This book is aimed at neither the casual consumer nor the professional digital photographer with $50,000 to spend. Rather, it is perfect for several types of professionals: graphic designers, design students, real estate and insurance agents, and many others. It shows how digital cameras work (what makes both the inner workings and the output differ from that in traditional film cameras); which camera to buy for your needs and budget; and how to take, edit, archive, and store pictures.
A lot of the information and explanations in Real World Digital Photography will still be useful long after the featured cameras are considered yesterday's technology.
