If the name alone doesn't intrigue you, here's the gist of CameraAwesome: It's a free app that's racked up more than 4 million downloads in the first half of 2012 by offering a simple "awesomize" button to auto-adjust images. Camera Awesome does more than that: It offers quick tap controls for independently adjusting exposure and focus, 36 presets, filters, frames, crop and rotate tools, and compositional aids for framing shots. The video recording app even starts working before you press the shutter button to capture the previous five seconds of action. Useful, if you're a tad slow on the draw.
So how does Camera Awesome make money? In-app purchases. They offer loads of additional filters in packs of nine for $1, or all 250-plus filters for $10. Filters can be mixed and matched to create different visual effects. Camera Awesome's sharing center features all the usual suspects of social sharing, including Instagram, and by picking a favorite service, you can automate the process to get photos on the Web as quickly as possible.
