Hi all. I have been taking photos with a Canon Powershot A80 in a small setup with a white background. Usually, my photos will turn up to have small black shaded gradients at the corners which I have to manually remove it in PS.
In some photos, the black shaded regions can get darker.
Is this normally due to the limitation of the camera, bad lighting or any other reason?
This is an example (only did resize in PS)
