How to use a Canon camera to take still life photos of Beijing in pure white

Why does it still appear gray when photographed even though the background is white? Let me tell you, you need to do two actions. One is lighting, which means you need to use a light to illuminate the background. But note that the subject you are shooting should be at a certain distance from the background, so that the light will not affect the background. The subject causes glare; the second is that the camera adjusts the exposure, that is, adjusts the aperture and shutter speed. On the premise of ensuring the normal exposure of the subject, increase the aperture value. For example: F8 is a normal exposure, try to adjust it to F5.6 or F4 . Because there is a flash, the shutter speed should be adjusted below 1/160 seconds. Try 1/125; 1/80 seconds. Sometimes the subject may be filled with fill light, but the light should not be too bright, and the details of the subject will be lost after being overexposed.

Your problem is a shooting problem, not a camera problem, so it’s the same for Canon, Nikon and Sony, give it a try
