Kip Kubin Posted July 13, 2011 Share Posted July 13, 2011 With the purchase of a camera the seller threw in a large amount of film stock. Mostly 50D/250D but there are a few cans of 500T and 320T that concern me, All film was stored in a refrigerator and doesn't look very old... how old he didn't know though. I don't mind some fogging or artifacts of age as I can use those for experiments and tests... I just need to now which stock is OK and how much to push to get a usable image. So that leads me to my question Can someone walk me through the correct method of submitting film for a strip/clip test? I have several rolls of several types of 16mm film and don't know how to submit the film for testing. I've read that 2 ft from can. One strip for each batch of film cans. How do you label these strips and how do you package them? Stocks Some numbers may indicate age... I'll start researching that now. 50D 7245 50D 7201 250D 7205 250D 7246 500T 7279 TRI-X 7278 320T 7277 Also, on a side note is there any way of reading the numbers on a can of Kodak film that will tell you the year it was manufactured?

Antonio Mendonca Posted July 13, 2011 Share Posted July 13, 2011 Hi Kip. Its normally easier to just send in the entire roll (in your case all the rolls) to the lab and let them handle it. Link to comment Share on other sites More sharing options...
K Borowski Posted July 13, 2011 Share Posted July 13, 2011 Or just send us five feet each, and refrigerate, safely store the rest of your film! Send me five feet each, and I'd be happy to run it for you for $5 ea. That's the cost of processing only, not anything for my time, if you are in the U.S. What we do is shoot them in a still camera, a grey card and change exposure up and down in 1/2 stop increments. We also shoot a bright blue (yellow patch) but that is more for our own internal testing to make sure all the silver is removed from the film in processing. So start grey, you need clear (D-min), D-max ( just take the lens off the camera point at the sun or bright light, and open the shutter for a couple seconds, and I like to go in half stops a range from -3 to +5 or 6. You can shoot a Gretag McBeth, but it isn't necessary, the grey card tells us just about everything. A lot of labs just read base fog on the film too without exposing a grey card or usually a step wedge onto it. That tells you a lot as well.

Kip Kubin Posted July 14, 2011 Author Share Posted July 14, 2011 K Where are you? What is your company? Thanks for the responses Kip Link to comment Share on other sites More sharing options...
David Cunningham Posted August 14, 2013 Share Posted August 14, 2013 BUMP... I'm curious who you are too! :) I'm looking to do the same with 7291 that I picked up on ebay... want to get the best idea on how best to shoot it, assuming it's any good at all.

Mike Tounian Posted August 15, 2013 Share Posted August 15, 2013 I'm not sure that you can snip test (or process) that negative anywhere, it is the old ECN process that hasn't been used since the late 80's. ECN-2 is, from what I have been told, a totally different process and not compatible with ECN. Link to comment Share on other sites More sharing options...
David Cunningham Posted August 16, 2013 Share Posted August 16, 2013 Interesting. I was told it was actually ecn2, that ecn (1) went away in the early 70s. I confirmed with spectra that they could process this stock as ecn2. Link to comment Share on other sites More sharing options...
Mike Tounian Posted August 16, 2013 Share Posted August 16, 2013 I saw your other post while combing through the archives. If you look at the photos of the box from ebay, you can clearly see that it says "ECN" on the box cover, not ECN-2. In support of that, if you look at the wiki entry for Kodak Motion stocks, 52/7291 is listed as an Eastman Negative stock, which is ECN process. When they moved to EXR in 89, they changed to ECN-2. But we all know how inaccurate a wiki page can be, so I can't say that is 100% certain. We need someone who works for a lab to chime in. Actually, I'm going to Fotokem tomorrow, I can talk to Walt Rose about it and see what he says. He dealt with USC 16mm projects from the very early 80's on, so he probably knows all of these stocks and what they are (or are not) capable of being processed in. All the same, PM me and get my email address, so you can email me photos of the cans and I can show them to Walt and see what gives. Link to comment Share on other sites More sharing options...
David Cunningham Posted August 16, 2013 Share Posted August 16, 2013 This shows it as ECN-2: http://www.taphilo.com/Photo/kodakfilmnumxref.shtml Link to comment Share on other sites More sharing options...
David Cunningham Posted August 16, 2013 Share Posted August 16, 2013 According to the kodak history pages (on kodak.com) ECN-2 became the standard in the mid 70s. Link to comment Share on other sites More sharing options...
