When I take a picture inside with flash say in a gym or the mall, the pictures are so dark I can't see what I was taking a picture of. If I turn the flash off, the pictures are so blurry that I can't figure out what I was taking a picture of. I tried adjusting the source of light to Tangen, or flourescent, but that made no difference. How can I take a picture in lighting that is not natural, and still be clear? Thanks!!
