From: "Rolland Elliott" To: infrared@a1.nl Subject: IR film formats & the Death of 4x5 IR film by Kodak. Date sent: Fri, 26 Nov 1999 16:58:33 EST Send reply to: infrared@a1.nl To answer some past IR digest questions: Yes, I sell cut down IR (B&W & COLOR) in 120 & 220 formats. Email me OFF LIST if you are interested. Cost is $20 for 120 and $25 for 220. To Answer one of WJ's past questions: Yes, B&WE IR film is available in 9.5 inch bulk rools. I forgot the exact length, I think it was 250 feet. Anyways at a cost of approximately $1300 per roll, no one is gong to buy it and split it down (not even me!) so for all practical purposes this is not a solution to Kodak's discontinuation of 4x5 IR film. WJ also mentioned that there was an article on his web page detailing someone's use of this 9.5" bulk film & having problems with a pinkish base fog. I'd like to respectfully state that the article on your page talks about someone using 9.5" AEREOCHROME COLOR IR film and CROSS PROCESSING IT in C-41 chemicals, not B&W IR film. My personal opinion is that this pinking base fog on CROSS PROCESSED COLOR IR film isn't a "problem" or strange occurance. I've cross processed (which means developing it in C41 as opposed to E-6 chemistry) Color IR film and you get a pinkish base fog. If you cross process any film you get wierd colors and a base fog 99% of the time. So it is no surprise that Color IR film exhibits this trend. Lastly the other IR formats that Kodak provides for anyone's interest: Kodak's L-9 professional photographic catalog says Kodak sells the following: CAT No. Size mmxft Spec. No. Letter Code Sales 160 4149 35x150 417 HIE 1 Roll 169 0841 70x150 494 1 Roll The street prices for this film are a little cheaper. According to KODAK, The 35mmx150ft film has Bell and Howell (BH) perforated both edges while the 70mm roll has Type II performations - in accordance with ANSI PH1.10-1976. The 70mm film comes in a 4-mil Estar Base. Past users have reported that the 35mmx150' Bell & Howard performated film has the same perforated edges as standard 35mm film. Why Kodak makes it sound like it won't work in regular cameras is a mystery to me. And as others have noted you can get Kodak to manufacture any film format you desire, as long as you purchase a certain mimimum order, which is always several thousand dollars worth of film, which makes it practially useless to do, unless you want to set up a business selling the stuff. Thanks Rolland P.S. You can get a copy of Kodak's 1996Professional Photographic Catalog Publi cation #L-9 by calling them @ 1-800-242-2424. It has lots of great info. on all the film, chemicals, and papers they make including infrared films.

Yes, I checked with Glazer's in Seattle, the 5" rolls that were in past versions of L-9 are no longer listed in the current edition. Guess there wasn't even enough demand to keep them in teh catalog as non-stocked options. >According to KODAK, The 35mmx150ft film has Bell and Howell (BH) perforated >both edges while the 70mm roll has Type II performations - in accordance with >ANSI PH1.10-1976.

Why Kodak makes it sound like >it won't work in regular cameras is a mystery to me. I can perhaps clarify that a bit, having gone through several of the 150 foot rolls. B&H perforations have a very slightly different shape than Kodak standard perforations. If you lay one on top of the other you can see the difference, but I've never had a 35mm camera that failed to take the bulk HIE, feed it properly, count frames correctly, etc. The perforations are in the right place, and almost identical -- there's probably more difference between Kodak standard perforations and other brands of standard 35mm film. I suspect this might be a problem in the other direction -- the more precise registration of film in a movie camera might not accept standard 35mm still film perforation. But the bulk stuff does work fine in my Olympus, Minolta, and Pentax cameras. As for the earlier comments on the dating of 70mm, I have a roll waiting for me at Glazer's, and I'll let you know what it says. But I've used HIE that was past-dated when I bought it, and as long as it was cold stored the whole time it should be fine anyway. I'm currently using bulk HIE that expired two years ago. It had expired when I bought it, but had spent its entire life in a refrigerator, and I've kept it frozen since then; it gives exposures identical to factory-fresh HIE. -- Josh@WolfeNet.com is Joshua Putnam / P.O.
