The Joy of iPhotography: Smart Pictures from Your Smart Phone
Forget all the tech-talk about workflow and archiving, Apple have given us all a camera that takes care of all this for us, so now it's time to take great photos. This book will show you the best ways to approach every possible subject with your iPhone, offering tips as clear and simple as the iPhone's interface. Additionally you'll see some great effects that you won't find in Instagram (but your followers will love).
Jack Hollingsworth is easily one of photography's most well known names, thanks not only to his years experience in World Lifestyle, Travel, Portrait and Stock Photography, but his popular @photojack twitter account.
