Wondering what people think, or what you do yourself and why, stick any I may have missed in.
Screen space reflections - havent done them, not sure where, close to start?...
Eye Adaptation - builds info probably done early?
Lens flare - get it in before bloom?
Bloom - before dof ??
DOF - you want the bloom 'under' it?
FXAA - you want to AA toward then end right?
Color Correction - want final color, before correcting...
Tone Mapping - fit for ldr
Gamma Correction - correct for screen output
Vignette - because its just black on top of everything else...
