The 81 Series of filters control the bluish colouration that affects daylight film. They can also remove excessive blue from the effects of electronic flash. Good for general scenics when the photographer wishes to remove the bluish cast from open shade or just add warmth to the photograph, with an 81EF having the greatest effect. Lee resin filters are 4 x 4" (100 x 100mm) x 2mm thick.

A #85 filter will decrease the colour temperature from 5500K to 3400K and produce slightly cooler results than an 85B. Lee polyester filters measure 4 x 4" (100 x 100mm). Filter factor 1.8 (+2/3 stop).
Lee Blue 05 Resin Colour Correction Filter.
These ND filters reduce light transmission uniformly over the visible region of the spectrum, in definitive steps. They are used mainly in colour photography for reducing light levels without colour change, and 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.
