From "The Art of Seeing" to "Ultimate Digital Photo Quality," Derek Doeffinger has written and edited over a dozen how-to photography books and three photo books about upstate New York.
He enjoys exploring the creative aspects of photography and has spent the past two years defining the many ways you can use shutter speed to create eye-grabbing pictures.
When he's not taking pictures, he's thinking about taking pictures. His favorite photo subjects include waterfalls and rodeos.
If you're out taking pictures and see a middle-aged guy taking a picture while running the street, give him a shout.
