Camera phones are quite fun to play with. They enable you to take pictures that you otherwise not have taken with a regular digicam due to extreme conditions. These three pictures were taken with my Samsung Galaxy S2, without using a flash. Viewed small, the image quality is surprisingly good. At full size, the pictures are grainy, but not as bad as I thought they would be. Night shooting is certainly a lot of fun with a smartphone.
Another area to experiment with a camera phone is at the snow. A regular digicam would have problem with condensation on the lens. However, I was told buy several people that they have absolutely no such problem with a camera phone. The pictures come out crisp and clear. That will have to wait for another day.
