iPhone application Snapture may be limited to jailbroken iPhones, but if you’re willing to go to that effort, it can make some major improvements to your iPhone’s photographic abilities.
Features such geotagging and a delay timer give an iPhone the functions necessary to at lease match a point-and-shoot camera. But Snapture goes so far as to provide photographers with a little basic editing capability on the go. While few professional photographers are going to change over to the iPhone as a main camera, Snapture does extend its abilities enough to make it a useful tool for an amateur photographer.
