After having used infrared film in 2012 and earlier, I have been struggling a bit with fogging. I’m pretty sure the problem was due to the fact that it takes a while to load my Pentax 67II; my Pentax 645NII is much easier to load in a darkened room so I went back to this camera even though it meant that I had to remember to switch off the exposure data recording on the side of the negative as this also fogs the Efke IR820 film.
This summer I wanted to try again, I followed the notes that I had taken for this film and used F/11 and 0.5 seconds as exposure on that fine and sunny day.
As I was only experimenting, trying to see if I could successfully expose and develop a roll of Efke IR820 film, I only exposed a handful of negatives. Of course, then the weather changed and the clear skies and burning sun were gone.
I didn’t want to wait too long before developing the film, so in the end I decided to expose the last frames as a normal ISO 100 film without using the Hoya R72 filter. What do you know, the results are a bit grainy for an ISO 100 film, but overall it isn’t a bad film.
