Lee No 15 Deep Yellow 100x100 Filter for Black and White
Using tungsten film in daylight will produce a bluish cast in the photograph. The 85 series will produce natural colours when shooting with tungsten film outdoors. A #85 filter will decrease the colour temperature from 5500K to 3400K and produce slightly cooler results than an 85B. This filter combines an 85B conversion filter with a Neutral Density .6 (two stops) filter.
The Hitech 85mm Standard Neutral Density 0.9 Filter is a professional quality 3 stop (8x) ND filter. Hitech Neutral Density Filters extend the control of exposure parameters and are used in both colour and black & white photography to reduce the intensity of visible light. They are extremely useful in pictorial photography when shooting maximum apertures in bright light. Since ND filters uniformly reduce light of all wavelengths, there is no effect on the colour rendition. These 84x84mm filters fit in the Cokin P filter holder and are manufactured from the highest quality optical grade polyester resin.
