In having so much fun with the Phone Photography Project over at Big Picture Classes. I already use my phone for photography a lot, and I've probably done most of the challenges suggested at some point. That nearly put me off, but I'm so glad it didn't. I have used my camera more, taken more thoughtful images and shared more of them.
On the other hand, I'll have to increase my app budget at this rate! I'm clearly enjoying PicTapGo, A Beautiful Mess and Squaready.
