Photo Forum / Film Photography / Darkroom / July 2004Durst cls 305
Hi everybody, i bought for my daughter an old second hand enlarger with Durst cls 305 color head, so she can practice an develop her first b&w pictures by herself. But i can hardly find any manual about this model, and it would be great if someone could give me a few informations. This would badly help us. And specially what for is the button in/out called "B.filter white light" in the front of the enlarger. And the second on the left of the head ? Thanks for your help. lou U?ytkownik "Lou" <lou36@hotmail.com> napisa? w wiadomo?ci > Hi everybody, > i bought for my daughter an old second hand enlarger with Durst cls 305 > color head, so she can practice an develop her first b&w pictures by > herself.

I could scan it and send to you as .jpg files, if you want to. > And specially what for is the button in/out called "B.filter > white light" in the front of the enlarger. AFAIK, this turns off the color head and lets only white light from the halogen bulb flow through.

First of all go to the Durst website and email them about a manual. At worst they'll say no but if they have one in stock they'll likely send it to you. http://www.durst-online.com/uk/service.asp The white light filter likely moves the filters out of the light path so you can focus without the filters. It's alot easier then rotating filters in/out. Set the filters turn on the enlarger then push the button. Do you now see white light?

When I request one for my enlarger they had it here in about one week. Haven't they at least answered your email? > Well, no, as a matter of facts, the swich on the left side does this (remove > filters) , but the button on the front marked "B. filter white light" adds > a kind of filter that attenuates the light when turned on. Neutral density then?

Thank you. I'm learning. But i can't find what B is standing for... Best regards Lou > But i can't find what B is standing for... It stands for Blende. That's Blind in english. That's iris diaphragm in photo slang. In your head the lever pulls in/out a metallic mesh in front of the path light to dim it without altering Kelvin degrees of the source.

That sounds like what we call a "neutral density filter." It reduces total light without having to stop down below optimum lens opening or change the color temperature by dimming the bulb. Useful when you want a long enough exposure to do some dodging or burning, or as part of the total filter setting to maintain constant exposure across a range of multi-contrast filtrations.
