For the millions of us who have a seriously sophisticated camera that’s masquerading as an iPhone, we owe it to ourselves (and whoever we share our pics with) to up our photog game. I will get you started by sharing the title of a solid resource: The iPhone Photography Book, by Scott Kelby.
Several factors work together to make this book useful and enjoyable. Each of the 200-plus tips is on a single page, each is easy for us amateurs to understand, and each is accompanied by a helpful image. This is a book I consumed in small bites, and I’m keeping handy for quick reference.
The iPhone Photography Book has sections that include camera basics, composing, posing people, travel and landscapes, and editing. It also covers apps and accessories that can enhance your photography even more, although I haven’t yet graduated to that phase.
