j._patric_dahl_n Posted August 20, 2001 Share Posted August 20, 2001 I have developed a couple of rolls in Mimosa No. 3, a Catechol developer with Soda as alkali. It works great, and got very nice results with Tri-X, Efke R100 and Agfa APX100, but with Efke R50 I get strange lines and marks on the negatives, just like it was raining in the scene I took pictures of, or as if I scratched the emulsion when wiping the water from the wet film before the drying. <p> I made an illustration you can look at: <p> http://imagehost.auctionwatch.com/preview/bl/bluebottle/.mids/negfel.jpg <p> Efke R50 is a thin emulsion film, but I have never had any big problems with it before. Can it be an agitaion problem? I inverse the small tank three times every half minute, but when fixing I rotate the spindle instead. <p> Sorry for my bad english, but at least I try! :-) Link to comment Share on other sites More sharing options...
j._patric_dahl_n Posted August 20, 2001 Author Share Posted August 20, 2001 I saw that one of Windisch recipes with Catechol has less alkali for thin emulsion films and more for thick emulsion films. Is this maybe the problem, I had too strong alkali in my developer? Hmmmm... Link to comment Share on other sites More sharing options...
david_foy1 Posted September 1, 2002 Share Posted September 1, 2002 It is unlikely to be the developer. More probably a quality control problem with the film, either during manufacture or processing. Static? David Foy Link to comment Share on other sites More sharing options...
