Supercharge Your iPhone's Camera. Without further ado, here are the apps:
Adobe Photoshop Express 2.0
Free. Camera Pack upgrade $4.99
Adobe knows something about image editing, and you get a taste of this expertise in this free app. But you'll need the $4.99 upgrade for full app functionality, and you get finer editing controls in Snapseed, and more effects in Instagram and Camera+.
AntiCrop does one thing, but it's an interesting thing: Extend edges of your photos based on existing content. It's not perfect, but for 99 cents, it's a nifty tool for your iPhone photo kit.
A beautifully designed iPhone camera enhancer, Camera+ gives you more shooting options and better image effects than you'll get with the native iOS Camera app. If you need even more image control, opt for Snapseed, and if you need more shutter options and sharing, head for Camera Genius.
More limited than most apps here, CameraBag simply lets you remake your iPhone images to resemble various photographic styles, both retro and striking.
Camera Genius 4.2
Camera Genius adds some cool shooting and post-shot tools, some of which are matched by the slightly slicker Camera+. It's the only app here that can time and place stamp your images. It also lets you trigger the shutter using your voice, a timer, or when the image comes into focus. Camera Genius offers the most direct sharing options we've seen: to Flickr, Facebook, Twitter, Picasa, and Tumblr.
Color Splash does one thing, but does it well. It lets you easily create a striking photo by adding areas of color in an otherwise black-and-white image.
Hipstamatic shares some similarities to how some would characterize hipsters themselves: a lot of style but not much substance. There are much easier ways to get retro effects on your iOS photos and to share them, but the app is cleverly and stylishly crafted, and lets you pretend you're using a Kodak Instamatic from days gone by. One downside is the many in-app purchases are needed for new "gear."
Instagram combines photo effects using a very clever interface with a captivating photo-centric social networking element. Though it only offers square photos, only on the iPhone, you can still share to other social networks, but its own is the real draw.
In a clear, innovative interface, the master of photo correction, Nik, has produced the only iPhone app that approaches the power of desktop digital image editing software. Possibly the most powerful iPhone image-editing app around, Snapseed can do amazing thing with your phone photos, lets you then share them directly to the major social networks.
