If you're looking for a way to put some "sparkle" into the pictures
you've been taking lately...something that will pack a real
punch...a good FILTEr or two could do just that!
What's more...these circles of colored glass can work this magic
with no more effort on your part than it takes to slip one off the
lens, and the other one on!
Simple to use...with either black-and-white or color film...
FILTERS help your film "see" the scene you are shooting just
as your eye does.
What does that really mean...and what can filters do
for your pictures?
A MEDIUM YELLOW filter, for example, will drama-
tize those "fleecy" clouds and give a more natural look
to at least 75% of all black-and-white scenic pictures.
A LIGHT GREEN filter used with black-and-white film
will bring out the details in trees and shrubbery, and out-
door portraits taken with this one will have a truly
"lifelike" look to them.
A POLARIZING filter, to mention another one (used
with either black-and-white or color) will capture dramatic
blue skies, and cut down on reflections bouncing off water,
glass, or shiny surfaces. This filter alone can put your
black-and-white and color pictures in a class by themselves.
The charts on the following pages will help you discover, in a
minute's time, how truly simple it is to improve YOUR pictures
with the aid of a few simple filters! Select one or two to begin with
and add others as you become better acquainted with them.

Filters for use with black-and-white film require an increase in
exposure. Since each "f/stop" on your camera lens gives approximately
twice the exposure of the one before it, changing this stop as
suggested in the chart is a convenient way to increase exposure
when necessary.

Film manufacturers recommend DAYLIGHT type film for outdoors.
If you prefer to use FLASH type film outdoors, use the CON-
VERSION filter (85C type) recommended by the film manufacturers.
The slight additional exposures required when using some filters
with color film (one-third or two-thirds of an F/stop)...are
simple to make.
Just move the lens setting one-third or two-thirds of the way
between the lens opening you would use without a filter
and the next largest lens opening. (You increase exposure by
moving from large "f" numbers to smaller ones...i.e.: f/8 to f/5.6)

Film manufacturers recommend using FLASH type film for pictures
indoors. If you prefer to use Daylight type, use blue flashbulbs such
as Press 25B and no filter. Sylvania M2 flashbulbs (with proper
reflector) need no filter, and Sylvania SF gas-filled flashbulbs
require an 82B type filter with Flash type color films.
When not using your filters, protect them from scratches and
chipping...keep them clean and free from dust, grease, and
fingerprints. (A camels hair brush first, and then some lens tissue
will work fine.)

To make certain you are able to use accessory filters and close-up
lenses with your camera, several manufacturers have provided
special "adapter rings" in a wide variety of sizes and types to
fit all camera lenses.
Generally, the adapter ring slips over the lens mount, or screws
into special threads provided just inside the lens mount; they are
usually described in terms of "millimeters," which simply in-
dicates the exact diameter of the lens mount.
The filters are most often described by the word "Series" (i.e.
Series IV, V, etc.)
If you own an Argus or similar type camera with the same size
lens mount, you will find the chart below of considerable help
in selecting the proper adapter ring and filter attachments.

EXTRA FILTER NOTES
In black-and-white prints, FILTERS LIGHTEN SUBJECTS
that are the same color as the filter. For instance, a red filter will
cause a red object to look very light in the black-and-white print.
There are four general types of FILTERS to use with COLOR
FILMS.
(1) POLARIZING filters are used to reduce reflections and
glare from objects, and to darken skies.
(2) ULTRAVIOLET or HAZE filters, such as a Skylight or
UV-16, help to reduce the blueish haze found in distant
scenes, and in pictures taken in the shade.
(3) LIGHT-BALANCING filters, such as a CC-30M, make
small and minute changes in the color balance of the trans-
parency, and are most often used in exacting color work.
When using a FILTER with a SUPPLEMENTARY LENS,
install the supplementary lens next to the camera lens, and the
filter closest to the subject.
If you use a LIGHT METER and a FILTER, there is a simple
method of compensating for the filter factor. Simply divide the
film speed of the film by the filter factor (the factor is listed in the
film instruction sheet and the filter instruction sheet). Set this
result on the light meter, and use the meter as you usually would.
For instance, say you were using Plus X film and a K-2 filter.
Normal film speed is 80, and the filter factor is 2. Divide 80 by 2,
the result is 40. Set this on the film speed dial on the light meter.
Use the meter normally, as the filter factor computation has been
allowed for.
