Ominous Clouds

I upgraded to an iPhone 4 this week and have been experimenting with various camera apps.  The apps fall into one of three categories: camera settings, editing, or sharing.  As a minimalist in editing I'm most interested in the camera apps.  Pure Shot app has some good features like exposure lock which allows a high contrast scene like this to be recorded.  It also has in phone instructions.
