Neutral Density Filters
These filters reduce light transmission uniformly over
the visible region of the spectrum, in definitive steps. Although used
mainly in colour photography for reducing light levels without colour
change, they can also be used for black and white photography. They are
particularly useful for compensating for too much light, in circumstances
where changing the shutter speed, aperture or film type is not possible
or desirable. For example, exposure time can be increased to achieve special
effects when photographing running water and waterfalls etc., without
adjusting the aperture. In addition, depth of field can be reduced by
increasing the aperture by the stop value of the filter used. For example,
if the aperture is required to be f4 yet correct exposure is at f8 and
the speed cannot be changed, a 0.6ND will allow the setting of the f4
aperture.

Flourescent Correction
Filters
This system offers filter solutions to many fluorescent
correction problems. Both colour temperature conversion and green absorption
functions are combined into one filter; the filter used will depend on
the fluorescent light and film type.

Colour Compensating
Filters
A range of filters recommended for use either in front
of or behind the lens. They control the spectrum by reducing the transmission
at specific wavelengths. They are primarily used to colour balance films,
the required filter being determined as a result of tests, or as specified
by the manufacturer. They can also be useful for correcting light sources
for which no one conversion filter exists, or for adding a deliberate
colour bias.
The values shown are approximate
exposure increases to compensate for the filters used.

Colour Temperature
|
A set of four filters used to make major
corrections to the colour temperature of light entering the camera.
They create a balance between the colour temperature of the light
source and the CT requirements of the film, so avoiding colour
casts of the finished image.
|
85B, 85C, 80C, 80A
|
|
|
Fine Colour Temperature
|
This set enables minor colour temperature
corrections to be made, and is usually used for fine adjustment
of colour temperature, creating a warm or cool feeling on the
image.
|
81D, 81A, 82A, 82C
|
|
|
Warm Up
|
Four filters used to add warmth to portraits
and landscapes. The degree of warmth increases across the range
of the filters.
|
81, 81B, 81D, 85C
|
|
|
Daylight Flourescent
|
Camera filters for use when shooting under
fluorescent lighting conditions with daylight film, together with
a selection of lighting filters to be placed over the flashlight
(if used) to balance the flashlight. All the light entering the
camera, including that from the flashgun, must be given the same
spectral output as the fluorescent, to allow perfect correction
by the camera filter.
|
FLD3600, FLD4300, FLD5700
|
|
|
Tungsten Flourescent
|
Three camera filters for shooting under fluorescent
lighting with tungsten film, together with a selection of lighting
filters to place over a flash gun. The reasons for use are as
described in the daylight fluorescent section.
|
FLB3600, FLB4300, FLB5700
|
|
|
Neutral Density
|
These three filters adjust exposure without
affecting colour balance and can be used with all standard film
types. Exposure can be increased by 1, 2 or 3 stops to suit individual
requirements.
|
0.3, 0.6, 0.9
|
|
|
Black and White
|
A quartet of filters which all absorb varying
degrees of the blue and blue-green parts of the spectrum, creating
different tones and contrasts of skies and foliage on black and
white film. They can also be used to create special effects.
|
8, 11, 21, 23A
|
|
|
Magenta
|
Five CC Magenta Filters which are used to
absorb the green cast which can be found when photographing under
fluorescent conditions. Using more than one filter at a time achieves
greater absorption. These filters can additionally be used in
conjunction with colour temperature filters to achieve an exact
colour balance on film.
|
CC05M, CC10M, CC20M, CC25M, CC30M
|
|
|
Soft
|
The Soft Set consists of five filters, each
offering a subtly different degree of diffusion for use in portraiture
and landscape photography. The soft effect is virtually independent
of aperture or focal length variations, and the degree of softening
increases progressively through the range.
