In photography, which is essentially recording patterns of light, shade, and colour (while painting is the individual’s interpretation of these patterns, hence its unparalleled subtlety), "highlights" and "shadows" are the brightest and darkest parts of a scene or image. The challenge for a photographer is to adjust photographic exposure (unless you want special effects) so that the film or sensor, which has limited dynamic range, records detail without clipping the shadows and highlights.
