I take portraits. One second the shot has depth and contrast, and the next few frames it's flat, has no contrast, and the skin and eyes look totally reddish. Sometimes it goes away...sometimes it does not. I'm very confused. Attached to this post are examples of a good frame and a bad one. Body: Canon 60D. Lens: Canon 60MM 2.8 Light: Natural diffused, sometimes with Fluorescent Kinos daylight temp Settings (give or take): Shutter - 200 or 250 ISO: 200-250ish Stop - 2.8-3.5 Thanks ya'll!
