Hi guys, The 100W lamp of my Durst M605 Color enlarger recently died away and I got a new one from Philipps (also 100W halogen) . When I first tried to make prints again, I noticed, that the projected image was quite a bit darker than it used to be with the original lamp. Also Changing the filter settings and moving the filter "in" didn't result in the desired effect. When I turned the Magenta to 130 for example, it looked like it really was set to 20 or something. I only get a real effect by turning the filter at the back of the enlarger, the "supplementary filter" in, but I'm not sure if that's the right way to handle this. I also exchanged the transformator for the enlarger but it didn't change the situation. Any ideas on this? Thank you very much!
