, the child could actively speak and put forward his own opinions. For example, when the child saw the behavior of someone sticking his head out of the window in the car in the picture, he could actively express the danger of this behavior. This reflected that the child's participation in the lesson plan activities was high, and the interaction part of the lesson plan design was more successful. ** II. Inadequacies and improvement measures ** 1. ** In terms of depth of knowledge and understanding ** - Some children might still have a superficial understanding of the traffic rules after the activity. For example, even though they knew that they should stop at a red light and go at a green light, they did not have a deep understanding of how to cross the road safely at an intersection without traffic lights. The improvement measures could be to add more practical case studies, such as playing some traffic accident videos at intersections without traffic lights (of course, pay attention to the adaptability of the video content), guiding the children to think deeply about the correct way to cross the road, such as looking left first and then right, making sure that there were no vehicles and quickly passing through. 2. ** In terms of behavior transformation ** - Although the children showed their mastery of traffic safety knowledge in the lesson plan activities, there may be situations where their behavior transformation was not in place in real life. For example, in the lesson plan, the child knew that he couldn't play on the bus, but when he actually took the bus, he might forget it because of excitement. The improvement measures could be to strengthen the cooperation between the parents and the children, so that parents could supervise and guide the children to translate the traffic safety knowledge they had learned into practical actions in their daily lives. Teachers could also add a review session in the follow-up activities, asking the children about their actual performance in life and giving praise or correction. 3. ** Interesting teaching ** - Some of the lesson plans might not be interesting enough, resulting in some children's enthusiasm for participation. For example, when explaining traffic signs, if you simply show pictures and explain, it may make the child feel bored. The improvement measures could be to make the traffic signs into interesting puzzles or card games, so that children could recognize the traffic signs in the game and increase their interest in learning. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Street lights at night, mobile phone photography
Here are some tips for street lamp photography at night: 1. ** Filming preparation ** - ** Device Selection **: Choose a phone with better shooting performance. - ** Location Selection **: Choose a place with unique street lamps and backgrounds, such as ancient streets, bustling commercial districts, or quiet alleys, which can increase the artistic sense. - ** Weather check **: Make sure there is no strong wind or heavy rain during filming to prevent damage to the phone. 2. ** Shooting Techniques ** - ** Shooting Mode ** - ** Night View Mode **: Many mobile phones have this mode, which is convenient to operate and can be used for hand-held shooting. - ** Professional mode **: If the phone does not have night view mode, you can use professional mode. You can adjust the sensitivity to less than 100 to reduce the noise in the photo and improve the image quality. You can adjust the aperture, such as pulling the aperture lever of the Huawei P60 series phone to F4 to the right, and the light can produce a starry effect. You can also set the IS0 and shutter speed to automatic. - ** To avoid glare **: Wipe the lens before shooting to avoid glare due to dirt. However, it was also possible to use the glare to create a different "star" effect, such as horizontally or vertically wiping the phone lens to create different halos. - ** With the help of tools ** - ** Tripod **: It can maintain the stability of the picture, avoid blurring caused by hand shaking, and also gain more exposure time to get a brighter night view. - [Starlight Mirror: A lens filter that can be used to produce a "crosshair" effect.] - ** Use reflection **: The reflection of street lights on the ground can increase the layering and artistic sense of the picture. - ** Composing skills **: A reasonable composition will make the picture more attractive. For example, placing the street lamp on one side of the picture to form a symmetrical or symmetrical composition, or placing it in the background or in the background to increase the layering. - ** Capture Details **: Capture details such as raindrops falling and pedestrians 'reflections to increase the interest and artistic sense of the picture. - ** Metering point selection **: Place the measuring point on the highlight area of the picture (such as street lights) to expose the highlight area accurately. The camera will reduce the exposure and dim the picture to improve the picture quality. If the picture is still not ideal after the measurement, you can manually reduce the exposure. - ** Avoiding vibration **: You can use delayed shooting (timed shooting) and set a countdown of 3 - 5 seconds to avoid the vibration of the phone when the shutter is clicked, causing the image to be blurred. - ** Shooting time **: The best time to shoot is in the evening. At this time, the sky has color details and there is residual light to illuminate the outline of the building. It can be shot with rich colors and clear buildings. 3. ** Post-production adjustment **: You can adjust the color, contrast, saturation, and exposure after shooting to make the photo more stylish and realistic. 4. ** Starlight Effect Added (Late)** - ** Awakening Map software **: download Awakening Map from the application market, import night photos, click "Light" in the special effects, select the starlight effect and make fine adjustments. However, the position of the starlight cannot be adjusted in this software. - **Snapseed software (to make up for the shortcomings of the wake-up picture)**: If the starlight appears in a place that should not appear, use Snapseed to open the photo with the starlight added, add the original image through double exposure, adjust the clarity, and use the mask function to restore the part that does not need the starlight. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Learn photography teaching skills
Here are some tips for learning photography: ** 1. Equipment ** 1. There was no need to master many complicated functions for taking photos with a mobile phone. In terms of camera settings, the "Aperture priority" mode had a high probability of being used, about 80%, mainly used to control the depth of field; the "Shutter priority" mode had a probability of about 15%, suitable for dynamic subject shooting control; the manual mode had a probability of only 5%, which was used when the focus could not be accurately focused. 2. It was important to understand the characteristics of different lenses. For example, the characteristics of a wide-angle lens affected the shooting effect. It should be used reasonably according to the needs. ** 2. Theoretic basis ** Every subject had a theoretical basis, and photography was no exception. It was necessary to study photography theory in depth. This would help to understand photography from the principle and provide guidance for practice. ** 3. Light usage ** 1. When shooting outdoors, the light angles in the morning and evening were the best, and the light quality was the softest. It was easier to take good photos at this time, but at the same time, you had to pay attention to ensure that the subject received perfect light. 2. In different scenes, such as wide-angle shooting, the use of light could not be ignored. ** 4. In terms of composition ** 1. A photo usually involved five main elements: the main body, the accompanying body, the environment, the prospect, and the background. 2. You can use a variety of composition methods, such as diagonal composition, triangular composition, etc. You can also try to take a full-body composition. At the same time, he had to pay attention to the composition of the picture and the guidance of the lines. 3. During the shooting process, you should pay attention to avoid debris, avoid cutting off the main body (such as people, objects, etc.), make reasonable use of the elements in the picture (such as the fence to reflect the sense of depth), and choose the correct focus point. 4. Try some special composition techniques, such as staggering the composition, capturing a picture-in-picture effect, and using elements such as windows to enrich the picture. ** 5. Other Points of Shooting ** 1. There were a lot of important points to pay attention to when it came to landscape photography. For example, you have to run hard to find a suitable shooting spot for a big scene; The light is better in the morning and evening, but the light is not good at noon; You should pay attention to the atmosphere of the wonder, and don't let go of the opportunity to shoot in rainy and foggy weather; You can also bring a camera when the weather is bad, and it may clear up in the evening; When using the big bottom plus slow film, the tripod shutter release, the zoom lens should be fixed as much as possible; Take off the protective mirror and put on the hood, the tripod should be locked tightly, and the mirror should be pre-locked; The scenery is gray, white plus black minus; During long exposure, measure the light frequently and pack a few photos up and down; Negative film should be slightly reduced, positive film can be slightly reduced; Wide-angle focus on the theme, telephoto compression scene; Small aperture depth of field is large, full open can paste the background; For flower shooting, use side backlighting, slow door to show dynamic; Stream is suitable for long exposure; Look for side light when seeing mountains, and shoot reflection when seeing water; Focus on the theme, level should be flat; Polarizer to remove reflection, gradual mirror to flatten contrast; When the contrast is too large, use black card; Long exposure should avoid car lights, rock wet shooting effect is good, etc. 2. In scenes such as portraits, one had to pay attention to the presentation of the character in the picture to avoid the character being cut off. The focus should be accurate (for example, the character corresponding to the eye-catching element should be focused accurately), and the messy elements in the picture should be avoided to interfere with the main body (for example, the interference elements on the ground should be avoided in crowd shooting). 3. Post-processing was also an indispensable part of photography. When shooting, one had to consider the possibility of post-production. For example, equipment with high enough resolution could be cropped later. If the resolution was not high enough, one had to pay attention to avoid the problem of image blurring that might be caused by post-production. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The traffic lights blink, lesson plan and reflection, small class
The following is a lesson plan and reflection for the small class: ** 1. Teaching plan ** #"Blinking at the traffic lights" lesson plan ##(1) Activity Target 1. Let the children know that cars and pedestrians on the road must obey the traffic rules and obey the command of the traffic lights. 2. It could move according to the signal. 3. Experience the joy of imitating games and enhance children's safety awareness. ##(2) Event preparation 1. A toy car, a personified red light, green light, yellow light, a television, and a LCD. 2. You can also prepare a background map of an intersection. ##(3) Activity 1. ** import ** - Teacher: Today, the teacher brought a few beautiful pictures for the children. Do you want to see them? (Thinking) 2. ** Know the traffic lights ** - Play the pictures (red light, green light) and observe the children. - Question: (1) What do you see? (2) Where have you seen traffic lights? (The child answers freely) - Play (Wait for the red light) The child continues to observe the picture and guides the child to stop when the red light is on. - The red and green lights are used to direct traffic. They tell us to stop when the red light is on and to go when the green light is on. They are to let us abide by the traffic rules. If there are no traffic lights, the cars will be very chaotic when passing through the crossroads. It is easy to be dangerous. We will be safe if we walk according to the traffic rules. (Self-made red, green, and yellow lights are introduced.) - The teacher said,"Teacher, there are also red, green and yellow lights here. Do you want to see them?" Then, show the children the functions of the red and green lights, and ask the children about the function of the yellow light to guide them to think. 3. ** Game segment ** - ** Mini games: Driving a Car ** - Find some children to imitate "driving" and show them red, green and yellow lights respectively. (Split into groups) - The toy car was brought out, and the teacher sang,"Little car, so beautiful, really so beautiful, toot…" - He pretended to look for the person who was singing and then showed the toy car and the crossroad background. - (Showing the toy car) A small car had just come out of a car factory and was wondering about everything. Seeing the bustling streets and roads, it was so happy that it kept chirping. It would drive east and then drive west. It was free! Suddenly, it saw something blinking on the street. It felt very strange. Then he asked the children: (1) What does blinking at the red light tell us? What does the blinking green light tell us? (2) What happens if there are no traffic lights? (3) Can't a small car drive on the road without knowing the traffic lights? - ** Game: Listen to the command at the traffic lights ** - Ask the child to make a driving posture. The teacher will show the "red light","green light" and "pedestrian" signal signs in turn, and the child will make the corresponding actions accordingly. 4. ** Activity summary and extension ** - [The car has been driving for a day. It's tired and wants to go home.] Children, we're tired from driving. Why don't we take a break? (Okay) - Activity extension: Pay attention to the traffic lights when crossing the road with your parents. ** 2. Reflection ** #Reflection on the lesson plan of "Blinking at the Red Lights" ##(I) Achievement of the goal 1. ** Knowledge target ** - Most children could understand that cars and pedestrians needed to obey traffic rules and obey the traffic lights. During the activity, through the pictures, questions, and games, the children had a clearer understanding of the concept of stopping at a red light and going at a green light, and basically achieved their knowledge goals. 2. ** Skill Target ** - Most children could react more sensitively to the signal. However, there are still a few children who have slow reactions and may need to add more practice opportunities in future activities. 3. ** Emotional goal ** - Judging from the enthusiasm of the children to participate in the game, they experienced the joy of imitating the game. In the communication after the activity, the children showed that they paid attention to the rules of crossing the road, strengthened their safety awareness, and achieved their emotional goals better. ##(2) Teaching Method 1. ** Strengths ** - The use of intuitive teaching methods, such as playing pictures, showing self-made traffic lights and other teaching aids, in line with the cognitive characteristics of small classes, can attract the attention of children and help them better understand the teaching content. - The game teaching method was used throughout, allowing the children to learn traffic rules in a relaxed and happy atmosphere, increasing the participation and enthusiasm of the children. 2. ** Inadequacies and improvements ** - When explaining the function of the yellow light, perhaps because the explanation was not simple enough, some children had some difficulty understanding it. In the future, more vivid analogies or examples could be used to explain the transition effect of the yellow light. For example, the yellow light was an early warning signal that the color was about to change, just like we had to slow down when we were about to reach the end of a run. ##(3) Event Organization 1. ** Strengths ** - The activity segment was designed to be compact and the transition was natural. From the introduction to the recognition of traffic lights, to the game segment, and finally to the summary and extension, each segment was closely connected and clearly divided, which could guide children to gradually learn the knowledge of traffic rules. - Teachers could better guide children to think and answer questions in the activities, encourage children to actively participate, and create a positive classroom atmosphere. 2. ** Inadequacies and improvements ** - When organizing the game segment, some children were too excited and violated the rules of the game. Although the teacher corrected the problem in time after discovering it, he could clarify the rules of the game before the game and emphasize the importance of abiding by the rules to avoid similar situations from happening again. ##(IV) Children's Performance 1. ** Positive aspects ** - The children showed a strong interest in the content of the activity and were able to actively participate in all aspects. In the questioning session, the children could speak boldly and express their thoughts and opinions; in the game session, the children could cooperate happily with their peers and actively make corresponding actions according to the traffic lights, showing a good sense of teamwork and learning ability. 2. ** Area to be improved ** - Some children had short attention spans and were easily disturbed by the surrounding environment. In future activities, you can adjust the rhythm of the activity appropriately and add some elements that attract the attention of the child, such as interesting stories, small animations, etc., to improve the child's concentration. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Dance skills, donkey roll, teaching plan reflection, short
If one looked at the existing teaching plan of the kindergarten, its advantage was that the teaching goal was clear, the teaching content was rich, and it was gradual. From the action teaching to the combination of music rhythm to the interaction game, the overall structure was relatively complete. However, there were still some areas that could be improved. In the teaching process, for children with poor physical coordination, the donkey rolling action may have some difficulty. Perhaps more auxiliary guidance exercises should be added. In the interaction game segment, although the use of props increased the fun, it might cause some children to pay too much attention to the props and distract their attention from the action. It was necessary to better balance the relationship between gameplay and teaching goals. In addition, in terms of teaching evaluation, the current focus was mainly on the evaluation of action performance, which might have neglected the psychological experience and the persistence of interest stimulation in the learning process of children. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
