Aimed at the more experienced amateur photographer, this concise guide explains the fundamentals of exposure and how varying three parameters--shutter speed, aperture and ISO--can be used creatively and practically to determine correct exposure, but deliver substantially different results. The mechanics of exposure are discussed: the nature of light and how metering affects exposure; light's relationship to color; the importance of white balance; the use of flash; an appreciation of dynamic range; and the ability to read histograms. Illustrated with the author's own stunning images, the book analyzes the effects of exposure on portrait, landscape, night and low-light photography, and when capturing action and sports images. Post processing techniques in the digital darkroom round off this invaluable guide to getting the best results from your photography.
