Using practice to measure the temperature of photography
Based on context alone In the field of photography," measuring the temperature of photography with practice " had rich implications. In terms of technical practice, photographers needed to constantly pick up the camera to practice shooting. For example, shooting under different lighting conditions, such as soft sunlight in the morning, strong direct light at noon, or artificial light at night, by adjusting the aperture, shutter speed, sensitivity, and other parameters, you can feel the impact of these elements on the final effect of the picture. During the shooting process, one would gradually understand what kind of parameters could capture the most touching moment, just like accurately capturing the warm color of a bonfire in a cold environment, or the comfortable expression of people enjoying the cool on a hot summer street. This was the visual "temperature" in the perception of the image. From the perspective of creative practice, shooting in different scenes and crowds was also a way to measure the temperature of photography. They walked into the ancient village and filmed the persistence and inheritance of traditional craftsmen. Their focused expressions, rough hands, and ancient tools conveyed a kind of persistence and love for traditional culture under the camera. This temperature was a respect for cultural inheritance. Or walk into the corners of the city and record the figures of ordinary workers. Whether it was the cleaners cleaning the streets in the morning or the delivery men who were busy late at night, the images captured by the camera reflected the true temperature of life. From the perspective of emotional experience, the photographer used his own emotional input to find those warm images. For example, the interaction between relatives during family gatherings, the joy of the family when a newborn was born, the grief of relatives when an old man passed away, and so on. Every time the shutter was pressed, it was a measure of the temperature of these emotions. The invisible emotions were solidified by photography, allowing the audience to feel the love, joy, sadness, or hope through the photo. In short," measuring the temperature of photography with practice " was to explore the depth and breadth of photography through continuous shooting practice, from technology, creative content to emotional expression, so that photography works were full of appeal and vitality.

Can the infrared camera on the phone measure the body temperature?
The infrared function of some mobile phones could be used to measure body temperature, but not all mobile phones with infrared camera function could measure body temperature. For example, the Glory Play4 Pro had an infrared temperature measurement function with the help of the infrared sensor on the back, which could measure the body temperature of humans and animals as well as the temperature of objects. The Google Pixel8 Pro and Pixel9 Pro were equipped with temperature sensors to achieve temperature measurement, and through technical updates, the temperature sensor could automatically identify the material of the object being measured to improve the convenience of temperature measurement. However, the infrared camera function of the mobile phone was mainly used for night scene imaging and other purposes. In most cases, it could not be directly used to measure body temperature. The temperature measurement function required specialized sensors and related technology to support it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Using pictures in photography
I don't quite understand the exact meaning of your expression,'photography uses picture'. If you want to ask how to use composition to make a picture more beautiful, here are some common methods: - Rule of thirds: Place the subject at the intersection of the picture to make the picture harmonious. - Symsymmetrical composition: suitable for shooting objects such as buildings, can show a sense of stability. - Multi-dimensional composition: In addition to the front and back, adding a middle shot can make the photo more interesting and help tell the whole story. For example, the front is a road with lanterns, the middle is a small house, and the background is the sunset sky. If you want to ask how to use light to make the picture look better in photography: - Shunguang was suitable for taking fresh scenery photos. - Backlight shooting can show a unique silhouette, but pay attention to the details such as the person's expression and hair. If it's not a special shot but a person, the person is on the "line" in the line shooting and the distance from the lens is larger, or the color of the person in the distance is different from the overall environment, which can make the subject more obvious. - Side light can make objects more three-dimensional. During the filming process: - Using different shooting angles, the top-down shot could show the whole picture, and the top-up shot could highlight the height. - Using the depth of field technique, when the depth of field was large, the distance could be clearly shot. When the depth of field was small, the background would be blurred, making the picture more attractive. - For scenes with lines, you can shoot along the line to form a guide and increase the sense of depth. However, it should be noted that not all lines are suitable for shooting along the line, and there must be a combination of front and back. It is best to have people or scenes on the line to avoid holes. If you want to ask how to deal with the photos in the later stages of photography, you can adjust the color temperature and saturation to make the photos more colorful. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to measure light in a single-lens reflex photography
The measuring method of a DSLR character photography depends on the light, light ratio, and the situation of the character in the picture. The following are some common measuring methods: ** 1. Average Metering (Global Metering)** 1. ** Usage Scenarios ** - It was suitable when the light was relatively flat or when the proportion of the characters was small when shooting a big scene. Because the exposure of the entire frame (including the area outside the character) needed to be considered, this mode would calculate the light measurement of the entire viewing area. For example, it could be used to shoot a full-body image of a person in a large scene, and the light was evenly scattered throughout the entire scene. 2. ** Effects and characteristics ** - In the shooting range, the light was relatively uniform, and the contrast between light and dark was not large, so a satisfactory exposure could be obtained. ** 2. Center Average Metering (Center Weighted Metering)** 1. ** Usage Scenarios ** - It was used when the main body of the character was in the middle of the shooting range, and there was a big difference between the brightness of the environment and the main body. For example, if the character is in the center of the picture and there is a bright or dark background behind it (such as the character standing in front of a window or a dark door), this mode will calculate the light measurement value for 10 - 30% of the frame (mainly in the center of the picture), which can make the exposure of the subject more accurate. - If the characters are concentrated in the middle of the screen, you can also choose this light measurement mode. 2. ** Effects and characteristics ** - Using the central area of the screen as the most important light measurement reference area, while taking into account the light measurement data of some other areas, so that the main body's exposure was normal and the surrounding environment's shadow tone could be taken into account. ** 3. Spot Metering ** 1. ** Usage Scenarios ** - It is recommended to use the spot meter mode when shooting at a high light ratio or when shooting at the main position of the person (such as the face of the person in a close-up shot) or when shooting against the light. This mode allowed the exposure of key parts such as the face to be more accurate. For example, when shooting the outline of a person under the setting sun, it could be used to ensure that the person's face was clearly and accurately exposed. - When shooting in silhouette mode, the spot measuring mode was also suitable, but the measuring point had to be chosen in a place with a brighter background. - When the character is single and requires precise control of the character's exposure, you can also choose to spot light. 2. ** Key Operation Points ** - Some cameras could directly set the focus point to the center focus point to achieve the synchronization of focusing and measuring. That is, first set the focus point to single-point focus and set it to the center focus point, then press the shutter halfway to the position to be measured (such as the highlight area of the person's face or the key part to be accurately exposed) to focus and measure, then press the lock exposure button to lock the exposure, and finally focus and compose again. 3. ** Effects and characteristics ** - The camera only measured a small part of the central area of the picture (usually about 1% - 5% of the area around the central focal point of the optical viewfinder) with a high degree of accuracy. In addition, when using the camera's built-in light meter to shoot a portrait, you can also prepare an 18% photographic gray plate to help with light measurement. If you find that the camera's auto-exposure value is inaccurate, you can manually adjust the exposure compensation to adjust the brightness of the photo to make it brighter or darker. At the same time, when choosing the light measurement point, the light measurement point was usually placed on the white of the person's eyes to ensure that the facial features and face were properly exposed. If the face was very bright, the light measurement could be carried out in the bright areas such as the eyes or nose. If the face was very dark, the light measurement could be carried out in the darker areas such as the lips or chin. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Using plants to describe photography
Plants had a unique position in photography. Just like the various elements in photography, they had many symbolic meanings. From the perspective of light and shadow, plant photography was closely related to the use of light and shadow in photography. Just like how plants could not grow without light, photography also needed to use light and shadow to shape the image. The forward light was like the front of a plant that received light evenly. It could clearly show the details and contours of the subject, just like the vitality and complete form of a plant under sufficient sunlight. The backlighting was like the backlighting of a plant. The petals were thin and transparent, or the flowers had distinct layers. It could be used to express a special artistic sense in photography. For example, in portrait photography, backlighting could create a unique atmosphere, so that beautiful contours appeared on the edges of the hair. Side light was in between the two. Just like how it could reflect the petal level and flower details when illuminating a plant from the side, it could also portray the texture and details of the subject when taking a photo. From the perspective of the composition of the picture, there were various forms of plants, and it could be used to simulate different composition elements in photography. For example, tall trees could symbolize the vertical line elements in the picture, adding stability to the composition; the spreading vines could be similar to guiding lines, guiding the audience's line of sight; the gathering of flowers was like a visual focus in the picture, like the main part that wanted to stand out when taking photos. In addition, the color of the plants was also very important in photography. Plants in different seasons had different colors. The freshness of the green plants and the colorful flowers were just like the color combination in a photo. The right color combination could create a different atmosphere, just like how the verdant plants in spring gave people a sense of hope and vitality. In photography, soft colors could also convey emotions such as tranquility or joy. Moreover, the brightness of the plants could be changed by the intensity of the light. This could also affect the visual effect of the picture and the psychological feelings of the audience through the adjustment of the color. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What to practice with in single-lens reflex photography?
The following are some ways to practice with DSLR photography: ** 1. Start by familiarizing yourself with the camera ** 1. ** Basic camera operation parts ** - First, he grasped the way to hold the camera. He wrapped the camera rope around his wrist or neck, held the opening on the right with his right hand, and naturally held the lens under the zoom ring with his left hand. The index finger or middle finger of his right hand was on the shutter button, and his thumb was on the dial to adjust the camera. - He learned how to install the battery and memory card, how to charge the battery and install the battery and memory card, how to turn on the camera (such as turning the top of the camera on), how to use the shutter button (press the focus button halfway, press the camera button after the focus is successful), how to install and replace the lens, how to view the screen, and other basic operations. 2. ** Setting of camera parameters ** - The focus was on mastering the three basic imaging parameters, namely the sensitivity, shutter speed, and aperture. The higher the sensitivity, the brighter the image; the smaller the shutter speed (the faster), the clearer the moving object, but the light will become darker; the smaller the aperture (the larger), the brighter the light, and the larger the aperture can shoot objects with high depth of field. - Try to manually adjust the shutter, white balance, framing, and focus in the manual mode (M gear) to familiarize yourself with the effects of various camera settings on the image. ** 2. Practice from different shooting scenes ** 1. ** Take close-ups of small, still objects (like flowers, birds, insects)** - You can use the Av gear, set the aperture to f5.6 or below, focus at 50 or above, and try to shoot within 1m. This can make the background blur, so you can practice close-up shots of specific subjects and master the creation of the background blur effect. 2. ** Shooting characters ** - Basically, use a larger aperture (within f5.6) and a focal length of 50mm or above. The shooting distance is determined according to the full body, half body, and head shot. The background is blurred. The Av file is used for shooting. Through shooting people, the main body of the character is highlighted and the background is processed. 3. ** Shooting Scenery ** - Using the Av file, choose an aperture above f8, and the focal length can be adjusted according to needs (pay attention to the wide-angle distortion). Practice the aperture selection in landscape photography and how to deal with wide-angle distortion and other problems. 4. ** Shooting Night Scenery ** - Mount the tripod, use Av gear, customize the white balance or incandescent lamp, use an aperture of f8 or above (a small aperture can make the light appear like starlight), use the pre-raised function of the reflective board, cover the viewfinder with the square cover on the strap to prevent stray light from entering, control the IQ to be within 200, and extend the exposure time. Through this method, practice the control of the image quality and reduce interference factors in the night scene shooting. 5. ** Shooting fireworks ** - Use the shutter release and B shutter to shoot fireworks. Try to shoot the effect of overlapping fireworks and master the special shutter skills in shooting fireworks. 6. ** Capture a moving object ** - When the light is good, use the Av gear and adjust the aperture size as appropriate. If you want to shoot a large depth of field, use an aperture above f8, and the opposite for a small depth of field. If you want to shoot a dynamic effect, you can use the Tv gear. The shutter is about 1/30. When you focus, press the shutter and move the lens to chase the subject. This is to practice the shooting skills of dynamic objects. 7. ** Shooting water or fountains ** - Using the Tv gear and a shutter speed of about 1/50, practice shooting a satin-like effect to avoid the situation of intermittent water droplets due to the shutter speed being too fast. 8. ** Portrait at night ** - Get on the tripod, adjust the white balance (automatic or custom), set the USB to 100 - 400, use the Av gear, aperture f8, use the slow sync flash and rear curtain flash mode, and practice the use of the flash and the parameters in the portrait shooting at night. ** 3. Practice from composition ** 1. ** Follow the principles of composition ** - When shooting, follow the composition principles of symmetrical, proportional, diagonal, size, and so on. Practice how to organize the picture. For example, when shooting the classic camera position of Qianhu, shoot from a distance with telephoto. Use the pincushion-shaped distortion of telephoto to compress the space and arrange a person as the visual focus to practice the composition skills in a specific scene. 2. ** Prominent main body ** - Make the photo have a clear and distinct theme. Whether it's a person, still life, or an event, it must be clearly expressed. Focus on the subject, eliminate or compress the elements that can't support the subject and distract attention. Through this method, you can train your grasp of the subject's prominence and the simplicity of the picture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Using a DSLR time-lapse photography
Time-lapse photography with a DSLR required early planning, parameters setting, shooting techniques, and post-production. ** I. Pre-planning and preparation ** 1. ** Choose a theme and plan ** - Decide on topics that have obvious dynamic changes, such as cloud movement, sunrise and sunset, urban traffic, construction, or plant growth. - The estimated total shooting time, the estimated number of shots, and the required shooting interval were calculated based on these. For example, if you wanted to record changes of a specific duration, the shooting interval was determined by the multiple of the number of frames played per second. 2. ** Equipment and accessories ** - ** Cameras **: Choose a digital single-lens reflex camera with manual mode and B-door (long exposure) function. - ** Shot **: Choose the focal length according to the shooting theme. Wide-angle lenses were suitable for shooting large scenes, and telephoto lenses were suitable for compressing the sense of space. - ** Tripod **: The tripod must be strong and stable to ensure that the camera remains motionless throughout the entire shooting process. - Shutter release or remote control: It is used to reduce the vibration caused by touching the camera, so as to accurately control the shooting process. If the camera did not have an interval shooting function, it could be connected to an external smart timer. ** 2. Setting the parameters ** 1. ** Shooting Mode ** - ** Manual Mode (M)**: This mode can ensure that the exposure parameters are consistent throughout the entire shooting process. - ** Aperture priority mode (A-grade)**: When the light changes greatly, the camera will automatically adjust the shutter speed when the aperture value is fixed. 2. ** Exposing parameters ** - Aperture: Usually choose a smaller aperture (such as f/8 - f/16) to obtain a larger depth of field to ensure that the front and back scenes are clear. However, it was also necessary to pay attention to the dust marks on the lens and CCDs and the light refraction problems that may be caused by the smaller aperture. - ** Shutter Speed **: Choose according to the scene dynamic. For example, the daytime scenery could be set to more than 1/60 seconds, and the starry sky delay could take a few seconds or even longer. - ** Iso-level: Set it to a low value (such as 100 or 200) to reduce noise and maintain fine quality. When the light is insufficient, it can be increased appropriately, but you must pay attention to controlling the noise. 3. ** Shooting interval settings ** - Activate the camera's interval shooting function (if available). Setting the shooting start time to 3 - 5 seconds can eliminate the effect of camera vibration when the shutter is pressed. The shooting interval was calculated according to the expected final playback speed and shooting time. It usually ranged from 2 to 30 seconds, depending on the speed at which the scene changed. For example, if you want to play 24 frames per second, the shooting interval should be a multiple of 1/24 second. ** 3. Shooting Techniques ** 1. ** Stable ** - ** Lock tripod **: Make sure the tripod is stable. If necessary, use a heavy object to increase stability, especially in windy or uneven environments. - ** Windproof measures **: Use the tripod head's damp or install additional windproof plates to reduce the impact of wind on the camera. 2. ** Focus and composition ** - ** Manual Focus **: Focus on the point of interest in advance. Turn off the autofocus after locking the focus to prevent the focus from drifting during the shooting process. - ** Fine composition **: Carefully arrange the elements of the picture, considering the movement trajectory of the dynamic subject and the relationship between the background and the background. 3. ** White Balance and Color ** - ** Fixed white balance **: Set manual white balance or custom color temperature to maintain the color of the entire sequence. - ** Shooting in raw format **: This allows for more detailed adjustment of white balance, exposure, etc. in the later stages. 4. ** Storage and Power ** - ** Ample Memory Card **: The card capacity is guaranteed to be enough to store all the photos, and a high-speed card is used to reduce the write delay. - ** Spare battery **: Since time-lapse photography takes a long time, carrying a spare battery can prevent interruption. ** 4. Post-production ** 1. ** import and sort image sequences ** - Use a video editing software (such as Adobe Premiere Pro, Final Cut Pro, etc.) to import the photos, select the "image sequence" option, and the software will automatically arrange them in time order. Set a reasonable frame rate according to the shooting interval, such as 24fps, 30fps, or higher. 2. ** Adjusting and Stabilizing ** - ** Color correction **: Unify the color of the photo, and perform tone map and contrast adjustment as needed. - ** Stabilize the image **: If there is any slight movement during the shooting process, use the stabilization function of the video editing software to correct it. 3. ** Editor and output ** - Cut out unnecessary opening and closing parts, and add elements such as transition and music according to creativity. Choose a high-quality programmer (such as H.264), set the appropriate bit rate and resolution, and export the final time-lapse video. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Using photography to tell a story: Tips and techniques?
One tip is to focus on a central theme. For example, if you want to tell a story about a day in the park, center your photos around the activities there like people picnicking, children playing, and dogs running. Another technique is to use sequencing. Take photos that can be arranged in a logical order to convey the progression of the story, like a series of a flower blooming from bud to full bloom.
