Im not keeping this secret anymore it really does make the biggest difference. When shooting anything with delicate colors ( ie leo's) use a 50% gray background instead of pure black,white or a solid color. There are 2 reasons this makes such a dramatic difference . 1. Neutral gray helps your eye focus on colors with in it. 2. Neutral gray is very friendly to your camera's automatic meters. So try it out and show your love. pce.
