I found getting guidies/friends to sit still for 10 seconds for me to get a good screenshot is nearly impossible, much less get them in front of nice looking background at the right angle in the right pose. -IF- I get them to actually go somewhere specific for a screenshot I generally take them to the brightest zone we're close to, usually marus seru or stillmoon temple. My computer takes very dark screenshots so the brighter zones make for much less color manipulation after the fact. I cut out the toons and place them on pretty backgrounds.. I have over 3000 screenshots that are just backgrounds, sorted into zones. If I get someone to pose I usually take 20-30 pictures to make sure I get one at a good angle and light.
I'm in the process of teaching myself to use DAZ and then Maya... hard to do Vanguard pics when I can't take screenshots.
