Camera+ is by far the best photography app I have found. If you want your iPhone to act like a professional camera, this is the app for you... AND it is currently on sale for $.99 it has sold for as much as $2.99 since it's release.
With it you can:
- stabilize your camera shots
- cure crooked angles
- use up to 6x zoom
- set exposure and focus separately for ultimate control
- use scene modes including portrait, scenery, sunset, night, plus more
- create borders and incredible effects
- crop photos
- ......and much more
You can buy this one app or buy up to 3 others to get the same amazing functionality. This one app has transformed how I use my iPhone camera as well as improve the quality of my pictures. I've said it before and I'll say it again.....buying this app is a no brainer.
