Sure there's Instagram and Hipsta-matic. But there are lots of other really great camera apps for your iPhone that will do stuff even the big ones can't, and do them well.
So here are my 5 picks for camera apps to check out.
Of all of the apps that let you easily put text over an image, Over is probably one of the easiest and most beautiful. It isn't the most flexible, but it is flexible enough to handle most the the needs I've ever had. Its fonts and colors and typography controls are such that it has kept me from messing up an otherwise good photo.
If you want to make a photo mosaic on your phone, there are hundreds of apps to choose from. Diptic distinguishes itself for me because of how well it performs (not a lot of waiting), and how easy it is to get my images to look just the way I want, including the ability to adjust the cell size of your mosaics.
This little app is a powerful image editing tool. There was a photojournalist who decided to cover the Olympics entirely with his iPhone and it was Snapseed that he used to make sure his photos fit in with all of the other photos covering the games.
The set of tools include being able to adjust saturation, focal points, tilt-shift, add frames and a lot more. It represents a first real contender to replace the digital photo paradigm we've come to assume was innate.
