The Art of iPhoneography: A Guide to Mobile Creativity

Quick read and this is very outdated. Initially I thought this was a guide for all iPhone photography but this book came out in 2011 back when the iPhone 3 and 4 was around. If you have an iPhone 5 and up then you can use the tips given with a grain of salt. Also the apps stated throughout the book are outdated as well. I did enjoy discovering new artists though.
