What is Color Spotter? Basically, it's contrast, but "centered" around a color. Another way to see it is as another "Color selection" tool: you specify an image, a kind of threshold, and it selects color that are close to the one you specified; only, Color Spotter keeps every pixel from the image, darkening the wanted colors, brightening the others.  read more »

This script helps fix overblown areas of an image. It's not as good as some other methods that must be done manually, but it's not bad. It will NOT fix clipped colors (maximum overblown areas); it only helps increase the contrast in bright highlights.

The script is located in "<Image> / Script-Fu / Enhance / Fix Overblown"

FX-Foundry/Photo/Enhancement/Maximize Local Contrast... Like Stretch Contrast, but instead of using the minimum and maximum pixel values from the entire image, uses the minimum and maximum in the vicinity of a pixel to compute its new value. Takes a while to run, but really brings out textures. Result is a Grain Merge layer that adjusts values of the original image.

This filter operates on the visible image, not on a layer or selection.  read more »
