victoria_sky Posted July 23, 2009 Share Posted July 23, 2009 <p>Hi,<br> In the heat of a shoot I lost the seal with the identifying info for a roll of 120 Ilford film (either Delta 400 or HP5) which I sealed with a rubberband. Does anyone know if there is some sort of code on the backing paper which identifies the film? All I saw was the number 4.<br> Thanks!</p> Link to comment Share on other sites More sharing options...
lynn_washington Posted July 23, 2009 Share Posted July 23, 2009 <p>HP5 is also a 400ISO film. In 35mm, the processing is almost exactly the same, maybe a 30 second difference using HC-110 @ 68F. I would assume that the 120 would work the same way.</p> <p>Later,</p> <p>Lynn</p> Link to comment Share on other sites More sharing options...
ed farmer - mount laurel, Posted July 23, 2009 Share Posted July 23, 2009 <p>All that I can say is that I know that Kodak and Fuji print the film type on leader. I can't imagine that Ilford doesn't do the same thing. You should be able to unwrap one or two layers, in subdued light, and see if there is anything printed.</p> Link to comment Share on other sites More sharing options...

victoria_sky Posted July 23, 2009 Author Share Posted July 23, 2009 <p>There's a minute difference in development time between HP5 and Delta 400 using DDX. After rolling the film (last night before becoming aware of this issue) I was surprised to discover that there isn't any identifying info printed on the backing paper, but I realize after reading Ed's response that I could develop the leader to find out. I'll have to decide if the film is important enough to unroll, cut the leader, transfer to an empty tank, and reroll. Thanks for the responses!</p> Link to comment Share on other sites More sharing options...
greg_mikol Posted July 23, 2009 Share Posted July 23, 2009 <p>Actually, I think what Ed was saying is, once you get the film loaded on the reel, and sealed in the tank, look at the leader of the <em>backing paper</em> . The film type might be printed on the backing paper. It is for the Pan F Plus I have upstairs.</p> Link to comment Share on other sites More sharing options...
victoria_sky Posted July 23, 2009 Author Share Posted July 23, 2009 <p>Yes, I understand, and unfortunately no, it is not printed on the backing paper, which is what necessitated this query in the first place. Seems weird but there it is!</p> Link to comment Share on other sites More sharing options...
chris_waller Posted July 24, 2009 Share Posted July 24, 2009 <p>Like Greg, I've just looked at the trailing end of the backing paper for a roll of Delta 400 which I just shot and it's printed on there. Are you sure it's Ilford?</p> Link to comment Share on other sites More sharing options...
victoria_sky Posted July 24, 2009 Author Share Posted July 24, 2009 <p>Turned out to be Delta 400, which I suspected but wasn't sure of.</p> Link to comment Share on other sites More sharing options...
