HOYA 67MM RM72 INFRARED FILTER , Optically opaque to the human eye, this filter is primarily used for photography with infrared films. R72 passes only infrared rays above 720nm. Special effects can be obtained using digital cameras,  however SLR models are not easily used because there is no way to focus or see the subject, in this case non-SLR rangefinder digital cameras are ideas as one can use the built in LCD screen to compose, manual focus is a feature that also is desireable since some cameras will have a hard time focusing accurately.

RM90 passes only that above 900nm. Often used in crime detection, medical photography, detection of distribution of vegetation, etc.
