There is a saying: There is also the question of how far we are shaped by our genes, and how far by our upbringing. Similar observations apply to infrared IR films. No two emulsions are quite the same genetic uniquenessand even with the same emulsion, each photographer has a different regime for exposure, filtration, development, and printing upbringing. Pictorially, each film is unique, and different again from digital IR. This is why Efke’s exists. The traditional heavy users of IR film–police, military, scientific–have mostly switched to digital imaging.

But a niche manufacturer like Efke can coat enough film to meet the demands of pictorial IR photographers, without having to worry about finding enough heavy users to fund huge coating i820. But what is its “signature,” and how is this affected by the variables mentioned earlier? Well, I would call it a “gentle” film, at least for the kind of subjects I shot and the developer I used.

Grain ir802 reasonably clear-cut, and modest in size; sharpness, in common with most IR films, is fairly low. It is, however, very easy to underexpose. The amount of IR in sunlight is greatest a edke of hours either side of noon, and varies greatly with the angle of the sun: Exposure meters are of limited use, though some are much better than others.

I had most success with a combination of “sunny efk and experience: With the slightest cloud, or in the morning or late afternoon, another stop or even two was advisable. When bracketing, err always on the side of overexposure: In other words, this is not a fast film.

Because the film is so slow, I tried only a few skin tone shots; for me, IR works best for landscapes and especially for old buildings. You may feel differently. Unforgiving though it may be for exposure, development is another matter. This was far too short, though I did get one rather nice landscape by printing on Grade 5.

With subsequent rolls I kept increasing the developing time without any particular ill effects until fog became detectable at 16 minutes: At 14 minutes, I never needed less than Grade 2 or more than Grade 4, at least with a half-competently exposed negative.

This is a “true IR” film, sensitized to wavelengths completely invisible to the human eye. As the name suggests, it is sensitized a little beyond nm; for comparison, Kodak’s High-Speed Infrared is sensitized almost efkke nm.

Such films need to be loaded into the camera in complete darkness: I820 in the dark can be a royal pain in the anatomy. I found it easiest to load two bodies in the darkroom at home, rather than using a changing bag in the field. Even then, three of the nine rolls I loaded in the dark had fogged leaders and some light strike through the cassette lips: Because the light strike was only on some films, I suspect that it happened in my custody.

It may be that lr820 black plastic film canisters are not fully opaque to IR, and should not be exposed to sunlight. In the future, I would wrap each canister in aluminum foil if I were taking it outside the house.

Remember that you also have to unload the camera in complete darkness, never exposing the wound-off cassette to light either. Both the “white foliage” effects effke the haze-cutting ability of IR are clear here, but because it is a late-afternoon shot, contrast is low: Hicks, All Rights Reserved. Focus using the rangefinder, then transfer the focused distance to the IR focusing mark.

If you are using a reflex, you will need to focus with the filter off, or scale focus. Log in or register to post comments. Latest Trending Photos Videos. Our 10 Favorite Film Stocks of Check Out This Video on Ready for Your Close-Up?: Yi M1 Mirrorless Camera Review.
