Notes
Experimenting with Ilford SFX 200 film which is a lot more infra-red sensitive than normal black and white film, although, I am sure, it is not a real infra-red film like the Rollei and Efke films. I'm not too happy with the results as the photos came out rather grainy.
I used the special Ilford SFX200 filter and added 4 stops as prescribed. In hindsight, most shots were overexposed and next time I will only add 3 stops. Luckily I had bracketed most shots plus/minus 1 stop and I ended up using the -1 stop shots. The filter is opaque which makes focussing and exposure rather difficult: I had selected manual focus and set the speed of the film to ISO 12 by hand. I would remove the filter, get the focus and exposure, lock it, put the filter back on and release the shutter.
Ilford SFX 200 @ EI 200, developer HC-110 9 mins, Ilford SFX200 filter, +4 stops
