Hitech filters for Black & White Photography produce a range of effects including control of contrast, tonal correction and enhanced skin tones. Originally designed for use with black and white film, they are also a great tool for general colour imaging. The Yellow 8 black & white contrast filter increases contrast and is particularly useful for midday sun and deep shadow. It accentuates clouds, reduces haze and will reproduce distance better. This 67mm filter is usable with Hitech 67mm holder systems or any 67mm (2.67″) holder. The filter is also available in 85mm, 100mm, 150mm and 165mm sizes. Hitech filters are made from the highest quality 1.5mm optical resin.
