shutter speed
How long the sensor is exposed to light for a single frame.
Shutter speed sets both exposure and the rendering of motion. Roughly, a jet needs 1/500 or faster to be sharp at close range, a propeller aircraft wants 1/125 or slower for a full disc, and a night ramp shot on a tripod may run for seconds. It is the first thing to set in aviation photography and the reason shutter priority exists.
