Why does the iPhone turn on the flash to take pictures and turn white?
The iPhone turns white when the flash is turned on, because the white balance of the flash is too high, which is normal. When taking pictures, the sensitivity of the camera is adjusted too high. Because the sensitivity is too high, the camera will turn white at the moment when the flash flashes. If you take pictures at night, I suggest you reduce the sensitivity, 100~200 or so. Too high sensitivity will cause whitening.
Sensitivity is an index similar to film sensitivity. In fact, ISO of digital cameras is realized by adjusting the sensitivity of photosensitive devices or merging photosensitive points, that is, by improving the sensitivity of photosensitive devices or merging several adjacent photosensitive points. Photosensitive devices have a kind of reaction ability and are fixed. There are two ways to improve the ISO of digital cameras.
