Camera+, the only 3rd-party camera app that I use, is now available for the iPad.
While I highly recommend that you do not take photos with your iPad in public (in your house is fine), tap tap tap has added a remarkable feature in which Camera+ now syncs the Lightbox photos over iCloud.
I usually deploy Camera+ as my go-to camera during vacations. It would be nice to save some battery life on my phone by doing the editing on the iPad once they sync via iCloud.
On top of that, there a lot of new features including:
Blending of multiple effects
Layer masking of effects
White balance adjustments
Download it now while it's on sale.
