It looked clear on the camera at that time, but it felt dark on the computer. What is the reason? Thank you! ! !

Analysis:

There are many reasons. If it is automatic, try another mode. If it is manual, you can try to extend the shutter time or increase the aperture. Anyway, it is to increase the exposure. It's hard to say without specific circumstances. Did you shoot it in a very bright place? Will be underexposed.
