Inara Pey has an article about a program named Reshade that can be used with Second Life™. The author calls it a post-processing injector for games… Post processing simply means processing an image after it is initially rendered or captured. The injection part is about setting the software up to capture images from your game software, in Second Life’s case: the viewer, by adding software to the viewer.

If you Photoshop images (post-process), I do, then this add-on allows you to do much of what you would do with PS but to machinima/video. I’ll call this software a baby sister to Adobe’s After Effects. It is limited compared to After Effects. But, is a great tool for almost free.
