vignette when i make it in after effects i use a very very dark brown layer and set the layer blending to multiply and to 75%
for the chromatic abberation i use the same layer as a basis.
DOF is to be used very carefully so it doesnt look like a miniature.
chromatic aberration is difficult to hit right. most of the time i make it so tiny that it almost doesn't change anything but you kinda "feel" it
sometimes a fake cam shake(not a real shake but a small noise so it kinda "wobbles" more realistic like a shoulder cam
sometimes some bokeh particle(i can not stress the word SOME enough
all those effects have to be used very carefully if you overuse it you can even make a real scene look like its fake
(which could be a nice effect too )
