ETTR, Exposure to the Right, results in an exposure that maximizes captured signal-to-noise and provides the best information from which to base a final image. This can be achieved in several ways. ETTR images of scenes with low-DR and high-DR require very different processing steps.

Color Management can be confusing. Here I hope to explain how the colors you photograph can be made to survive reasonably intact as they move through the five major color spaces usually encountered from shot to print or post: camera, camera jpeg processor, image processor, monitor, and print or web.

Exposure is determined by the luminance from the scene, the f-ratio, and the shutter speed — only. All other procedures, either in-camera or with the computer, to affect the brightness of an image, including ISO, comprise brightening -- a concept essentially different from exposure.
