Mechanical_vignetting_SDXL版本IL_v1 (ID: 1151534)

Mechanical vignetting occurs when light beams emanating from the lens aperture are physically obstructed by external accessories like filters, secondary lenses, or improper lens hoods. This results in a reduction in brightness or visible shadows at the corners of the photograph. It is most noticeable with wide-angle lenses and wide aperture settings.
