photosWhelp, in another 'they all can't be gems" moment, looks like many of my sheets of Rollei IR 400 are underexposed. Turns out IR400 really isn't natively 400 ISO. Word on the street is that it's Aviphot 200 but even 200 ISO might be overly confident (which is what I rated it at when not using an IR filter while on our trip as I recall).
For this shot, I metered on the grass through the window, so I expected the inside might be fairly dark by comparison. Still, this is much darker than it should be.
I threw in a test sheet with the exposed sheets yesterday and those results show it might be as slow as 50 ISO when used as a normal (not-IR) film in Adox XT-3 (which gives a speed up with T-Max 100 I find and probably does here too). I would have certainly used the Rollei IR sheets differently in Iceland if I had known it was going to be that slow. But oh well! I've got a few more sheets to develop so I might still have some usable images from the film. And overall I have a myriad of photographs I'm very very proud of from the trip. Just part of the journey that is film!
The drainage-ditch creek photo I was excited about did turn out not so bad. It's probably not darkroom-printable but it still looks pretty neat (I'll share that at some point later on).
All that said I generally get pretty good results using Rollei IR 400 for Infrared photography so it's still a film I like. Though I'll perhaps think twice about trying to use it as a normal film without doing more film and exposure tests...
...
...and it would still be great if, oh I dunno, Ilford would give us SFX 200 in sheets...
EDIT: Forgot to include the film curve! I exposed the step wedge at 12 LUX, double what I use for T-Max and that gave me about the same starting point for the toe, which is why I indicated it might be closer to 50 ISO
