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 EV12, the point where
the diagonal line from EV12 (on the top edge) intersects the Program AE line
represents the corresponding shutter speed (1/350 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 the
indicated ISO speed.
