Istvan Ordog Posted January 1, 2023 Share Posted January 1, 2023 Hello, Can you please help with identifying the price/worth of a stock of unopened, expired 16 mm Gevapan films? See picture below: https://drive.google.com/file/d/1rZTLS7R3nGofYnKOR0l6mPnnBkLlOEkV/view?usp=share_link Thank you! Link to comment Share on other sites More sharing options...

Dirk DeJonghe Posted January 14, 2023 Share Posted January 14, 2023 Gevaert Photo Producten (Mortsel, Antwerp Belgium) merged with AGFA (Leverkusen, Germany) in 1964. So by deduction, this film must date from before 1964. Probably very heavily fogged by cosmic rays. 1 Link to comment Share on other sites More sharing options...
Premium Member Aapo Lettinen Posted January 14, 2023 Premium Member Share Posted January 14, 2023 I think the expired very old stocks can be worth something like from half of the new FomapanR100 roll price to the full FomapanR100 roll price. But it needs to be shootable so the approximate condition of the stock needs to be known, otherwise it is only worth the collector value of the box and the film can. You should either shoot a roll or two or take clip tests out of couple of randomly selected rolls. Develop them and see how they turn out. If there is an image of any kind, then someone will probably buy them if the price is right ? Old film can have been in unknown storage conditions for decades and there is no way to know if it is shootable or not without actually opening some cans and actually testing it. I have purchased some old 16mm rolls in the past which were fuzed to solid blocks and could not get a single feet of film out of them, it can really get that bad is stored incorrectly in too warm temperatures so the only way is to test some and then you will get much better price out of it too ?

Mark Dunn Posted January 14, 2023 Share Posted January 14, 2023 I think this should be regarded as a curiosity. You have two different stocks, 30 and 36, of different speeds so they might both need testing, and even if successful you can't assume that any other can is in good condition. Assuming you don't plan to use them yourself, as Aapo says they are a collector's item. Every other aspect of production (process, scan) would be at full price, so there would need to be a heavy discount for the risk. Unless the nature of the project takes it into account.

Doug Palmer Posted January 14, 2023 Share Posted January 14, 2023 Some of the really old stuff can give interesting effects. Bear in mind also it's likely there's a considerable reduction in the iso speed. If nothing else there is plenty of blank leader for someone, and some useful spools and cans.

Istvan Ordog Posted January 15, 2023 Author Share Posted January 15, 2023 Thank you for all the comments, will try to test them and see. Have a nice day! Link to comment Share on other sites More sharing options...
Doug Palmer Posted January 15, 2023 Share Posted January 15, 2023 Just a metre cut off (or examined in a dim place) should reveal if the film is brittle or warped. Or whether shrunk, by comparing alongside a piece of white leader. Link to comment Share on other sites More sharing options...

The question is whether it's too shrunk to run in a camera, and you could only check that by running it. Up to 1/4% runs with care on a Steenbeck, albeit a bit noisily. As you say coated white leader doesn't usually shrink, that's what I use as a gauge. I think polyester sound spacer is immune, but lightstruck black leader isn't. An easy way is to cut 100 frames as a gauge, and remember that a perf is one-fifth of a frame in height, so if the 100 frame length of film is 1 perf shorter, it's shrunk by 1/5%. Not that you need to know the percentage, just if it runs OK. But you sometimes find out things you don't need to know on this forum. Link to comment Share on other sites More sharing options...
