Here's the secret to good pictures from my experience....Hawaiian Sunlight! Actually, the best pictures I've found are with a white background and I take them on my windowsill in the late afternoon, so it's not direct sunlight, but it's real light and not inside lighting. The inside lighting tends to give a darker picture and a yellow tinge to it. I just have a Fuji digital camera, no special gadgets or anything. I have told others the same thing and when they tried it they said it vastly improved their pictures. Try it out!
