#define USE_VIGNETTE 0 //Darkens the edges of the image to make it more look like it was shot with a camera lens. May cause banding artifacts.
#define USE_DITHER 0 //Applies dithering to simulate more colors than your monitor can display. This lessens banding artifacts (mostly caused by vignette)

//I think the shader itself works, but the default settings need a lot of work. Maybe you can find some good settings?
