Hitech 85mm Black & White Filter – Yellow/Green 11
The Hitech professional quality Black & White Filters are used to reduce or eliminate atmospheric haze, make the tonal reproduction in monochrome imagery more natural and give deliberate emphasis to certain tones and objects.
Filters for use with black and white film have strong colours that block wavelengths sufficiently enough to produce shifts in grey tones.
The Hitech 85 Black & White Filter – Yellow/Green 11 retains tonal value but reduces haze and brightens green.
The Hitech filter system is manufactured by Formatt Filters to offer versatility and creative capabilities to stills photographers. Hitech filters are manufactured using the Queens Award winning CR39 dyed substrate. Formatt developed a method of colouring CR39 in its liquid state, thereby ensuring consistency and accuracy of colour.

By greatly extending exposure times the Big Stopper blurs anything that is moving in your image, for example clouds, waterfalls, rivers, and the sea.
The filter can also be used on cityscapes to blur people or on roads and motorways to blur traffic.
Blenders feature an effect transition that occurs over the entire length of the filter, starting at the top and graduating all the way to the bottom. This allows for a graduated effect across your image without any specific horizon line.
