This Book is a Hit! . I am returning to the market after several years in the motion picture industry and was looking for a refresher on the business end of photography.    Vik Orenstein has provided a wonderful primer for both beginner and professional alike, and I unreservedly recommend this book to anyone who is serious about pursuing a career in photography.    She thoroughly covers necesary subjects such as choosing CPAs and lawyers, networking, and the various photographic markets available for pursuit. She does all of this in a winsome way, relating both her successes and failures as she developed and grew her own studios.    If you are considering entering the field of photography as a professional, seriously consider purchasing this book. You will be making a very wise investment
