Thanks, Gus. The pictures of your layout that I've seen look great, but if your camera allows it, there should be an option called "White Balance" which will allow you to select the type of available light that you're shooting in. My camera has "Auto", "Daylight", "Tungsten", and "Fluorescent". Selecting "Fluorescent" allows the camera to automatically compensate for this type of lighting, which otherwise gives photos a greenish cast. I think that "Auto" will also do this, but on my camera, it also activates the flash, which I don't want.
