B + W 67mm Basic 093 Infrared Filter, Black Red 830

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.B+W Infrared filter - the special filter for extreme contrasts. With the B+W Infrared filter, the existing residual sensitization can be exploited for experimental black-and-white photos with high contrasts.Green leaves and grasses are reproduced from bright to white. A "wood effect" with dramatic contrast between clouds and sky can be achieved.Note: Infrared photography is not a substitute for a thermal imaging camera. The pictorial infrared photography described above is often confused with thermal photography. This also forms images from infrared radiation, but in a much higher range (from about 10,000 nm and above)
