I think you're asking how to edit them? Adjust the lighting effects, etc?
I can't help you there, I've never done it. But I can tell you you need to have a basic editing program, and asking for help from the guys who do this type of editing would be your quickest route to success.
Go right to the Screenshots section of the forum, an do a search for a basic how-to thread, or ask to be pointed toa how-to thread, or ask for pointers from the guys who hang out/post stuff in there.
This is a good place to ask for help (Help and Training), but for something specific like this I'd ask in there. Guys who have a lot of interest in that facet may not have an interest in this section, so may not check in here to answer questions... They may, but may not.
