DuckShader v0.1 - OpenGL Post-Effect Shader

[amozzz]

I would like it if the deep blacks were lessened a smidge. You want to hit the point where it heightens realism without obscuring too much of a scene.

For example, Twilight Princess ab #2. Notice how native the background path is easy to make out - in this it's almost lost. That has a lot to teach about the brightness cues you might retain.

Then I suspect it will handle not only realistic but cartoon art styles as well. I mean this Mario Kart looks like a bad acid trip...

I look forward to your source implementation.
