Around 30 years ago in the early 1980’s I shot a roll of Kodak Infrared Ektachrome E4 Slide film (you can see an image from that roll here). It was magic, but I never got around to shooting more of it.
A couple of weeks ago I shot two more rolls of Colour Infrared Slide film, purchased from the Film Photography Project online store. They have a limited supply of an equivalent E6 process infrared slide film, expired but cold stored. Here is one of my favourite images:

With the proper filtration (in this case a yellow-green filter and a polarizing filter) you get some really interesting colour effects, with foliage coming out red in a lot of cases, and blues tone becoming very vivid. The world becomes a different, alien, fantastic place.
I wish I could shoot this film stock all the time, as I don’t feel digital infrared (either post-processed faux infrared, or specially converted digital camera) gives the same magical effect. But I must be realistic: this film is not cheap, it is no longer made, and E6 slide processing is getting rarer, except by mail order.
A magic, but transient moment, and I mourn its imminent passing.
