Here, a little window light was just perfect. The subject was far enough from the wall that the light was not as intense back there, creating a natural vignette. at higher ISO's, proper framing in camera is crucial so that you still get the most resolution on your subject. This image has had no post processing, not even cropping; the Kool-Aid mustache is all natural. Nikon D90, 18-200mm lens @ 200mm, f/5.6, 1/40s, ISO 500.
