to film orientation, but it is also means that a calibration with three or four exposures can
be done with less than one sheet of film. Although this example doesn't conform to the
rule, it works best to have the doses in approximate geometric progression rather than
in arithmetic progression.
Use the Frame Selector tool to draw
areas of interest in the center of
each strip. A frame can be easily
duplicated by holding down the
"Control" key and pointing/clicking
with the mouse. Calibration defines
the average response of the film so
the measurement areas should be
about 20-25 cm

. Activate the
Calibration Tool by clicking on the last line of the Film Calibration Object and click the
icon in the lower right corner of the Calibration
Window to populate the calibration table with
response values. Then click in the dose column
and enter the doses. Dose values can be entered
in random order as the doses/responses are
sorted/matched in reverse order, i.e. the smallest
dose is matched to the largest response value. By
default the red channel is used for the
synchronization. Click the color synchronization
icon to synchronize responses of other color
channels or to sort matching order or turn off the
synchronization. As soon as all dose values are
entered the data points and fitting functions are
charted in the Calibration Window.
