Hoya 77mm Infrared Infrared R72 Filter
Hoya 77mm Infrared R72 Filter is used for photography with
infrared films. Infrared film is also sensitive to ultraviolet rays and the
shorter wavelengths of the visible spectrum, so
Hoya 77mm Infrared R72 Filter is necessary to filter out all
but the infrared rays.
Hoya 77mm
Infrared R72 Filter passes only infrared rays above 720nm; RM90
passes only that above 900nm. Hoya
77mm Infrared R72 Filter is often used in crime detection, medical
photography, detection of distribution of vegetation, etc.
In ordinary photography with infrared film or infrared colour film, the Y(K2),
O(G), R(25A) and other filters like Hoya
77mm Infrared R72 Filter can also be used to change the
contrast or colour effect.
