Bokeh is a new kind of book about cameras designed for the iPad that contains lessons on FOCUS, DEPTH OF FIELD, EXPOSURE, and ZOOM.
Each lesson simulates the photographic process on a real scene as you interactively adjust a camera setting.
For example, in the focus lesson, as you change the focus ring, the diagram on the left illustrates what happens inside the camera while the photograph of a wooden train changes before your eyes. Each lesson also contains a lengthy technical description.
This book will appeal to anyone who wants to learn more about the fundamentals of a digital SLR camera.
