Photo Forum / Film Photography / Darkroom / December 2004question about a Durst enlarger...
hi ! (excuse me for this question, but i'm a beginner) i have a Durst F60 enlarger. Naturally, there is the filter drawer, where i know i can put the contrast filters for multigrade papers, but there's also a red filter, which is integrated in the enlarger head, that can be used or not. when i use it, turning a little red knob, the projected image becomes red. i can't understand what's its task : maybe it is useful to project the image onto the paper without exposing it ? thanks for your answers, and excuse me for my english....... > filters for multigrade papers, but there's also a red filter, which is > integrated in the enlarger head, that can be used or not. > when i use it, turning a little red knob, the projected image becomes red. > > i can't understand what's its task : maybe it is useful to project the image > onto the paper without exposing it ? The red filter is supposedly so you can put the paper on the easel. Frame and compose the print. I never use it on the one enlarger that has it and I've never missed it on enlargers that don't. I figure sooner or later that red filter would get me in trouble. Nick : hi !

That's exactly what the red filter is for. On many enlargers, this filter is on a small arm that swings in and out underneath the lens. I know it's build into the enlarger head on a Durst M600, and perhaps on some other Durst models. This allows you to check the positioning of the easel before exposure. Warren B. Hapke wbhapke@prairienet.org : thanks for your answers, and excuse me for my english....... i ask this because my enlarger doesn't have the switch to turn the light on or off. i just insert the plug, and it turns on, i remove the plug and it turns off.... can i use this red knob as a substitute of the switch, or may i have problems ? thanks for answers !!! p.s. i don't own the timer !!! > : hi !

Using the red knob as a substitute for the switch is likely to cause minute vibrations in the enlarger head, which will degrade sharpness in the final print. In the US, hardware stores sell switches that can be spliced into standard two-wire power cords. I would assume that you could find something similar in Italy. If you have any mechanical ability at all, it's a very easy fix. Warren B. Hapke wbhapke@prairienet.org : > : hi !

Ciao Beppe, It is theorically feasible but I strongly advise you insert a switch in the power cord or, better, buy a timer, a very simple one is enough. You can find them very cheap on eBay, including pretty sophisticated timers (with analyzers which may be somewhat to early for you as you're a beginner) at very low prices (50 Euros and less) on eBay Germany. Or ask the italian photo newsgroup (it.arti.fotografia), chances are someone close to you sells one. Un salutone,  SignatureClaudio Bonavolta http://www.bonavolta.ch A timer is a most useful addition to any darkroom. If you get a Gralab 300 or equivalent you can use the same time for the enlarger and for timing processing of you film developments. Very useful if you want consistent repeatable results in the darkroom. If you didn't care about quality it's unlikely you'd be posting here so I'd invest in a timer (or multiple timers, I forget how many I own!).
