In film-based photographic education, strong programs and writings have placed great emphasis on making a negative. But to get to the negative, good exposure is required. The beginning of the photographic process significantly affects the final outcome of an image - a fact that has not changed with digital photography. Capture: Digital Photography Essentials concentrates on photography from a digital-capture workflow point of view. The text addresses both the opportunities and limitations of digital photography, and how to work with those opportunities and around the limitations. Authors Glen Rand, Chris Broughton, and Amanda Quintenz-Fiedler discuss the digital tools that allow photographers to capture, create, and maintain high-quality digital photographs. Readers will learn to maximize the potential of their images through an understanding of the core principles and more advanced aspects of the digital photographic process. Various projects that are based on tested teaching concepts for digital photography can be found throughout the text, as well as numerous images that are both inspirational and instructional. Topics include:Digital Cameras Sensors and Lenses Basic Exposure Digital Exposure Digital Capture Workflow Image Files Parametric Editing Digital Zone System HDRI Hybrid Imaging Capture Technology
