This document discusses various photographic terminology including shutter speed, ISO, aperture, depth of field, exposure, color balance, white balance, composition, the rule of thirds, analogous colors, and complementary colors. Shutter speed determines the length of time the sensor is exposed to light, affecting motion blur. ISO measures the camera's light sensitivity, with higher numbers allowing faster shutter speeds in dark situations. Aperture and depth of field relate to the range of what is in focus. Exposure can be manual or automatic depending on camera settings. Composition refers to how the elements in an image are arranged. The rule of thirds provides a guideline for effective composition. Analogous and complementary colors are used to describe relationships between hues.
