Bruce Barnbaum demonstrates methods for both traditional and digital approaches. "The art of photography" is an amazing guide for everyone who loves photography and wants to know more about compositions, filters, light and color, printing and presentation, etc.

The book delves into all of the traditional approaches to composition and design, but it also addresses the new digital technique of shooting with the expectation that the image will be edited, manipulated, or montaged later, resulting in a final image that may be very different from the one seen through the viewfinder.
