Here are three photos from my new book, "David Hume Kennerly On the iPhone," that is coming out this fall. The project is my attempt to share a bit of what I've learned in my decades of being a professional photographer in the hope of passing along some of my techniques so that others can take better pictures. Another goal is to help people see things in a fresh and different way. By using only the iPhone, a device millions of us carry with us at all times, I demonstrate just what that little baby can do!
