Adjustment 1
Changing ASA Index
Divide the ASA index of the film by the exposure
factor of the filter. Set the film speed dial to this
figure.
For example, a Y3 (exposure factor 3) filter is used
for an ASA 100 film, the compensated ASA index is
100 -r 2 = 50. Reset the film speed dial to ASA 50.
Adjustment 2
Adjusting T/stop
Adjust the T/stop by turning the aperture control
ring accoring to the exposure factor of the filter. The
T/stops are graduated in a multiple proportion.
Increase the T/stop by 1 graduation when using a
filter with an exposure factor of
2
and by
2
graduations when using a filter of an exposure factor
of 4.
