Program Line Description
The bottom horizontal axis represents the shutter speed and the right
vertical axis represents the aperture value. On the left edge and top
edge of the graph, the Exposure Value (EV) is indicated for the
respective shutter speed and aperture value combination set by the
Program AE mode and denoted by the program line.
Example: When the 105mm focal length is used and 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 (1/125 sec.) and aperture value (f/5.6)
which the program sets automatically.
The arrowhead lines above the graph indicate the metering range for the
respective film speed.
