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 lines with respect to the subject brightness (Exposure
Value) gradations on the left and top edges of the graph.
Example:Using an EF50mm 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 (1/320 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.
