5.9 Photography TLDR🔗⧉

Choose time for motion, aperture and focus for the required depth, then use ISO to obtain a useful encoding. Gain adds no photons. Learn whether the camera's histogram and clipping warnings describe raw data or a processed preview.

Choose viewpoint before focal length. Stabilization helps camera shake; it does not freeze a moving subject. Add or redirect light when exposure alone cannot produce the relationships you need. An ND filter permits long exposures or wide apertures before saturation.

Use several frames when their additional measurements help and their motion can be handled. Keep the source, inspect fusion boundaries, and treat a good single frame as a valid choice. Develop for the photograph's purpose, then resize, color-manage and sharpen for its destination. Judge the result at that size. For evidence or measurement, retain the processing history and distinguish measured content from invented content.
