Why do professional photographers always turn on flash and never shoot continuously?

Actually, this is a problem. Personally, I think that if you don't turn on the flash, the light ratio control and exposure control are inconvenient and you won't be able to achieve the desired effect, and you have to slow down the speed or increase the sensitivity to get the correct exposure. Lowering the speed may result in a blurry image, and increasing the sensitivity will increase the noise in the image. These all result in picture effects. If the flash is turned on, it will take time for the flash to fire and the capacitor to be recharged. About 1-3 seconds, the continuous shooting effect will be black and underexposed. In fact, the continuous shooting effect is not for portraits. For example, animals, sports, etc. are mostly used outdoors.

Yingmei Digital Store said it well. Turning on the flash can fill in light for parts or shadows, and can enrich the details of the picture. The flash requirements for continuous shooting are also relatively high
