On-site photography experiment report
The following is an example of a live photo experiment report: ** 1. Purpose of the experiment ** Through taking photos on the spot, he studied the effects of different shooting conditions (such as shooting equipment, shooting distance, focusing object, etc.) on the image of the photo. At the same time, he mastered the basic operations and precautions during the process of taking photos on the spot. ** 2. Experimental Equipment ** 1. ** Device 1 **: A common mobile phone on the market with autofocus function. 2. [Equipment 2: Common single-lens reflex camera.] ** 3. Experiment process ** 1. ** Mobile phone photography experiment ** - Setting the shooting distance: The photographer stood about 2 meters away from the person being photographed. - Focus: The phone automatically focused on the face, and the outline of the fingers was very blurry. This meant that at this distance, when the phone focused on the face, the image of other parts (such as fingers) was lower. 2. ** Experiment with a single-lens reflex camera ** - The first shot: The photographer stood at a certain distance (not explicitly mentioned but the distance was more conventional), and the fingerprints taken were not visible at all. This could be because the camera's default focus setting or the shooting distance did not meet the requirements for a clear fingerprint. - The second shot: The photographer stood less than 50 centimeters away from the photographer, took the photo with a single-lens reflex camera, and focused on the finger. The fingerprint was still unclear. This showed that even at a close distance and focused on the finger, the clarity of the fingerprint captured by the DSLR camera was still limited. ** 4. Experiment results and analysis ** 1. ** The relationship between the imaging effect and the focused object ** - In live photography, the autofocus function of the camera would prioritize focusing on a specific object (such as the face of a mobile phone), which would affect the clarity of other objects. If you want to capture a specific object (such as a fingerprint), you need to manually adjust the focus of the object, but even so, it is difficult to obtain a clear fingerprint image under normal shooting conditions. 2. ** The influence of shooting distance on imaging ** - From the experiment, whether it was a mobile phone or a single-lens reflex camera, it was difficult to clearly image the fingerprint when the finger was taken from a distance (such as 2 meters and above). Even if the DSLR camera focused on the finger at a close distance (less than 50 cm), the fingerprint image was not clear. This meant that for situations where high-precision imaging was required, such as taking fingerprints, it was difficult for conventional shooting distances to meet the requirements. ** 5. conclusion ** Through this on-site photography experiment, it was known that under normal shooting conditions, whether it was a common mobile phone or a single-lens reflex camera, it was very difficult to clearly capture details such as fingerprints. This was related to the device's autofocus mechanism, shooting distance, and imaging ability. Read more exciting novels for free
Experiment Report on Vegetables Identification
The vegetable identification experiment report was an experimental method that aimed to learn and recognize different types of vegetable seeds and seedlings by observing the external shape and internal structure of vegetables, as well as the methods to distinguish them. The experimental materials included dried seeds and germinated seeds of various vegetables, such as radishes, Chinese cabbage, cucumbers, leeks, and so on. The experimental steps involved observing and identifying the characteristics of the leaves and the initial true leaves of the vegetable seedlings, as well as determining the names of various vegetable seedlings based on physical samples. The identification and sprouting experiment report of vegetable seeds also included the records of the seed's shape and characteristics, as well as the methods for determining the seed's sprouting rate and sprouting potential. Through these experiments, one could master the classification and morphological characteristics of vegetable seeds, which would provide a foundation for further study of vegetable cultivation.
Introduction to Computer Experiment Report
The experience of an introductory computer experiment report usually contained a variety of content. In terms of gaining knowledge and skills, one would realize the importance of combining theory and practice. For example, in the past, one might think that one's theoretical knowledge was enough, but in practice, one would find many problems. For example, when writing a program, even if it was a program copied from a textbook, there might be many errors in actual testing. This showed that practice was the key to testing the mastery of knowledge. Only through a large number of computer operations could one truly master the relevant knowledge in the introduction to computer science. From the perspective of the course content, through the computer introduction experiment, you can understand things like numerical values and coding.(The conversion between the binaries, octals, decimals, and hex, the representation of the original code, complement code, and code shift, the representation of fixed-point numbers and floating-point numbers, etc.), arithmetic operations and logical operations (fixed-point addition, multiplication, and division, floating-point operations, and logic operations, etc.), as well as the arithmetic logic unit (the function and structure of the ALU, etc.). At the same time, in terms of overall quality improvement, it helped to improve independent thinking and hands-on ability. When working on projects or solving problems in experiments, one needed to rely on oneself to think of solutions, manually debugged code, and so on. This was a good exercise for one's self-ability. Moreover, it could also enhance the ability of teamwork. During the experiment process, it might be necessary to cooperate with classmates to complete tasks together, so as to realize the importance of teamwork in computer related projects. In terms of the impact on future studies and career development, computer science introductory experiments could make people clear their direction in professional knowledge learning. If he found that he had difficulty understanding and operating a certain piece of knowledge during the experiment, he could strengthen it in the subsequent learning. Moreover, this kind of experimental experience could also make people realize the requirements of the computer science profession in real work, and encourage them to constantly improve to adapt to the needs of society.

Comprehensive photography analysis report
The following is an example of a comprehensive photography analysis report: ** 1. Picture composition ** 1. ** Main body protruding method ** - ** Form of composition **: Common composition forms such as the golden ratio composition can make the subject in the most attractive position in the picture; symmetrical composition gives people a sense of stability and balance; frame composition uses the elements in the picture to form a frame to highlight the subject. For example, in the photography work "Look at the Bride," the author uses the frame structure of the window to form a frame composition with the outline of the window, focusing the audience's attention on the wedding scene elements inside and outside the window. Triangular compositions and various linear compositions also had their own characteristics. They attracted the attention of the audience by constructing the main body or related elements into a specific shape. - ** contrast technique **: The contrast of light and dark can make the subject stand out from the background. For example, when taking a portrait, the subject's face will be illuminated, and the background will be in the dark, so the subject will be more distinct. The contrast between the cold and warm colors could also play a role in emphasizing the main body. For example, under the blue background, the orange main body would be particularly eye-catching. The contrast between the real and the virtual was equally effective. By focusing the main body and blurring the background, the audience could focus on the main body. - ** Area ratio **: The size and proportion of the main body in the image greatly affects the degree of the main body's prominence. If the proportion of the main body in the picture was too large, it might make the picture seem crowded, and if the proportion was too small, it might be ignored. For example, when shooting a character in a landscape, the size of the main body of the character needed to be determined according to the theme you wanted to express. If you wanted to reflect the insignificance of the character in the grand landscape, the proportion of the character would be small; if you wanted to highlight the activity of the character, the proportion of the character in the picture should be appropriately increased. 2. ** Filming farewell scenes ** - ** Vision **: Able to display a wide range of scenes and give people a macro view. It is suitable for displaying the magnificent scenery of nature and large-scale crowd activities. For example, shooting a mountain range or a large-scale gathering, the distant view could give the audience a comprehensive understanding of the overall scene. - ** panoramic view **: It is more focused than a distant view. It can completely present the whole picture of a scene or a character, including the posture of the character and the surrounding environment. For example, taking a picture of a building or a person's clothing and posture. - [Mid Shot]: It mainly shows the half of a character or a part of the scene, emphasizing the character's movements, expressions, or the relationship between the main elements in the scene. Mid shots were more commonly used when shooting scenes of people talking or when shooting indoor decorations. - Close-up: Focus on depicting the facial expressions of the characters or the details of the objects, allowing the audience to feel the emotions of the subject or the texture of the objects. For example, if you took a close-up of a person's face, you could clearly see the person's eyes, expression, and other emotional information. - [Close-up]: It is to magnify a certain part of the subject, such as the eyes of the person, the stamen of the flower, etc. Close-up can show very delicate details and enhance the visual impact of the picture. ** 2. Shooting angle ** 1. ** vertical angle ** - ** Overlooking **: Shooting from above will make the object look smaller, which is suitable for the layout and scale of the scene, such as shooting the layout of the streets of the city or the overall scene of a large-scale event. The bird's eye view could also create a feeling of macro control. - ** Looking Up **: Shooting from the bottom up can make the subject look tall and majestic. It is often used to shoot buildings to emphasize their height, or to shoot people to show their majesty and confidence. However, when shooting characters, you should pay attention to avoid distortion caused by looking up, such as the character's chin being too large. - [Level View]: Take photos at the same level as the subject, giving people a sense of equality and closeness. When shooting a conversation or an object from a head-up perspective, it could truly reflect the shape of the object and the expression of the person. 2. ** Horizontal angle ** - ** Front **: Showing the front of the main body can directly show the whole picture of the main body, but if it is not handled well, it may appear dull. When shooting a character from the front, one had to pay attention to the coordination of the character's expression, eyes, hands, and other body language. For example, if the character's eyes and hand movements did not respond, the picture would appear unnatural. At the same time, if the person looked up when shooting from the front, it might make the face look wider unless there was something covering the cheek bone to modify the shape of the face. - ** Side view **: The side view can show the outline of the subject, which is very effective for showing the figure curve of the character or the shape and characteristics of the object. - ** Back view **: Shooting from the back often leaves more room for imagination for the audience. It can convey an artistic conception or emotion through the back view. For example, shooting a person's back view walking into the distance can express loneliness, exploration, and other emotions. ** 3. Use of Light ** 1. ** Nature of Light ** - ** Direct Light **: Can produce a strong contrast between light and dark, forming clear shadows, suitable for shaping the three-dimensional sense and texture of objects. It was more suitable for shooting tough objects or scenes that needed to emphasize light and shadow effects, such as shooting metal sculptures. - ** Scattered Light **: The light is soft and will not produce obvious shadows. It is suitable for shooting scenes that require delicate performance. For example, when shooting a portrait, the scattered light can make the skin of the character look smooth and soft. - [Reflected Light]: The light reflected by the reflective object can be used to supplement the light or create a special light and shadow effect. For example, using a reflective board to fill in the light on the character's face, or using the light reflected from the water to create a unique light and shadow atmosphere. 2. ** The direction of light ** - ** Straight Light **: The light is in the same direction as the shooting direction. It can make the subject receive light evenly and the color is bright, but it lacks the three-dimensional effect. It was often used in scenes where the details and colors of the main body needed to be clearly displayed. - [Backlight: The light comes from the back of the main body and can outline the outline of the main body, creating a mysterious and dreamy atmosphere. However, the front of the main body is easily under-exposed.] Backlighting could be used when shooting silhouettes or when you wanted to highlight the outline of the subject. - [Side Light]: The light shines from the side of the main body, creating a clear contrast between light and dark, enhancing the three-dimensional and texture of the object. It is a more commonly used light direction. - ** Top Light **: When light shines from the top, it will produce shadows below the main body. In portrait photography, it may cause unsightly shadows on the face of the person. You need to pay attention to adjustment or fill in the light. - [Underlight]: The light shines from the bottom up. It is rare and is usually used to create a special terrifying and mysterious atmosphere. 3. ** Light ratio ** - The proportion of shadows and highlights in the picture would affect the overall atmosphere and contrast of the picture. A picture with a large proportion of highlights would appear bright and light, but if it was too much, it might cause the details to be lost. A picture with a large proportion of shadows would appear heavy and mysterious, but if there were too many shadows, it might make the picture look depressed. ** 4. Color ** 1. ** Warm and cool colors ** - ** Warm colors (red, orange, yellow)**: Can convey passion, vitality, warmth, and other emotions. Using warm colors as the main color in the picture would give people a positive and energetic feeling. For example, when shooting sunrise and sunset, the warm colors of orange and red dominated, creating a warm and romantic atmosphere. - ** Cold colors (green, blue, purple)**: Often associated with calmness, steadiness, mystery, and other emotions. Using cool colors as the background, such as a blue sky or a green lake, could add a sense of tranquility and depth to the picture. If the combination of cold and warm colors was appropriate, it could produce a strong color impact. For example, the combination of blue background and orange main body could attract the eye and show a rich emotional level. ** 5. Other aspects ** 1. ** The cooperation between the model and the photographer ** - The pose, expression, and movements of the model were closely related to the photographer's framing and shooting angle. For example, if the model's posture was not suitable, it might cause the image to be taken at a bad position, such as the bust being taken at the wrist. The photographer needed to adjust the angle and guide the model's movements according to the model's characteristics and the theme they wanted to express. If there was a problem with the angle of the camera, such as making the model look wide or produce an unnatural expression (such as turning the eyes to the corner of the eye when looking up), it could be solved by adjusting the model's posture (such as holding hands behind his back to avoid the problem of wrist capture) or changing the camera position (such as moving back and forth to avoid obstacles such as tree trunks above the model's head). 2. ** The creativity and ideas of the work ** - In addition to technical analysis, photography also carried the photographer's creativity and thoughts. Some works used unique compositions, color combinations, or shooting techniques to express a certain emotion, tell a story, or convey a concept. For example, moving objects that originally belonged to the room into nature, or using transparent plastic film to capture the shape of the wind and other creative techniques could show the photographer's unique perspective and innovative thinking. When the camera was aimed at the elderly woman, it did not show her suffering to the public, but showed her elegant strength. This reflected the photographer's unique understanding of the subject and the positive values he wanted to convey. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The collection of site photography and material evidence
** 1. Scene Inspection and Photographer ** 1. ** Shooting Steps ** - Usually, they would shoot the location of the scene first, then the general picture of the scene, then the key parts of the scene, and finally the details. 2. ** Shooting principles ** - They followed the principle of shooting the original first, then shooting the changes; shooting the key points first, then shooting the general; shooting the easy things first, then shooting the difficult things; shooting the things that were easy to disappear and be destroyed first, then shooting the things that were not easy to disappear and be destroyed. - It was required to reflect the subject objectively, truthfully, and comprehensively. There should be no artistic exaggeration, and the image should be clear, moderate contrast, and distinct. And the content of the photo should be consistent with the relevant records of the traffic accident investigation record. During the survey, the shooting project could be determined according to the needs and actual situation. There should be panoramic photos reflecting the full scene of the accident scene, as well as close-up photos reflecting the damaged vehicle number plate and the location and degree of damaged property. ** 2. Collection of material evidence ** 1. ** Meaning ** - Physical evidence was the most objective basis for analyzing the cause and responsibility of the accident, and it was the core work of on-site investigation. All kinds of investigation techniques, methods, and means were used to collect physical evidence. 2. ** Method ** - The key to collecting physical evidence was to recognize and discover physical evidence, and use scientific means and methods to obtain physical evidence. During the investigation of the scene, investigators used various instruments and professional techniques to discover and extract traces, items, and other physical evidence related to the accident. They could also obtain witnesses through interviews with the people at the scene of the accident. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Books on photography and photography techniques
Personal photography, travel photography
The following are some of the key points related to personal photography: ** 1. Initial preparations ** 1. ** Costume matching ** - They had to choose suitable clothes according to the different scenery. For example, in a small and refreshing scene like the rape field, it was better to wear light-colored, casual clothes. It was more appropriate to avoid red and purple, high-end and stylish clothes, such as white T-shirts and blue denim overalls. At the same time, the matching of clothing should consider the coordination with oneself and the environment, including makeup, styling, and so on. 2. ** Equipment preparation ** - Cameras or mobile phones could be used for travel photography. If you used a camera to take a selfie, you might need to buy an additional remote control. Some cameras could be connected to the phone through Wifi, and you could see yourself in the camera in real time on the phone screen for composition. The phone also had a variety of selfie functions, such as timed shots (the Glory 30S phone's photo page had "2 seconds, 5 seconds, 10 seconds" options), voice-activated photos (useful in quiet environments), and smiley face shots (better lighting, more practical within 5 meters). ** 2. Techniques and taboos during filming ** 1. ** In terms of composition ** - To avoid taking pictures from the hands, feet, and joints of the subject. When setting up a selfie, set up the tripod, put the camera or phone on, and adjust the camera position and composition. For example, when you want to be a part of the scenery or take a photo at a scenic spot, you can set a delayed selfie or even continuous shooting to adjust the ideal composition. - Pay attention to the position of the character in the picture, avoid being rigidly in the middle of the picture, and make the character and the background form an organic whole. - If there are horizontal lines (such as the sea, the lake) or the horizon (such as a sea of flowers), avoid these lines crossing the main parts of the character (such as the head and neck). If it is unavoidable, try to move the horizontal line below the shoulders of the character. 2. ** Selection of background ** - When taking portraits, the background should be carefully selected and the scenery with local characteristics should be used as the background, but the background should be avoided. If too many elements entered the picture, it would make people dazzled and lack highlights. The background color had to be unified so that it could better highlight the characters. 3. ** Face and posture ** - If his expression and posture were not good, he could take more photos to solve it and increase the probability of taking a satisfactory photo. 4. ** To prevent the host from being overshadowed by the host ** - The accompanying objects in the scene (such as green plants, utility poles, etc.) could not be more eye-catching than the characters. Generally, the accompanying objects should not be larger than the main body, and the colors should not be brighter than the main body. Otherwise, it would distract the audience's attention on the characters. ** 3. Shooting Techniques (Shot Manipulation, etc.)** 1. ** Video Shooting (if involved)** - He could use a low-angle mirror lift (push forward), surround (take a picture of the scenery), and lower (finish). - There was also tension composition, upside-down horizontal shooting, graphic composition, telephoto shooting, leaf gap, backlighting shooting, ant perspective, leaf reflection, lock focus first, surround shooting, looking for light and shadow, side framing, road extension, overall finishing, and other techniques to create a cinematic feel. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
documentary photography and commercial photography
There were many differences between documentary photography and commercial photography: - ** Purpose **: - The focus of documentary photography was to record stories and events with meaning and meaning. When combined with words, it could carry and record human society and civilization. Behind the photos were often thought-provoking stories, important events, or symbols of an era that inspired people's memories and thoughts. It had a wide spread value and archive value. Moreover, excellent documentary photography should be able to guide the viewer to think according to the "50,000 thinking mode". The photographer not only exposed the problem but also provided a solution. He even directly threw himself into activities that changed the reality of society. - Commercial photography conveyed the power and commercial value of a brand as quickly as possible. It was a visual form that served the business. Its main purpose was to promote products, services, or brand images. - ** Focus **: - The difficulty of documentary photography lay in the grasp of the story of the character. Although light, color, and composition were also required, the importance of the story was ranked first. It required the photographer to find interesting things in ordinary places, think quickly, and capture them quickly. It was necessary to objectively reflect the content or essence of the event as much as possible, with less subjective nature. If there was too much human intervention, the work would lose its authenticity, and it would not be a good documentary photography. - Commercial photography focused on the exquisiteness of the form and had high requirements for the visual effects of the picture, such as lighting and composition. It was to create an attractive visual image to serve the commercial goal. - ** Attributes **: - It was a unique art form of photography that could not be replaced by other art forms. - Commercial photography was essentially no different from other forms of visual services for business. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
