willscarlett Posted April 17, 2014 Share Posted April 17, 2014 <p>I just picked up some Rollei RPX 25 in both 35mm and 120. For the 35mm version, I'm wondering if this film has to be loaded in subdued light. With Rollei's previous generation of B&W films, even the non-IR films, there would always be some light leakage into the sprocket holes of the negative, which usually wouldn't reach into the area of any of the individual frames, but sometimes would.</p> <p>So long as I loaded the film in a changing tent, or inside of a backpack, things were alright. I suspect there was leakage because of the plastic canisters Rollei was using. I'm just wondering if the RPX films behave the same way.</p> Link to comment Share on other sites More sharing options...
Mike Gammill Posted April 19, 2014 Share Posted April 19, 2014 <p>I think it would depend on the base that the emulsion is coated on. I noticed some slight sprocket fogging with a roll of Rollei R3 that I shot a few years ago. </p> Link to comment Share on other sites More sharing options...
willscarlett Posted April 19, 2014 Author Share Posted April 19, 2014 <p>After I first noticed sprocket fogging with Rollei film, I always took to loading it in subdued light or total darkness. I'll just keep that up for now.</p> Link to comment Share on other sites More sharing options...
Mike Gammill Posted April 20, 2014 Share Posted April 20, 2014 Also noticed a few fogged sprockets on a roll of Rolleipan 25 I just developed. It's from a bulk roll. Maybe I need to load that in reduced light as well. Link to comment Share on other sites More sharing options...
willscarlett Posted April 21, 2014 Author Share Posted April 21, 2014 <p>Yeah, I've gotten fogged sprockets on Rollei Pan 25 as well. I now load all Rollei film in the dark, or subdued light. I've never had leakage issues with their 120 films tho.</p> Link to comment Share on other sites More sharing options...
simon_hall1 Posted April 23, 2014 Share Posted April 23, 2014 Rollei RPX25 is made by Harman/Ilford it should be a high quality product and you are less likely to suffer light piping. Many Rollei films are based on Agfa aerial film material which has a clear pet base and is very prone to light piping. The old Rollei Pan 25 was made by Efke and they had questionable quality control. Sadly Efke are no more hence the replacement with RPX25. Link to comment Share on other sites More sharing options...
willscarlett Posted April 23, 2014 Author Share Posted April 23, 2014 <p>Thanks for the info, Simon. I wonder if anyone will pick up production of Efke's IR films, or is there just not enough of a market for that?</p> Link to comment Share on other sites More sharing options...
