Yeah that trick works, but the picture is darker and a lot grainier. Also if you point the camera to a bright light source, it "resets" and then when you point at dark areas again, it lags. That trick seems to "initalize" the camera to a dark setting, for lack of a better phrase.
I wonder if there is a way to make the camera behave that way all the time? I snapped a picture with the trick active and it came out pretty good.
