Polyester Filter Sets
Colour Temperature Set
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.
Fine Colour Temperature Set
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.
Warm Up Set
Four filters used to add warmth to portraits and landscapes. The degree of warmth increases across the range of the filters.
Daylight Fluorescent Set
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.
Tungsten Fluorescent Set
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.
Neutral Density Set
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.
Black & White Set
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.
Magenta Set
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.
Soft Set
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.
