Hello, thank you very much and the answer to your question is yes. Depending on how well screenshot came out aka, lighting, pixeleted edges etc. i always run them through some 30min-1h process of edits per shot in photoshop to boost light, adjust some midtones, shadows, blur edges, fix pixelated details (like in this case the golden roots on his armor are very pixelated around so i smoothed it down and colored over it to match the armor too) . Sometimes i do them by simple dodge/burn tools, but i also work recently with brush aswell to be more detailed and get different effects on it. My goal in the end is to not alter the picture but pull the best out of it in terms of smoothness/color/and tones to have overall pleasant look. But i do make sure to have good filter and settings and in-game hour for taking screenshots because not everything can be worked out after no matter how hard one's try.

I hope this answer helps.
