Infrarot Glasfilter RG 645
Red
A very interesting area in photography is infrared images for creative and artistic effects. Heliopan filters made from Schott glass, pass only the exact areas of the IR Spectrum: RG695(89B), RG715(88A), RG780(87), RG850, RG1000. For landscape pictures we recommend the R715 to RG830 filters.
