I read a couple of articles, and got some time to play around. I have a Samsung NV3 digital, and can't adjust the F-stop, or shutter speed, or gray scale, at least not from what I see in the manual. The manual is rather useless, though.
I built a quick photo booth, from a busted window blind and an old pillow case. I adjusted the white balance, metering, focus point, and sharpness. This is the best of what I came up with.
