Filip Syczynski Posted October 15, 2007 Share Posted October 15, 2007 Hi! A few days ago I bought some older (2004) 35mm film stock, each for just 10£ so I thought that I wouldn't lose much by just risking it (3 x 400ft Kodak Eastman 250D 7297 1R 3 x 400ft Kodak Vision2 100T 7212 1R ). I wanted to ask, if there is a chance of maybe testing the stock (just some 20ft?) before shooting anything on it? (not to gather all the crew, actors etc. and then the footage would come out black after processing... that would be a disaster). Link to comment Share on other sites More sharing options...
Premium Member Tim Carroll Posted October 15, 2007 Premium Member Share Posted October 15, 2007 In the past I've done a "clip test" (I think it's called). Shoot about ten to twenty feet, send it to a lab and have it processed, and then look at it with a light table and a loop. -Tim Link to comment Share on other sites More sharing options...

They'll take a few feet off your roll and process it. Then they measure the base density and then give you a figure. I vaguely recall more than +10 in R G or B wasn't good. Of course...it never stopped me from shooting with it....:-) jb Link to comment Share on other sites More sharing options...
Filip Syczynski Posted October 15, 2007 Author Share Posted October 15, 2007 Thank You for your help! I'll do the tests ASAP Link to comment Share on other sites More sharing options...
Jonathan Bowerbank Posted October 16, 2007 Share Posted October 16, 2007 You don't even have to shoot anything, just cut a few feet off and send it to the lab for the clip test. They'll test its density and let you know what sort of condition its in. Link to comment Share on other sites More sharing options...
A. Whitehouse Posted October 16, 2007 Share Posted October 16, 2007 Just be aware that the dip tests are very precise and Ive shot whole shorts with few problems on stock that was declared unusable and no good at the lab. If your going a TK or Digital route it isn't as much of a big deal. On my own project I made sure to shoot the first 30 feet of each roll for make-up, filter, lens tests etc. It was a pain in the ass but my stock had been in a fridge for 5 years +. It was interesting shooting on 5293 in a world of V2s. While I knew that the stock had been well taken care of before it had hit my fridge (i scored it from a really large production) age does take its toll and it showed up in grain on some rolls. Anyway, don't give up hope if the tests come back negative but go into this with your eyes open. Sasha Link to comment Share on other sites More sharing options...

You are aware, I hope, that these numbers refer to single perf (1R) 16mm stock, not 35mm ? -Sam Link to comment Share on other sites More sharing options...
Andrew Brinkhaus Posted October 25, 2007 Share Posted October 25, 2007 Another quick test to see the results of the stock would be to just buy a cheap bulk loader, and cut a foot or so and load it up in a 35mm photo canister, and shoot a roll on a still camera. Get it developed wherever, and check your prints when you get them back for any major damage/defects to the film. Link to comment Share on other sites More sharing options...

Most motion picture film has a coating that will RUIN a "mall mini-lab." Do NOT develop this film at a local shop. The coating plugs the plumbing system. It coats big bucks to fix! The lab owner will hate you, and might want you to pay the thousand of dollars it costs to make the repairs (ie. take you to court). :blink: Link to comment Share on other sites More sharing options...

If that's correct, then it should be possible to pull the Remjet off exposed film in a simple home darkroom process, dry the film, reload it into the still cannister, and then take it to the minilab machine. Anyone ever try this? (Turns out this isn't correct, see following information) I found the thread discussing DIY processing: John PytlakFeb 13 2006, 12:10 AM (Paul Bruening @ Feb 4 2006, 02:57 PM) <{POST_SNAPBACK}>Karl, thanks for great info, What's the best way to remove the remjet backing? Will it come off with just water jets or does it require some form of physical contact? Would a series of sponges do the job? What about a soft centrifugal roller from a squeege works? The Kodak H-24 ECN-2 processing specifications include a high salt alkaline prebath to soften the rem-jet (but leave it on the film in the tank), then a directed water wash-off (to remove most of the rem-jet and not have the particles get back on the film), and finally buffing with more water wash off (to remove the residual binder). Doing it by hand (in total darkness) will likely remove most of it, but it is difficult to not have some particles get attached to the film as your sponges/buffers load, and some gets pushed through the perfs.
