Mine Buildings

I processed a mixed batch of Infrared film back on March 20th.  This included three different types of film, all in the same developer.  Back in the early 2000's I purchase a couple of boxes of a new, at the time, infrared film.  This was Maco IR820C Aura.  I believe that Maco was affiliated with, or was a brand name of Efke.  Shortly after that the plant used by both companies suffered a fatal equipment breakdown on their sheet film manufacturing line.  All of the sheet film products were immediately discontinued.  I shot some of the film that I had purchased, and then for a decade or more a partial box of 4" x 5" laid around in my freezer.  Last year I decided that I'd better load this stuff and use it up.

So this batch of film had a best before date of April 2007.  I loaded this sheet into a film holder in February of 2025, and got around to exposing it a couple of months later.  I unloaded the exposed film and stored it in my fridge until this past March, when I finally developed it.  

The film was developed in Kodak T-Max Developer, 1:4, for 7:00 minutes at 24C.  I messed up a little as I intended to give 8:30 minutes of development, so the negative was a little thin.

This is a shot of the coal tipple and wash building at the Nordegg Historic site.  I shot this on April 18th 2025, at about 2:00 in the afternoon.  I used my Ebony SV45Ti view camera and a wide Schneider Super Angulon 90mm lens.  A #25 Red filter blocked a good part of the visible spectrum allowing the film to be exposed more by infrared wavelengths.  The exposure was for 1/4 second at F22.0.
