RE: Infrared

B/W Infrared negative is a normal b/w negative, but sensitive to I/R. So
heat-emitting or heat-reflecting surfaces appear lighter, heat-absorbing
ones darker.  

Infrared Ektachrome is a strange beast. It has the conventional 3 dye
layers, Y, M, C. If I remember correctly, the spectral sensitivities are all
shifted so that infrared appears as red, red appears green, and greens and
blues both appear blue.
In daylight, skies can go pale pink, vegetation blue, etc. At night,
anybody's guess.
Different enough? Yes it's very - interesting -.
Like a secondary corrector with scrambled connections?
