exposure poem

What you want to ask might be "photography exposure". In layman's terms, exposure was the amount of light a photo received. Too little light would cause the photo to be under-exposed and dark, while too much light would cause the photo to be over-exposed and white. The exposure was controlled by the three elements of aperture, shutter, and sensitivity: 1. Shutter: The slower the shutter speed (the longer the shutter time), the greater the amount of light entering, and the brighter the photo. Conversely, the faster the shutter speed, the smaller the amount of light entering, and the darker the photo. For example, a high-speed shutter was suitable for capturing fast-moving objects and could freeze a clear picture, while a low-speed shutter could record the trajectory of motion and was used to capture silky water and star trajectories. 2. Light sensitivity: The higher the sensitivity (the more sensitive the camera is to light), the greater the amount of light entering, and the brighter the photo. 3. Aperture: When the sensitivity is constant, the aperture and shutter are in inverse proportion. In addition, there were different ways of exposure: 1. Average exposure method: - The exposure was based on the average light measurement value. The subject was taken as a whole, and the average brightness value of the whole was measured at one time and exposed according to this average value. If the subject has a single tone and the brightness is close to medium gray, or if the subject has a difference in light and dark but the light and dark are evenly matched, a better exposure effect can be obtained. However, when the subject is too bright, too dark, or the light and dark area is too wide and the contrast between light and dark is too large, exposure errors may occur according to the exposure recommended by the light meter. - The average value exposure was to measure the local brightness values of the bright and dark parts of the subject, then average several values, and then expose according to the average value. 2. Regional exposure method: The reflection rate of the scene, the brightness of the scene, the amount of exposure, and the brightness of the image were integrated into 11 gray-scale regions. Level V was the area corresponding to an intermediate gray (18% reflective) object. It was the benchmark for light measurement and exposure. The real areas that could express texture were the seven regions from Level II to Level VIII. 3. High-profile exposure method: It is suitable for the subject to be a bright object with high reflective rate, or most of the subjects are high-brightness objects, such as white, light-colored porcelain, glass, white cloth and other creations, as well as natural scenery such as clouds and snow. The method was to directly measure the brightness of such high-brightness objects, and then increase the exposure by about 3 levels during the exposure, so that the brightness of the image of the bright object fell in the position of Zone VIII. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were many kinds of exposure on the Internet. On the one hand, some micro-merchants were exposed for violating the rules in their operations, such as selling fake and inferior goods. For example, the owner of a fruit shop in Zhangjiagang City, Jiangsu Province, was found and punished by the Market Supervision Bureau for selling N95 masks without packaging, implementation standards and product qualification certificates in WeChat circle of friends. On the other hand, some of the business models in the micro-commerce industry were also controversial and exposed. For example, some micro-business teams had agency relationships and prices were not transparent. Some people questioned that some micro-businesses 'so-called "leading others to make money" was actually relying on lower-level agents to achieve their own wealth freedom. For example, Brother Lu and Aunt Lu's skincare brand was accused of not having a physical factory and relying on processing and branding production. There was also the problem of confusion between agency prices and sales prices, which caused controversy. In addition, in the development process, the micro-merchants also faced the supervision of the industrial and commercial tax departments. Some large-scale micro-merchants may be investigated for suspected pyramid schemes and other issues. Some of the founders of the micro-merchants were taken away for investigation due to law enforcement in other places.

Over-exposure to comics had many effects. On the positive side, comics could make people feel relaxed. But from a negative perspective, the situation was complicated. For high school students, studying was their top priority. Over-reading comics, especially if they were addicted to them, would cause a lot of harm. Firstly, it would affect one's enthusiasm for learning, making it difficult for one to focus on their studies. As time passed, it would inevitably lead to a decline in their grades and even cause them to be disgusted with their studies. At the same time, they might use comics as an outlet for their emotions, which would not improve their ability to express themselves and their practical communication skills. It might also affect their rest at night, causing them to be in poor condition in class the next day, which would further affect their studies. In addition, some vulgar comics would have a negative impact on the physical and mental health of high school students. From a broader social perspective, comics, as a cultural product, had an impact on society that could not be underestimated. The ideas that some comics spread may affect the values of readers.

If the photo was exposed, there were several ways to adjust it: - In the camera, you can choose to increase or decrease the sensitivity to restore the exposure. You can also control the dynamic range of the photo, film simulation, and choose the appropriate grain effect to simulate the film texture. You can also strengthen the adjustment of color effects such as red and blue. - If you use your phone to adjust, you can press the following parameters: exposure +100, sharpness +73, highlight-62, shadow +67, contrast +20, brightness +19, black dot +9, saturation +11, natural saturation +26, hue +11, sharpness +11, clarity +8, noise reduction +6, halo +30, and then return to reduce the exposure to +13. - If you use ps software, under the raw format picture, check the delete color difference and use the configuration file correction in the optical module. In the geometry module, correct the horizontal and vertical. In the basic module, for overexposed photos, first lower the highlight and white to the left. If it is still too exposed, lower the exposure to the left. After adjusting the black and shadow according to the above, adjust it to the left. When the picture is foggy, the mist removal function can be improved. If you want a soft picture, you can lower the texture. If you want a clearer picture, you can raise the definition. Then, you can adjust the highlight shadow above according to the needs. You can pull the natural saturation to 10 - 15, the saturation below 10, and the contrast between-10 and-20. In the color mixer, if some colors in the picture are too bright, you can lower the brightness. If you want to highlight the color, you can raise the brightness. The saturation is generally lowered and the hue can be adjusted. - If you use Meitu Soo Soo, you can reduce the degree of overexposed by brightness adjustment. If the overexposed area is concentrated in some areas such as the sky, you can cut out these parts. You can also use the smart repair function to automatically identify and repair the overexposed area. If there is noise, use the noise reduction function.

DSLR time-lapse photography exposure involved the following aspects: ** 1. Shooting mode and exposure parameters ** 1. ** Shooting Mode ** - ** Manual Mode (M)**: It can ensure that the exposure parameters are consistent throughout the entire shooting process. It is suitable for scenes with relatively stable lighting. - ** Aperture priority mode (A-grade)**: This mode is suitable for situations where the lighting changes greatly. The aperture value can be fixed, and the camera will automatically adjust the shutter speed. 2. ** Exposing parameters ** - Aperture: Usually choose a smaller aperture (such as f/8 - f/16), which can obtain a larger depth of field and ensure that the front and back scenes are clear. - ** Shutter Speed **: Choose according to the scene dynamic. For example, the daytime scenery can be set to 1/60 seconds or more, and the starry sky delay may take several seconds or even longer. - ** Isofile **: As low as possible (such as Isofile 100 or 200) to reduce noise and maintain fine image quality. When the light is insufficient, it can be increased appropriately, but you need to pay attention to noise control. ** 2. Compensation for exposure in special scenes ** 1. ** High-light scenes (such as snow, white beach)** - The camera would underestimate the brightness, resulting in insufficient exposure. You need to use positive compensation (increase the exposure). For example, when shooting snow scenes, you might use a positive compensation of +1 EV to make the snow look whiter and brighter. - Metering mode can be selected to evaluate the measurement. For example, the shutter speed is 1/250 seconds, the aperture is f/8, and the exposure compensation is +1 EV. 2. ** Darkened scenes (e.g. black background, night)** - The camera might overestimate the brightness, causing the subject to be overexposed. Negative compensation (reducing exposure) should be used. For example, when shooting a city street at night, negative compensation of-1 EV should be used so that the background is not exposed and the main body is exposed. - For example, the parameters were: Metering Mode Evaluation Metering, Shutter Speed 1/60 seconds, Aperture f/2.8, Iso1600, and-1 EV exposure compensation. 3. ** Backlight Shooting (Main Body Backlight)** - The camera may not expose the subject due to the high brightness of the background. Positive compensation was required. For example, when shooting a backlit portrait, a positive compensation of +1 EV was used to ensure accurate facial exposure. - It can be used in spot measuring mode. The parameters are: shutter speed 1/200 seconds, aperture f/4, USB 100, exposure compensation +1EV. After measuring the light, the camera will be re-composed. 4. ** High-contrast scenes (such as scenery shot against the light)** - The camera may have difficulty balancing the exposure of the highlights and shadows. Use positive or negative compensation as needed. For example, when shooting a backlit landscape, use a positive compensation of +0.7 EV to ensure that the subject's exposure is moderate while retaining the details of the highlight. - It can be used in the spot measuring mode. For example, the shutter speed is 1/250 seconds, the aperture is f/8, the CPU is 100, and the exposure compensation is +0.7 EV. After aiming at the subject, the camera will be re-composed and shot. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were many applications for camera exposure in photography: * * 1. Affects the image quality and effect ** 1. * * Correct exposure to ensure image quality ** - The correct exposure was the basis for a high-quality image. In photography, the amount of exposure was directly related to the clarity of the image. If the exposure was correct, the sensor could accurately record the brightness, color, and other information of the scene, so that the photo had rich layers, clear details, and accurate color reproduction. - For example, when taking landscape photos, the appropriate exposure could make the sky, mountains, trees, and other parts appear accurately. It would not lose the details of the highlight parts due to overexposed (such as the sky becoming white and the details of the clouds disappearing), and it would not lose the details of the dark parts due to insufficient exposure (such as the trees in the shadows becoming black and the trunk and leaves could not be distinguished). 2. * * The artistic effects of overexposed and under-exposed ** - Sometimes, for the sake of artistic expression, one could deliberately overexpose or under-expose the photos. For example, when shooting some abstract or dreamy scenes, appropriate overexposed could create a bright and ethereal atmosphere, while underexposed could be used when shooting low-key portraits or mysterious scenes, emphasizing the main body or creating a specific emotional atmosphere by letting part of the scene be in the dark. However, even if it was for the sake of artistic effect, it was necessary to control the degree of exposure to ensure that it did not affect the theme and instead added points to the theme. * * 2. Cooperate with photography techniques ** 1. * * Relationship with light sensitivity, aperture, shutter speed ** - The sensitivity, aperture, and shutter speed worked together to control the camera's exposure. When the sensitivity was fixed, the aperture size and shutter speed restricted each other to achieve the same amount of exposure. For example, if the aperture was opened one level (the amount of light entering was doubled), to maintain the same exposure, the shutter speed needed to be reduced by one level (the exposure time became half of the original). This relationship was known as the "reciprocation rate." - In actual shooting, this relationship could be used to achieve different shooting effects. For example, when shooting a moving object, if you want to freeze the moment's movement, you need to increase the shutter speed. However, in order to ensure the same exposure, you may need to increase the aperture or increase the sensitivity accordingly. When shooting a landscape that requires a large depth of field, you can reduce the aperture and adjust the shutter speed according to the "reciprocation rate" to obtain the correct exposure. 2. * * Control of exposure in different shooting modes ** - * * Automatic mode (Automatic)**: The camera controls the exposure. The camera will analyze the scene according to its own light measurement system, and automatically adjust the sensitivity, aperture, shutter speed, and other parameters to obtain the appropriate exposure. This mode is suitable for beginners or for quick shooting in emergency situations, but it may not meet special creative needs. - * * Sequential exposure mode (P)**: Although the camera controls most of the parameters, the user can choose from a set of parameters given by the camera. For example, the camera might give a combination of f/5.6 aperture and 1/125s shutter speed, or another combination of f/8.0 aperture and 1/60s shutter speed. The user could choose according to their initial requirements for depth of field or motion blur. - * * Aperture priority mode (Av)**: The user controls the aperture size and exposure compensation, and the camera will automatically adjust the shutter speed according to the aperture value set by the user to achieve the appropriate exposure. This mode was very useful when shooting portraits, because the depth of field could be controlled by adjusting the aperture, making the character clear and the background blurred, and the main subject prominent. - * * Shutter priority mode (Tv)**: The user controls the shutter speed and exposure compensation. The camera will adjust the aperture size according to the set shutter speed to obtain the correct exposure. For example, when shooting sports events, the photographer could set a fast shutter speed to freeze the movements of the athletes, and then the camera would automatically adjust the aperture. - * * Manual Mode (M)**: User controls the sensitivity, aperture, shutter speed, and other parameters. It was suitable for experienced photographers. They could accurately control the exposure according to their creativity and understanding of the scene to achieve some special effects, such as deliberately overexposing or underexposing. * * 3. Connection with Photmeter Mode ** 1. * * Determination of exposure under different measuring modes ** - * * Rating: The camera will divide the image into several areas for measurement. It is suitable for scenes with relatively uniform light, such as most scenery scenes. The camera calculated a suitable exposure value based on the light conditions of each area to ensure that the exposure of the entire picture was relatively uniform. - * * Central Average Metering **: Metering method with the central area as the main weight. It is suitable for subjects with a clear main body in the center of the picture, such as portraits, racing cars, etc. The camera would focus on the light in the center of the picture to determine the exposure. At the same time, it would also take into account the light in other areas of the picture to make the overall exposure more balanced. - * * Local Metering and Spot Metering **: These two methods only measure light in a specific small area (such as the circle in the picture). They are more suitable for high-light environments, such as backlighting portraits or shooting artifacts. In this case, the photographer could accurately measure the light of the subject to avoid inaccurate exposure of the subject (such as the face in the backlit portrait being too dark or the exhibit being overexposed). - * * Average Metering **: Average the image exposure information on the entire screen to determine the exposure. It is more suitable for outdoor or landscape shooting. It could give the whole picture a relatively average exposure effect, but it might not be accurate in the case of complicated lighting or a large ratio of the main body to the background light. - * * Strong Light Metering (Some cameras have it)**: Focus on the bright areas of the screen to ensure that this part will not be overexposed. When shooting scenes with strong light sources or high-light areas, it could ensure that the details of the high-light parts were preserved. * * 4. Relationship in the retouching of the map ** 1. * * Post-production exposure adjustment ** - During the retouching process, the exposure could also be adjusted. However, when adjusting, you need to refer to the exposure of the main body in the picture, and pay attention to avoid the situation of blooming (the brightest part of the picture becomes white and loses details) and the dark part is dead black (the darkest part of the picture becomes black and has no details). The specific adjustments were based on the specific content of the picture and the desired effect. It required constant practice and reference to other people's works to grasp the degree of adjustment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
