TPF Noob!
O.K. So as everyone now knows Kodak have (Last year) ceased production of their MUCH LOVED HIE mono IR Film. So now I have to start again finding something to replace it.....
WHAT A MINE FIELD.
I was recommended Rollei 720/400. This duly arrived and I shot a roll of my ever dwindling HIE and a roll of the new stuff (Rollei).
The HIE developed exactly as I expected. (Sunny day R72/89B filter, exposure successful between 1/15th and 1/250 second best at about 1/60th f11 . Deved in Ilford Ilfosol 3 at 70degrees for 7 1/2 mins. FINE...
The Rollei was subjected to a wider latitude as I don't know the product.
from 1/250th to 2 minutes. Nothing seen at all on film until 30 Seconds exposure very little even at 2 minutes !. It is meant to be sensitive at 720 Nm declining through to 820. This SHOULD have provided enough "Light" to work from about 1/30th second. But the first shot I took (Unfiltered, in "Auto" mode at ASA 400) was perfect, so the film stock was good. The register marks on the film were perfect, so the developement was good. as was the camera (a Nikkon F3) and the meter (In the F3).
I am therefore of the opinion that SOMETHING was wrong (Don't know what as the filter is the one recommended in all the literature), and that at best the Rollei 720/400 is only an Ilford SFX wanna be.
I have just bought 2 rolls of Efke IR 820 (Which is supposed to peak at 820 and then die off (closer to but not the same as HIE). and will let everyone know how I get on.
Questions then.
1). What filter SHOULD I use with the Rollei (I still have 9 Rolls of the stuff to wade through) in order to get the best results that this film is capable of delivering.
2). Is anyone out there still using film to shoot IR and has found a replacement for Kodak HIE mono IR film. If so the name of the film and filter combo and any other info would be useful.
3). Is there any chance that in the near future we will be treated to a REAL Mono IR film by a smaller manufacturer who can now see a gap in the market.
