Rollei Infrared 400 film
I am on my last roll of Kodak i/r so have been playing about with Rollei I/R 400 and I'm impressed. Deinitely not Kodak but a good infrared film in my opinion and one well worth trying. I resisted the temptation to go for the Efke I/R films as they looked to be very slow, but I will give them a go later.
The Rollei film has a stated ISO of 400 but I reckon it is more like ISO 200 in my hands. An R72 opaque type filter is essential and so is a tripod. I decided to use Rodinal at 1+25 for 7.5 mins just because it was listed on the Big Dev chart.
So using the camera's meter with the filter on 200 IS0 produced the best looking neg. Or metering with my Sekonic at 30 to 50 ISO produced the best neg (NB not metering through the filter). This seems to indicate a loss of approx 5 stops through the R72.
The attched snap is a straight neg scan of my back garden taken mid PM with clouds and sun. I am going to print the neg tomorrow and will post a copy of that later.
To sum up: a useful i/r film with a handy ISO of 200 (400 on the box) that develops well in Rodinal. Can be loaded in the shade with no problems and to my eye is very akin to the old Konica i/r film but much faster.
