That was not aimed at you. It was aimed at others who do not have any experience with film.
Why do you assume my age?
What’s more I think the split is at least fifty percent “young” whatever that is, that shoot and are enthusiastic about film.
I’ve met far more stodgy older men, why are dead set on digital. And who are very critical and not understanding about the why and how to use film.
Sirius: FWIW, when I came back to film - my life's experience... by which I mean to say when I dropped a 5 year dalliance with digital and restricted it mostly to camera scanning, I think I was surprised at how hard initially it seemed to be to find things like B&W contrast filters. Filter companies generally don't advertise film filters any more.BW contrast filters are what we all grew up with. Duh. But I never shot IR film. So the same holds true in trying to find IR filters for film. So my question is whether folks know if some of the IR filters made for digital (which I don't have because IR digital involved a lot of expense in "fixing" your sensor to do it right) will work with film... because the digital IR filters are what's advertised. Any idea?
Don't buy a Hoya IR72, they're expensive cos you're paying for the name. I bought mine from SRB Photographic; they're a fraction of the cost of Hoya's and work perfectlyAnon Ymous: THanks! Of course I thought Agfa ding dang died. It lives?
The question of "will a filter for IR digital" work for IR film remains open. I tend to use Lee's 100X100 filters, but these can get expensive. So figuring this out is kind of important. Hoya R72 might be a better bet, huh? Yes, this means I'm thinking of ordering some IR film.
I'm drinking a stout on that"We few, we happy few, we band of brothers" and the added benefit is that it works on all other days as well as St Crispin's day
I like your style. Stout was a popular drink here in the U.K. before the world turned lax and sour we oldies sayI'm drinking a stout on that
Oh some weird people in the far north of Scotland still seem to abuse itYou hardly ever hear of anyone who drinks it now.
Why 400S when it’s been repeated many times over that it’s really just 200S?Just wanted to say thanks to all for the great info and beautiful images in this thread... it has inspired me to order some Rollei Retro 400S and an 89B filter so I hope to join the party soon.
Why 400S when it’s been repeated many times over that it’s really just 200S?
I mean why encourage that kind of flimflam?
Not that it will mean much difference to you personally. I’m just interested whether you knew, and if I have misunderstood something?
Also what filter did you order and where?
Yes, one small purchase is not going to make a difference, but a thread like this can cascade and influence for decades.Yes, I based that decision on the info in this thread, to the best of my comprehension, that many Rollei films are based on the same Aviphot 200 stock and so I simply went with the one that was available and least expensive at the time I placed the order. I also noted based on the curves posted above that the Rollei/Aviphot seems to have somewhat more IR sensitivity than SFX200. (Though of course I might be misinterpreting.) That said, I suspect I'll also try SFX200 and make my own comparisons, especially since there is no published reciprocity failure data for the Rollei/Aviphot and so that may add some unwelcome guesswork to longer exposures.
As regards "encouraging flimflam," I absolutely see what you're getting at, but generally speaking I'm just not the type to put a lot of moral weight on small consumer purchases. Though I completely understand and respect those who do. I simply doubt my buying 5 rolls is going to make or break any business regardless of their shady marketing, especially when a bit of research (as evidenced by this thread) provides the truth about the underlying product, and that's what I'm paying for. Again, just my $0.02.
I bought an Ednalite 89B from filterfind.net, who I'd highly recommend.
I just found 40 sheets of 8x10 Efke IR. Now if all this bloody smoke from the US would bugger off, I might be able to use it!
What about the mirrors that go with it? Does that make it worse?
To all them folks below the 49th - Just kidding

HR-50 does indeed have good IR sensitivity. It also has remarkably fine grain, more so that any IR film I know. The Speed Boost technology is rumored to be a preflashing technique to reduce contrast, kick shadows off the toe.Is the Washi 400 NIR a repackaging of the old Agfa aerial 400 film?
There is no real datasheet on it.
How about Adox HR-50 Speed Boost? Is that also a rebrand?
The curve looks a lot like a smoothed version of the S80 curve and has a clear base suitable for SCALA.

Looks like a pretty nice film and they claim to have “Speed boosted” it whatever that is?
Team Adox do you have any comments?

I’d like to do the pre-flashing myself.HR-50 does indeed have good IR sensitivity. It also has remarkably fine grain, more so that any IR film I know. The Speed Boost technology is rumored to be a preflashing technique to reduce contrast, kick shadows off the toe.
