I had a lot more to submit since I mostly take portraits of the people (and animals) I love, but I didn't want to inundate the forum with my pics. All were taken with Camera Awesome, Camera+, Darkroom, and native iPhone 4s camera. Some were edited using Instagram, HDR FX, iQuick Splash, Snapseed, PS Express, or some combo of those applications.
I've been playing around with the apps, trying to find my groove and/or favorites, but mostly I just end up using certain ones depending on situation. Camera Awesome has several layovers for framing a shot, Camera+ zoom is unmatched; they all have their merits. Don't even get me stared on all the editing apps I use. I swear I'd get an iPad just to photostream my iPhone shots and edit them on the larger screen.
