Vignetting is a common problem in photography that occurs when the corners of an image are darker than the center. This can be caused by a variety of factors, including the lens used, the aperture setting, and the distance to the subject. Vignetting can be distracting and can make an image look unprofessional.
There are a number of things photographers can do to avoid vignetting. One is to use a lens that is designed to minimize vignetting. Another is to shoot at a wider aperture. This will help to keep the corners of the image brighter. Finally, photographers can also move closer to their subject. This will help to reduce the amount of vignetting that occurs.
