“5 Tips For Making Great iPhone Photos” by Chase Jarvis has a few quick tips for getting better pictures out of the little camera on your Apple mobile. Some of them are pretty much common sense: hold the camera still, and avoid both fast-moving subjects and low light situations.

What really got my attention is Chase’s point #2: compose the shot with your finger on the camera button. I was completely unaware that one could hold down the shutter button on the iPhone camera. The phone does not capture the frame until you let go. This tip should do wonders for sharpness — tapping the iPhone camera’s shutter button is almost guaranteed to introduce a little bit of blur from camera shake. RTFM indeed.
