This plug-in lets you quickly fix vignetting.It also gives full control over the hot spot as well as radial exposure and radial brightness (radial density).This is the Vignetting plug-in’s control panel. Click on the image for a larger view.It works with the following image modes:8 & 16 bit/channel: RGB, CMYK, Grayscale, Duotone, Lab.
Corner correction determines how much the corners are to be raised in exposure.
Corner size determines the size of the vignetting from the corner inwards.Logarithmic - linear determines the nature of the graduation of the dark corners.

These may seem a bit daunting at first, but they are simple enough once you become aquainted with them.
Center (Hot spot)
Professional photographers know that not only may the corners be darker, but there may also be a peculiar radial brightening of the center, know as the hot spot.
Radius sets the radius of the hot spot (overexposed center) in percent of the size of the image.Logarithmic - linear sets the nature of the radial fade-out of the retouch.Exposure and Brightness do what they say.
Radial density is an expression for how the exposure and brightness might fade out or grow from the center to the corners of the image.This part of the control panel lets you retouch this.
Example - hot spot
This image clearly has a hot spot.We fixed it with the hot spot controls in the image to the right.
