Tiffen 67mm Deep Blue 47B Color Balancing Filter

Description

A 67mm 47B Deep Blue Colour Balancing Filter from Tiffen is a deep blue filter that accentuates haze and fog. It is also used in dye transfer printing, for contrast effects and colour separation and tricolour work (lightens blue tones). Tiffen's ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision aluminium rings.

Key Features:

Tiffen's ColorCore glass is sealed between two optical glass sheets. In this way, Tiffen can better control the various densities of their filters and thereby create more exact degrees of filtration. This process makes for greater accuracy of colour as opposed to glass that is simply dyed and become subject to deviation during the dyeing process.
