Uses one colour for the highlights and another for the shadows.

This Shadow&Highlight script does a decent job of lightening shadows and/or darken highlights in photographs. The UI gives you five control sliders. Two for control of the Shadow and Highlight amount (opacity), two for the tonal width of each contrast mask layer (using gamma), and one for the blur radius of the masks. Plus the option to flatten visible layers when done.  read more »

Turn a boring flat image into a stylish 3D-shadowed-glowing one.

This is a series of Script-Fus that implement various layer effects:

• Drop Shadow
• Inner Shadow
• Outer Glow
• Inner Glow
• Bevel and Emboss
• Satin
• Color Overlay
• Gradient Overlay
• Pattern Overlay
• Stroke

Some effects can have contours (a.k.a. curves) and noise added to them. Effects can either be applied on a separate layer, or be merged into the active layer (which in some cases gives better results).

Tested with GIMP 2.4.2.

• Bugfix

This plugin does a pretty good job of eliminating shadows and highlights in photographs. It gives you two layers that basically act like adjustment layers, and changing the opacity will alter the effect.

Recover image information in dark parts

This script (originally by Iccii) implements the effects: add border, bevel and emboss, color overlay, drop shadow, gradient overlay, inner glow, inner shadow, outer glow, pattern overlay, satin.

It works when applied on a (transparent) layer or on a textlayer, but not on the background-layer . The layers are linked so the object can be moved around.

The latest version is tested on GIMP 2.4.
