Reading Time: 3 minutes Kodak Ektachrome Professional Infrared EIR Film has become a bit of a holy grail for experimental photographers, and I have seen it command prices of over £100 on ebay. I was lucky enough to get hold of a roll in a mixed bundle of old films (along with 2 HIE Black and White infra-red rolls for about £14 – I guess the guy didn’t know what he had!).

EIR is a ‘false colour’ technical film, coated on an Estar base with a sensitivity from 380-900nm – this covers the full visible spectrum and some of the near-UV and all of the near-IR range. Near Infra-red wavelengths are rendered as a deep visible red, and due to the ‘Woods Effect’ (reflection of n-IR wavelengths from foliage) this means that foliage comes out in this colour creating strange and bizarre visual effects.
