I think Photoshop would have a nice Depth of Field effect if you managed to get the depth buffer when taking your screenshot. But without it, it would be hard to get a realistic result.
Yeah indeed, I implemented new features in the shaders like height aware exponential fog (Crytek's implementation of it), and some post processing (vignette, tweak to the S-curve). The rendering is also in linear color space (gamma correct rendering, which Scawen is *properly* adding to LFS's next update btw) thanks to Keiichi_Tsuchiya. After that it's mostly stock reshade effects (depth of field and bloom for example).
Yes, I'm sharing them, its just a test.
But they are working only with Rockingham - Clear Sunset and you have to replace Sky_sunset 2c.dds also, if you want a brighter sky you have to go to Options -> Graphics and set "Draw sky" to off. Remember to backup the original files.
I'm editing this part of Cars2.psh if you want to tweak it:
