Hi all,

I am wondering, what is the best (most performative and good results) way to apply some basic graphic manipulations like Brightness, Contrast, Noise etc. to a rendered image in OpenGL?

Thanks!

Using GLSL (shaders).
GLSL can do this faster and nicer then Java2D

On that note @deepthought, I've always wondered whether your name is actually a reference to Douglas Adam's Hitchhiker's Guide...?

Probably the name is from the famous computer that could play chess very well?
