Great looking filter, one of the best for screenshot by far and even for gameplay it looks really good.
My only problem with it is that in photo mode the depth of field doesn't work really well (it's waaay less blurry than it should be with some combinations of f stop and focal length), so I fixed it creating a copy of the post FX script and pasting these values from another post Fx:
[DOF]
ADAPTIVE_APERTURE_FACTOR=0
APERTURE_BACK_LEVELS_NUMBER=7
APERTURE_FRONT_LEVELS_NUMBER=7
APERTURE_F_NUMBER=11
APERTURE_PARAMETER=2
APERTURE_SHAPE=6
BACKGROUND_MASK_THRESHOLD=0.02
BASE_FOV=70
EDGE_QUALITY=4
ENABLED=1
IMAGE_SENSOR_HEIGHT=0.35
QUALITY=5
I suggest others using this script to give it a try, apart from this no other issues found.
