This light blue filter cools lighting situations, but not as dramatically as the 80 series. These filters are used for more subtle changes in colour balance . They are often known as light balancing filters rather than conversion filters, as they shift the colour temperature in smaller degrees to balance the colour of the light to the colour sensitivity of the film. The 82 increases colour temperature from 3100K to 3200k. 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.
