Crap, I will my money back. Just kidding ^^. Prior to Sol 1.5 I was using Adam's enhanced filter. With Sol 2.1.3 I've tried this one and it's just PERFECT to me.
All subtle effects are well reproduced and there is an overall natural clarity that plays a lot for immersion. I tweeked contrast and saturation a bit down (2%) in Sol app ingame when using the PHOTO version (just my taste).
Notice that 2 versions <Photorealistic> and <Photorealistic_PHOTO> are provided suiting diffrent needs.
Awesome filter thanks !
