vignetting

on the fields dialog box. Clicking on this button will recompute the vignetting factors for each field based upon the current lens data.

5 cameras, 5 sets of vintage vignetting, film scratch, black and white &cross processing effects for that off-the-hip analog look.

Vignetting and distortion are both corrected excellently for a lens of this speed.

If light deviates too far from perpendicular, you get vignetting and other aberrations are exaggerated.

The established model can rejuvenate the input image so as to finally resist vignetting from degradation of camera pattern in a cell phone.

You can then load the second image as a mask and further adjust the effect and brightness until the vignetting effect is reduced or removed.

Vignetting is created either in camera using vignetting hoods or in darkroom by burning or dodging the edges of the image.

Vignetting refers to the lightening or darkening of the edges of an image.

You can see here a thumbnail preview of the anti-vignetting mask applied to the image.

Otherwise, vignetting may occur when zooming out.

Other focal lengths are not as affected but you should still reckon with about 1EV of vignetting here at max. aperture.

The use of micro lenses over the image sensor can also reduce the effect of pixel vignetting .
