Filters and Exposure Compensation
When using filters the exposure must be adjusted
according to the exposure factor of the filter to
be used.
Adjustment by Changing the Film Speed Dial
Setting
Divide the ASA index of the loaded film with the
exposure factor of the filter to be used. The figure
obtained is the ASA index of the film when the
filter is used. Therefore, set the film speed dial
to this ASA figure.
For example, when a Y3 (exposure factor 2) filter
is used with an ASA 100 film, the compensation
ASA number would be:
100^2 = 50. In other
words, the film speed dial should be reset at ASA
50,
