The choice of film is an important part of
photography, and you have a wide variety to
choose from. Films differ in a number of
ways including ASA rating, exposure lati
tude, color rendition and color temperature
among other variables. Some, such as in
frared film\ require the use of certain filters.
Depending on the type of film, a color
temperature conversion filter may be neces
sary under certain lighting conditions. And,
of course, you have the basic choice be
tween
two
types
of
color
film:
color
negative film (for prints) and color reversal
(slide) film. Film can be purchased either in
cartridge
form
with
varying
numbers
of
frames or in bulk form. Either type can be
loaded in the A-1. Although bulk film is a
little more complicated to handle since it
must be cut to the desired number of frames
and handled in complete darkness, there are
simple
devices
for
this
purpose
on
the
market and it is cheaper than cartridge film.
For
more
information
concerning
film,
please refer to a book on photography or ash
your local film dealer, and please pay careful
attention to the film data sheet.
Aside from those instances when a specific
filter is required, filters can also be used to
emphasize certain colors for more clarity or
special effects. Canon offers a wide variety
of filters for both black and white and color
films. It also offers a gelatin filter holder
which can hold up to three filters at a time
and can be attached to various diameter
lenses by means of adapters. Since the A-1
has a through-the-lens meter, there is no
need to make any exposure correction with
filter factors when a filter is attached.
