How to reduce Lens Vignetting

Optical vignetting is the darkening of the corners of an image compared to the centre. This light fall-off occurs naturally in all lenses but is only noticeable where the optical design causes the light to travel at angles which cause light loss. Vignetting can also be caused by the use of non-compatible accessories which block light entering the lens.

Try the following to reduce vignetting

  1. Stop down the lens - a lens will show the most vignetting at its widest aperture, so a simple solution is to stop the lens down from the maximum aperture when possible.

 

  1. Use the Vignette control tool in the camera menu - current DSLR cameras have a Vignette control option in the Shooting menu. This can be set to High, Normal, Low and Off to suit your preference and is applied to images until it is turned off.

  1. Capture NX-D Vignette control tool -  can also reduce the effect of vignetting but offers more control than the camera tool and can be applied to individual or multiple images using batch process.

  1. Remove physical obstructions - vignetting can be caused by objects physically blocking the path of the light at the edge of the frame such as stacking several filters together or using non-compatible lens hoods or extensions. This usually causes a black area of vignette in the corners of the image area with very little graduation. Try removing such objects to see if they are the cause of the vignetting.
