Cokin A007 Infrared 89B Filter

Product Description

The Cokin Infrared filter is for both Film & Digital cameras. With a film cameras the Cokin Infared filter must be used with Infrared Colour or Infared Black & White film. The Cokin Infared filter is equivalent to the Kodak 89B wratten filter with a spectrum transmission of 50% at 720 nm. The distinctive feature of Infrared filters is that they "filter" most of the visible rays & let infrared rays go so as to produce spectacular photographic effects. The process in Digital is really easy: once the picture is shot, you must "un-saturate" your image on your computer, in other words transfer it to grey levels.
