sun. When large areas are to
be adequately lighted by flash
it should be fairly obvious that
more than one lamp will be
required. Just how many flash
lamps the individual will need
will depend upon the type Of
pictures he will make. The
average amateur can get along
nicely with two or three ex-
tension flashes in addition to
the one used for the main
light source.
Q. How are filters useful to
the photographer?
A. In a number of ways.
Certain filters are used to
increase contrast. Contrast
between clouds and sky can
be increased enough so that
the clouds will record clearly
on the negative by using a
yellow, orange, or red filter.
Other filters are used to
change tones. AS an example,
in copying, yellow filter can
be used to photograph a print
which has yellow stain. The
copy negative, if the correct
filter is used, will not show
the stain that marred the ap-
pearance of the original print.
Another type of Alter will
allow the camera to "see"
through aerial haze. Such a
filter may be very helpful
when you wish to photograph
a scene where certain areas
are usually obscured by haze.
Dark yellow and red filters are
used for this purpose. If, for
pictorial reasons. you wish to
emphasize aerial haze, a blue
filter fitted over the lens will
do the trick.
Unwanted reflections which
otherwise will prevent your
taking a picture can be elm.
mated entirely by using a
poIaroid filter. The polaroid
filter can be safely used for
this purpose without affecting
colors in the scene, for it is
neutral in this respect. Filters
are used to obtain accurate
black and white renditions of
colorS in a tonal relationship.
We see color as it is, but mono
chrome film sees color in terms
of varying shades of black and
white. The filter is often used
to translate the colors into ra-
tional black and white tones.
@. How are photograms
made?
A. These are light-pictures
made without the use of the
camera. Translucent and
Opaque objects are arranged
harmoniously on a sheet of
Photographic paper which is
then exposed to light. Opaque
objects stop the light entirely
and leave a silhouette, while
the translucent objects trans
NIT enough light to show de-
tails of their structure. Leaves,
flowers, lace-in fact. just about
anything can be used to create
these interesting pattern pic
lures.
A new portable Lumax flash
unit weighs 24 pounds, oper-
ates on four flash cells, has
a flash duration of $1,000
second and a cycling capacitor
time Of IL seconds. A neon
indicator shows when it is
ready to flash.
