I can use photoshop and create reasonable results, but after looking around here I'm wondering what someone else can do with this screenshot. (Want to use it as my BG.) My attempt involved trying to make it look photorealistic, but I'm just not that familiar with that aspect of photoshop. (Shot is me protecting my lead at the start of the LOTA league sprint race at SO Long going around the outside using every inch of room I could.)
I gave it a quick shot, what i did was made a new layer, then filled the whole picture with a bright orange shade like this one. The I changed the layer style to Overlay and took the opacity right down to around 15-20%. Then i grabbed the original layer with the picture on it and lowered the saturation on the picture slightly, all of that gives it that slight sepia/sun glow effect which looks real. Also i added a shine mark down the right side of your car's nose. Which again added to the sunglow. To me it does now look more realistic, but thats me. You like it? Oh, i added a higher contrast one in there aswel. Simply because i love higher contrast on a picture.
Well, the first one has taken the place of my photoshop as my background. The higher contrast one makes some of the artifacting in the textures show pretty sharply. Seeing these reminds me that I really should work on my own helmet design though, maybe mimic my cheapo HJC auto-x'ing helmet except the design on it is pretty complicated and would be a bitch to line up right.
I like the second one, but it won't edit that well because it looks like the resolution and texture detail as well as AA need to be tweaked. If you can do that, I'll have a crack at an edit.
I did 2 quick edits of the first one. I made it 50% of the size, which sorted out alot of the Anti-aliasing problems, but they're still visible. Nothing i can really do about that in a short amount of time, i just suggest making your graphics settings better when you take the picture, then turning them down after your finished.
