I only know how to work with a render. I don't really know how to work with a stock because I don't know how to make the focal...pop out? I'm used to making a background, and slapping a render on. (not exactly how it goes but you get the point)
Also some lighting tuts? :\ I don't know any good methods with making a good light source and applying it to my sig. Thanks for the help if you gave it.
