FURTHER USEFUL HINTS
To use deformed and non-standard cassettes is asking for trouble. With all cassettes,
particularly refilled ones, make sure that they are not bent or damaged, and that
the film sl ides out
easily.
If the film is too short, the rap id winding lever may lock half-way during its movement
when advancing the film for the last
exposure.
The same may happen if you try to
utilize the full length of the film to get more than 36 exposures on
it.
In such a case
never try to force the lever forward or back.
Instead,
rewind a short length of the film
a
s
described on page
25,
fully pull out the winding lever, and then rewind the whole
film in the usual
way.
FOR AGFA CAMERAS -
AGFA FILTERS AND LENS HOODS
Agfa filters help to achieve accurate tone reproduction of the different colours.
We supply parallel ground filters, evenly dyed in .the mass, to satisfy the most
stringent
requirements.
They are available in the following depths:
Light yellow, medium yellow, yellow-green, and
orange-red.
Colour filters naturally require increased
exposures.
These are best expressed by the
filter
factors,
which, however, largely depend on the sensitivity of the film. Most film
manufacturers therefore enclose factors for the most usual filters with their films.
