ken_dunn1 Posted October 25, 2009 Share Posted October 25, 2009 <p>I know this has been batted around on here before, but never really seemed to get a correct answer, so I thought I would revisit it. OK, Efke IR 820, 4x5, processed in Jobo reel/tank, rinsed with wetting agent, distilled water.....dirty. Redid and squeegeed, dirty and starting to scratch (I know this film is pretty easy to scratch so we can't keep rewashing it). Its like a film mostly, not specks but water marks. I have heard lots of people having problems but no solutions. It almost seems like the negs produce a scum or something of their own. The images are beautiful, but man I have never seen so much dirt. It looks like it was dropped in a muddy river and fished it out or something. I would really like to be able to use this film but I don't know what to do about the dirt. Also I did some other negs (Efke 25) at the same time and they looked much better. I think Tmax 100 spoiled me, that stuff is tough and always came out flawless (as far as surface imperfections). If we can't get it clean, how is the Rollei? I have heard its only some better, not perfect.</p> Link to comment Share on other sites More sharing options...
vinny_walsh Posted October 25, 2009 Share Posted October 25, 2009 <p>I've never had an issue with this film and dirty negs. Can you post a sample scan?</p> Link to comment Share on other sites More sharing options...

guido_h Posted October 25, 2009 Share Posted October 25, 2009 <p>I had similar problems with IR820 - see my posting and sample scan <a href="00UInV">in this thread</a> .</p> <p>It was argued at the time that the dirt was specific to the IR820 film, while the IR820 "Aura" film was supposed to be ok. I still have some "Aura" films in the freezer, but did not have time to test them and confirm this for myself.</p> <p>I tested the Rollei, however, and can report that it is definitely clean (just as a T-Max user would expect it), although it is quite curly after drying compared to T-Max 100. It also shows less Wood effect than the IR820. But on the other hand, it is two stops faster (I metered at ISO 400 minus 7 stops with Rollei, vs. ISO 100 minus 7 stops with Efke, both with R72 filter).</p> Link to comment Share on other sites More sharing options...

ken_dunn1 Posted October 28, 2009 Author Share Posted October 28, 2009 <p>Found a link that may be of help, not tried it yet but will. Looks like the trick is to soak in distilled water for a half hour at the end of the process. <a href="http://www.flickr.com/groups/efkeir820/discuss/72157614182374325/">http://www.flickr.com/groups/efkeir820/discuss/72157614182374325/</a></p> Link to comment Share on other sites More sharing options...
