#define USE_HDR 1 // Not actual HDR - It just tries to mimic an HDR look (relatively high performance cost)
#define USE_TECHNICOLOR 1 // Attempts to mimic the look of an old movie using the Technicolor three-strip color process (Techicolor Process 4)
#define USE_TONEMAP 1
#define USE_VIBRANCE 1 //Intelligently saturates (or desaturates if you use negative values) the pixels depending on their original saturation.
#define USE_SEPIA 0
#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 1 //Applies dithering to simulate more colors than your monitor can display. This lessens banding artifacts (mostly caused by vignette)
#define USE_DPX 1 //Unfinished - Should make the image look like it's been converted to DXP Cineon - basically it's another movie-like look similar to technicolor
//I think the shader itself works, but the default settings need a lot of work. Maybe you can find some good settings?
