Thanks for the reply. I did a looking since I posted and found the Efke had an IR film. Was it any good, for those that shot it?

So I'd conclude that from what you say Sirius that HIE depended on chemicals that require billions of dollars which presumably the Rollei and Ilford films do not? Thus the edge in terms of speed and no need for more than a red 25 for HIE is only possible by means of chemicals that cost billions and it is this that distinguished HIE from the likes of Ilford and Rollei and the late but lamented Konica?
If I have got this right as my interpretation of what you said then can you refer us to this source of information? It would be interesting to know what these chemicals are and why they cost billions
Thanks

There was another IR b/w product from a company other thank Kodak, Rollei, and Ilford. Do you know who offered it? And was it any good. I just can't remember the manufacturer.
Most Efke products weren't bad until their emulsion making apparatus slowly began to break down towards the end. The emulsions they made had been largely unchanged since the early 1950s. They had somewhat different characteristics from later (late 1950s onwards) more controlled crystal growth emulsions.
Konica also used to make an IR film.
Thanks for your reply Sirius but I have to say it doesn't really answer my question which was: Was there a chemical or chemicals involved in Kodak HIE that made it different from other IR films and which are not now available to these other companies simply because only a government with the resources of a large nation of taxpayers could afford them which allowed Kodak to sell its film to general consumers at a reasonable price. In effect it sounds as if the taxpayer in effect subsided Kodak HIE consumers?
So what is the source of your knowledge and what were these very expensive chemicals? Thanks

Hey, even Efke could make post 800nm IR film in their poverty stricken, worn down fifties grade facilities.The most important difference about HIE is that the high speed, highly mechanized quality control techniques used with other films, which used IR sensitive examination techniques, couldn't be used with HIE.
Any run of HIE involved a major reset of the plant, a lot of additional quality control work, significant wastage and general disruption to the profit making processes.
I expect the requirements of the major users of HIE - the military and some industries - may have required even narrower tolerances than regular film.

It can’t be that difficult.
Here we go again. HIE and IR Ektachrome were fully paid for and kept in business by the US Government as a Nation Resource. It paid for maintaining the supply of necessary chemical in the proper form. Those chemicals in the proper form are no longer available. To bring back those films are not economically feasible unless your personal bank account has billions of dollars. This has been posted many times on APUG and Photrio. Give us a break and dream about feasible films.
Nope. D-76 was perfect.
This HIE talk is making me want it even though I never missed it that much. I only shot a few 35mm rolls of it way back when I first got serious into photography but one of the first B&W pictures I made which I honestly thought was very good was on one of those rolls and I had a lot of fun working on the print.
At the time I took the film for for granted - didn’t know the ins and outs of the technology involved and difficulty in making it. I thought it was just another film sensitized differently.
It would be cool to have it back but I feel like it is too much of a “special purpose” type of product to appeal to enough casual users today, especially since you had to be a little more careful storing it, loading it, focusing etc., and of course some guesswork and bracketing was involved with exposure.
Well, I’ve heard enough. I think it’s settled. HIE is coming back!
I'd be curious to know if Kodak has looked into it, since starting this film revival.
Remember to report back that Andrew is willing to buy the entire stock of HIE if produced. (Of course, that won't help the rest of us.)
To add perforations?K-98 Mauser
