Veteran photographer Bryan Peterson demystifies complex concepts of exposure in photography by explaining the fundamentals of light, aperture, shutter speed, and how they interact with and influence one another. This book explains how to get or lose sharpness and contrast in images, freeze in action, and take the best meter readings while also exploring filters, flash, and light. This forth edition includes all new images as well as an expanded section on flash, tips for using colored gels, and advice on shooting star trails.
