Here are some of the iPhone Apps that I use most:

Slow shutter – I use this when I want to do pans or swipes with the iPhone.


HDR – This has been my primary app for shooting HDR images.


Pic Grunger –  I use this for creating down and dirty grunged or aged images.


Hipstamatic – When I want to create retro looking images. A camera with built in post processing effects.


 Autostitch – When you want to capture a panoramic.
