Example

You want to use a yellow-green filter (F III) for a shot on

black-and-white film. On the film speed scale you have

set, for instance, 50 ASA (graduation before 64). The

opposite table indicates that the film speed setting must be

reduced by 3 divisions if a yellow-green filter is used.

Your new setting on the ASA scale therefore becomes 25

ASA (see illustration).

When the filter is removed again, remember also to reset

the film speed accordingly - in our example - back to 50

ASA.
