Just what you need: another iPhone photography app from the SmugMug people:
The app is free and has some great features. I’ve just begun to shoot with it, but I’m hoping to do a video review and/or tutorial showing it off. There are filters and presets that can be purchased inside the app, but Camera Awesome ships with some really tasty filters and effects. The post that will follow this one will show an image or two shot with Camera Awesome.
