Photoshop plug-ins for retouching

Quick introduction

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.

Basic controls

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.

Professional controls

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

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.
