I take a lot of pix at night with my Olympus D-460L camera and it sux. I get a lot of white bubbles in my pix along with crappy skin tones. So, I'm lookin to upgrade. Whats a good <$800 camera that takes good night time shots? I'd prefer it to be a point-and-click type since I don't know too much about setting up shots with cameras. BTW, any good sites for beginners that explain how to set up exposure, white balance, etc?
