it serves as creative tool. For one always has
a choice of correcting, not correcting, or
overcorrecting to achieve the most attractive,
dynamic, or creative effect. And because the
shifting movement is continuously variable, any
in-between setting may be used to accomplish the
perfect effect.

Supplied anly with K 1000
Filters have an important function in photography.
They affect some of the light rays which pass
through to the film so that the color or nature of
this light is changed.
Filters may be classified roughly into three groups:
(1) filters for black-and-white film, (2) filters for
color reversal film, and (3) filters for all color
(reversal and negative) film.
The principal filters for black-and-white film are:
Uv, ¥1, Y2, 02, R2, and YG. Principal filters for
color reversal work are: Skylight, Cloudy, and
Morning and Evening. Available for all color films
are: filters for flash and filters for photoflood.
Applications —
® UV (ultra-violet) filter — absorbs (or holds
back) ultraviolet light rays (invisible to the
human eye) and reduces distant haze in the
picture. This filter is often kept on the lens
constantly for protection.
Y1 (pale yellow) filter — slightly absorbs blue,
emphasizing the contrast between the blue sky
and white clouds.
Y2 (medium yellow) filter — has a stronger
effect than Y1, bringing out the white of the
02 (orange) filter & R2 (red) filter — have
stronger correction of blue than the Y2, giving
the maximum sky/cloud contrast.
The R2 filter is absolutely necessary for
infra-red photography.

® УС (yellow green) filter — slightly darkens the
sky and all red tones. Recommended for
outdoor portraits as this filter darkens flesh
tones slightly. \
Of the above filters, the Y2 and O2 are a must
for landscape photography.
@ Skylight filter — absorbs blue and ultra-violet
light rays. Preferable for landscape photography
when the bright sky is to be toned down while
the foreground requires no correction.
Note: The Skylight filter may be very useful
for color photography. But remember that the
color rendering abilities of a film vary
according to its brand.
# Cloudy — suitable for use on cloudy days to
lighten excess blue.
£ Morning & Evening — suitable for use at sunset
and sunrise to lighten excess red.
® Filter for flash — used to bring light from a
flash into balance with daylight film. It should
not be used with a color flash bulb, sealed in
blue glass.
s Filter for photoflood — used to bring photo-
flood lighting into balance with daylight film.
It should not be used with a color photoflood
or photospot.
Polarizing Filter
Light is “polarized’’ when it is reflected from the
surface of glass, water or any other high-gloss
medium. The light from the sky, particularly at
an angle of 60° — 90° to the position of the sun,
is also polarized. A polarizing filter reduces or
eliminates surface reflections when photographing
subjects behind glass, under the sea, etc,; it also
darkens blue skies without affecting the rest of
the scene. This type of filter can be used very
effectively for color photography. (You can
examine the actual effect of a polarizing filter by
attaching one to a Pentax camera and looking
through the viewfinder as you adjust the filter.)
SMC Filters
SMC filters are multi-layer coated as precisely as
are SMC Pentax lenses themselves. They never
impair the performance of these lenses, nor do
they ever cause a loss of sharpness or contrast.
They are very useful aids for photography.
SMC filters are available in four sizes: 49mm (UV,
¥2 02, R2, Skylight, Cloudy), 52mm (UV, Y2,
02, R2, Skylight, Cloudy), 58mm (UV, Y2, 02)
Sklight), 67mm (UV, Y2, 02, Skylight) and 77mm
(UV, Y2, 02, Skylight).
The main purpose of a lens hood is to shield the
lens from the light outside the picture area, which
might otherwise cause unwanted reflections inside
the lens.
In addition, a lens hood protects the lens against
dust, dirt and fingerprints; it even helps keep out
rain. Therefore, this lens accessory is often used
simply for lens protection,
Using a spring mechanism, Pentax lens hoods fit
directly onto the rim of the lens. They will not
slip off easily, even if the camera is handled roughly.
® Rectangular hoods
There are 5 types of rectangular hoods available, one
each for the following groups of SMC Pentax lenses:

0.47 x to 0,99 x with the 55mm lens.
Regardless of the lens being used, whenever
working at magnifications greater than life-size,
better results can be achieved by reversing
the lens.
One side of Reverse Adaptor K screws into
the 49mm or 52mm front threads of the lens,
and the opposite side bayonets into the K
Mount of the camera body.
