B+W Infrared Filter 830 77 mm Basic. The B+W 093 infrared filter blocks the entire light spectrum. It therefore appears almost black and captures the pure IR range without visible red. It enables image results with extreme contrasts. The visible lights will be blocked almost completely up to 800 mm. The filter is dark red, almost black. With analog IR film or IR sensitive digital cameras it delivers a fantastic wood effect (white leaves) and a typical dark sky. The exposure values vary according to the digital camera model being used and are best determined by experimenting. They are usually in range of a few seconds. Focusing is performed first without a filter using IR focus correction.
