I’ve heard some people don’t like the iPhone camera, that it’s not very good, etc etc. Chase Jarvis is a photographer, he owns an iPhone and he takes lots of photos with it. His iPhone photos look all right.
The best camera is the one that’s with you. As such, I take between 1 and 1000 iPhone images every day and share at least one online with the world via Twitter and Facebook. These images are uploaded directly from my iphone, using only native iPhone applications, and no Photoshop whatsoever. This is an ever-changing gallery of my recent favorites.
