Shutter speed

Program Line Description

The lower horizontal axis represents the shutter speed, and the right-hand vertical axis represents the aperture value. The combinations of shutter speed and aperture value automatically determined by Program AE are shown as colored lines with respect to the subject brightness (Exposure Value) gradations on the left and top edges of the graph.

Example: Using an EF50 f/1.4 USM lens with a subject brightness of EV11.5, the point where the diagonal line from EV11.5 (on the top edge) intersects the Program AE line represents the corresponding shutter speed (1/250 second) and aperture value (f/ 3.5) that the program sets automatically.

The diagonal arrowed lines at the upper left indicate the metering range for each ISO speeds.
