Photographic dimming lampThe dimmer was a lamp used to adjust the light during photography.
In different shooting scenes, the brightness, color temperature, saturation, and color rendering of the lights needed to be adjusted. For example, when shooting a person's posture, these attributes of the light would affect the image effect, and the dimming lamp could meet the needs of these different scenes.
In terms of functions, some photographic dimming lamps had many characteristics. For example, some photographic dimming lamps had 36000 colors, which could achieve LED full color fill light, could carry out 5 - 100% infinite dimming, and the output brightness could reach 1300 LM. There were also 12 dynamic light effects to simulate common scenes. The body was made of aviation aluminum, which had high strength quality, and the cold and warm color temperature could be adjusted from 2500 K to 6500 K. It supported dual power supply mode, and the power supply could be disassembled.
For example, the Zhiyun 5x M20C had a large color temperature adjustment range of 2500K-10000K, supported HSI fine dimming, and had built-in 10 creative light effects and 6 kinds of LED ambience light effects. It also had corresponding designs in terms of usage, heat dissipation, expansibility, and battery life to meet the needs of creators. In addition, the SP7103 LED driver chip uses the conversion simulation dimming technology, which can avoid the stroboscopic situation of the photography lights. The chip can be connected to the intelligent dimming module to adjust the color temperature and brightness.

DSLR dimming parametersAccording to the available information, the dimming parameters of the Silver Swallow SY-28As flash for the Sony-grade single-lens reflex were mentioned. The flash control had two automatic apertures, F2.8 and F5.6, and the flash index was 28 (100, 50mm focal length). However, this was only the dimming parameters of the specific flash. Generally speaking, the dimming of an DSLR camera was related to parameters such as aperture, shutter speed, and sensitivity. The aperture size directly affected the amount of light entering. A large aperture would enter more light, and a small aperture would enter less. A slow shutter speed would allow the light to enter longer, and a fast shutter speed would allow the light to enter shorter. The higher the sensitivity value, the more sensitive the camera was to light. However, high sensitivity might bring about an increase in noise. Under different shooting scenes and needs, these parameters needed to be adjusted to achieve the appropriate dimming effect. For example, when shooting portraits, a larger aperture (such as F1.8 - F5.6) may be used to obtain a shallow depth of field to highlight the main body of the character, but pay attention to the accuracy of the focus to avoid losing details; when shooting scenery, a small aperture (such as F8 - F16) may be used to ensure a larger depth of field to make the whole picture clear.

Nikon photography dimmingThere were several ways to adjust the brightness of a Nikon camera:
1. ** Exposure-compensation function **: You can adjust it by rotating the dial on the camera or pressing the combination key. If the photo was too dark, increasing the exposure compensation value would make the photo brighter, and decreasing it would make the photo darker.
2. ** Adjusting the sensitivity of the camera to the light **: Increasing the sensitivity of the camera to the light will make the camera more sensitive to light and allow the camera to take brighter photos in dark environments.
3. ** Adjusting the amount of light entering the lens **: Increase the aperture, reduce the shutter speed, and increase the USB parameters to improve the amount of light entering the lens and solve the problem of the photo being darker.
4. ** Method of adjustment in M mode **: If you shoot in M mode, you can increase the exposure time (turn the dial wheel to increase the shutter time, but you have to consider the safety shutter and the target's movement speed), increase the aperture (press the +/-key and turn the dial wheel at the same time), and increase the sensitivity (use the USB button on the left) to increase the brightness of the image.
5. ** Color optimization and correction **: This was an image processing technique that adjusted the sharpness, clarity, contrast, brightness, saturation, hue, and other parameters of the original image. Nikon cameras provided four kinds of correction methods: low saturation correction for portrait shooting, high contrast or high saturation correction for landscape or normal shooting, normal shooting, and black and white correction. Among them, Dynamic D-Lighting (automatic brightness optimization) could automatically adjust the brightness of the screen in a bright environment. It could also brighten the shadows and dim the highlights to retain more details. It was recommended to set D-Lighting to automatic or standard mode.
6. ** Adjusting the brightness of the LCD screen **: Enter the setting menu (with the wrench icon) with the MENU button, find the option of "Liquid Crystal Monitor Brightness" or "Liquid Crystal Monitor Brightness", enter the option and adjust it. However, increasing the brightness will affect the contrast of the playback image, so it needs to be adjusted appropriately.
7. ** Adjusting the EV value (exposure compensation)**: Nikon DSLR usually has a shortcut key marked with a positive and negative sign behind the shutter button. Press and hold it, adjust the main dial to increase or decrease the EV value. You can check the adjustment range on the shoulder screen or LCD.+ represents increment, -represents decrease. The adjustment step size is usually 0.3EV. When you take a new shot, you have to reset the EV value to zero.

What's going on with the screen dimming when reading e-books on my phone?There could be several reasons why the screen of a mobile phone would turn dark when reading an e-book:
1. The default screen brightness of the e-book was different from the brightness of the phone. It could be set in the " settings " menu.
2. If you use a Vivo phone, it will generate a certain amount of heat during use. When the surrounding temperature is high and a large program is running, the heat will be more obvious. In order to prevent the temperature from rising, the built-in protection function of the phone would automatically reduce the brightness of the screen to reduce the power consumption of the phone, thereby reducing heat generation and ensuring the safe use of the phone. After the temperature dropped, the screen brightness would return to its original level.
3. It might have turned on the automatic brightness adjustment, but it could be turned off in the phone settings.
4. The e-book software had a night mode that could be changed in the settings menu of the e-book software or the brightness of the e-book software itself.
