fernando_garcia4 Posted September 27, 2020 Share Posted September 27, 2020 Hello, I have an old DURST CM 50 color analyzer. I never used it. But today I have try to know how to use it. It hasn't user manual. I Insert four LR44 batteries, and it seems to run. I think this CM 50 can hel to to find the exposure time when I enlarge copies. I try to find the user manual in google, but I don't find it. Could somebody help me to get this user manual? Thank you very much. Link to comment Share on other sites More sharing options...
ericphelps Posted September 28, 2020 Share Posted September 28, 2020 I didn't have much luck searching either. This fellow on Photrio had one and would send it out to other members there, but went silent after a request from 2014. Good Luck - Why do I say things...

rodeo_joe1 Posted September 29, 2020 Share Posted September 29, 2020 (edited) I thought I had one, but just Googled the thing and it's nothing like the Durst analyser I was thinking of. Sorry! Looks like it just clips onto the enlarging lens, so it won't be any use to read exposure times for B&W printing, if that's what you had in mind.

glen_h Posted September 29, 2020 Share Posted September 29, 2020 Interesting. I have a color analyzer that I haven't tried using (partly because I haven't been interested in any color printing since I got it used.) As I understand the one I have, you put a diffusing filter over the lens, such that it reads the average color (and intensity) of the whole print. But I don't have that filter. I don't know if the CM50 needs such a filter, though. In the beginning of Unicolor, they had a system for determining the color balance with a diffusing filter and set of filters in what looked like the image of a flattened cube. You then expose a print through this, and choose the one that came out with the least color offset. Here is a picture of the box: Camera House In any case, a common way to do color metering is average over the whole scene. -- glen Link to comment Share on other sites More sharing options...

It gets the name from some HTML tag, but I don't know which one. I have often been surprised with the names it comes up with. -- glen Link to comment Share on other sites More sharing options...
