Fuji X100: Into darkness with the B+W 093 filter |
The Machine Planet

We have been in dark places with an infrared-converted X100. Sometimes these dark places have been in bright sunlight; it’s just that what the camera sees is another world, defined by light humans can’t see. The Marche du Nain Rouge, a parade through some of the world’s most non-gentrified areas, is an excellent place to demonstrate the capabilities of this fully operational battle station device. The B+W 093 passes an insignificant amount of visible light and creates monochrome infrared; at this wavelength, light pretty much slices through the RGB filter array (and we have been able to test this using a beta of Accuraw Monochrome). With a converted camera, sensitivity is a couple of stops less than with visible light (and about 8 stops higher than trying to use an IR filter on an unconverted camera). We have noted this before but are noting it again: the 1/4 wave multicoating used on modern cameras is completely ineffective against flare and ghosting from infrared frequencies. This makes lens hoods important and imparts a little bit of glow to everything. It is not the hazy, slightly out-of-focus effect you get with DSLRs that can’t focus IR and older IR film. It is more the look of an old Tessar on Plus-X. That said, with no color information, there is no color-specific tonal correction or false color work……
