Program Line
The program line below applies when the camera is used in the Program AE < > mode with
an EF 50mm f/1.4 USM lens.
Program Line Description
The bottom horizontal axis represents the shutter speed and the right vertical axis represents
the aperture. On the left edge and top edge of the graph, the Exposure Value (EV) is indicated
for respective shutter speed and aperture combination set by the Program AE mode and
denoted by the colored program line.
Example: When the subject brightness is EV 12, the point where the diagonal line from EV 12
(on the top edge of the graph) intersects the program line indicates the corresponding shutter
speed (1/320 sec.) and aperture (f/3.5) which the program sets automatically.
