PASTEL FILTERS
When one wishes to bring
a romantic or mysterious atmosphere to an image, to put
an often disappointing reality in its best light, or to give the image a visibly painterly
appearance, every image creator must need, at one time or another, a diffusion filter
whose effect is either barely perceivable, or that lends a somewhat dreamlike form to
the image.

whose effect is either barely perceivable, or that lends a somewhat dreamlike form to

In this area, the choices COKIN offers are as vast as its worldwide reputation. The Z-PRO line
offers 20 filters of this kind, presented in the 6 following pages.

DIFFUSER FILTERS
The
outstanding images taken with a COKIN diffuser filter are now too numerous to mention !
These filters use
an exclusive COKIN process created by its founder and kept carefully secret ever since in the company
laboratories. It’s the way they diffuse the light from the luminous points of the image that gives shots that
characteristic aspect. Copied numerous times but never equaled, the Z-PRO diffuser filters exist in 4 intensities,
from the most subtle to the most marked. There is nothing else like them on the market.

The Diffuser Light (820) is best for landscape photography and intimate portraiture. There is no equal for reducing
facial wrinkles and small imperfections of the skin and is almost unperceivable.
•
With the Diffuser 1 (830) and especially the Diffuser 2 (840), you can literally make the years melt away as if by magic,
leaving behind only radiance and glow. As for nature shots, they will have a completely different dimension! Discovering
these filters means entering into a world of images that were the mark of an era, and when one flips through a current fashion
magazine, it’s clear that they’re back in style!

The Diffuser 3 (850) offers such a great diffusing potential that it virtually transforms itself into a shower
curtain and you are propelled into Brian de Palma’s “Dressed to Kill”. The nude remains its subject of choice.

According to whim or necessity,
in numerous photographic domains (portrait, fashion, nature or landscape, to
name but a few), photographers and filmmakers time and again choose the COKIN soft diffusion because of their
variety paired with such remarkable quality.
Diffuser and Pastel filters
are among the most difficult to manufacture. Indeed, toning down an image is not the
same as making it out of focus... It is all a matter of balance and mastery of the diffusion of light, as engineers of
specialized optics well know. These types of filters transmit, depending on their degree of diffusion, 70 to 90%
of the image’s original sharpness, and use other processes to obtain the effect of diffusion for the rest of the
spectrum, playing either on the sharpness or the contrast, or both.
With
these filters you enter right into a romantic atmos-
phere,

so strong is their effect on the image.
They add a soft, unique touch to portraits; hair flows
like silk, skin is warm and expressions languid. As
for still lifes, they come close to the appearance of a
painting, attaining an incomparable atmosphere that is
delicate and fresh.

These two filters – the second being simply stronger
than the first – bring out lively colours and intense lights,
diffusing and treating them like an artist.

These filters give superb outdoor results, in cloudy weather, and
indoors when light is coming sideways from a window. The expo-
sure is sometimes a delicate issue. Double, even triple your expo-
sures by overexposing at intervals of 1⁄2 or 1 stops. Finally, these
filters combine wonderfully with coloured orange or blue filters to
create a specific look, or even with graduated colour filters.

Used
on an everyday basis in cinema
for some time now, the net filters diffuse and disperse reflected
light. The Z-PRO line offers four net filters. Depending on their tonality, they conserve and
contrast (blacks), or diminish (whites), reducing the power and the saturation of tints. According to the
fineness of their mesh, their effect can be marked or discreet: the tighter the mesh is, the more pro-
nounced the diffusion.

In portraiture, these filters reduce or eliminate undesired reflections on the skin, such as on the nose,
the chin or the forehead, whether they be due to the sun, to flashes, or to spotlights. In landscapes,
they ensure a harmonious distribution of light when using backlighting, bringing their unique touch to
the image.

As a general rule, one can say that their effects are strong for small details
while uniform surfaces are only slightly affected. Always place them in the
first groove and do not go past an aperture of 4 or 5.6 while working, especially
if you’re using a wide-angle lens, otherwise you risk having their structure
appear on the image.

They are in essence wide-aperture filters which means that they may raise a few
difficulties for use with landscapes where a wide depth of field is required.

IN PRACTICE,
the results obtained
with diffuser filters
are closely linked to
the intensity and the
quality of light used.
Think of overexposing
by 1/3 or 1⁄2 of a stop
to accentuate their
effect. You will then
see that bright lights
take on a completely
different dimension!
In addition, the effect
