Enlarger question at rental darkroom
The following enlarger setups are available at my local rental darkroom:
Omega D5XL (Super Chromega D Dichroic II) w/ Chromegatrol Timer Omega D5 XL w/ Saunders LPL Digital Timer Omega D5 XL w/ Beseler Audible Timer Omega D5 w/ Beseler Audible Timer Open Station / Workspace Omega D5 XL (Super Chromega D Dichroic II) w/ Omega Chromegatrol Timer Omega D5 w/ Beseler Audible Timer Beseler 23C III Dichro Colorhead w/ Beseler Audible Timer I'm unfamiliar with the different heads, are the dichroics appropriate for B&W? I haven't received a response regarding the non-dichroic setups yet. This is a B&W only darkroom so I assume they're ok. I'm only familiar with the Beselers so if the dichro is ok I'd probably use that 23C III. Thanks, Greg -- http://lodesertprotosites.org Dethink to survive - Mclusky |

I'm only familiar with the Beselers so if the dichro is ok I'd probably use that 23C III. There are three kinds of lights used in enlargers. The most common is an incandescent lamp, similar to the ones that are (or used to be) in your home. Dichroic heads are incandescent bulbs with stepped filters between them and the negative. Since they are designed to always be the same color, they are often low voltage bulbs with electronicaly controlled (stabilized) voltage, so the color and intensity does not vary. With the filters set to 000, they are just brighter lamps as far as B&W printing is concerend. They may also have a slightly higher color temperature as they tend to run "hotter". Again no problems. You can also use the dichroic filters to make the equivalent of variable contrast filters for variable contrast paper. Charts can easily be found on the web. Make sure to get the right ones for your paper. AFAIK all modern papers use the same ones, but different companies recommend different settings. If I were you, I would pick one enlarger and stick with it. That way any variations between color heads, bulbs and filters won't affect you. Geoff. -- Geoffrey S.

Enlarger question at rental darkroom
It's all good equipment and the dichro gear is a nice way to deal with
variable contrast papers. There is much information on the filter use for this on the net. If you have trouble finding or understanding what you find, let me know and I'll email you some charts to get started. If the enlargers are well maintained and aligned, the lens quality and your focusing technique will be a big determining factor in the sharpness you achieve. With these nice enlargers, my guess is that there are some decent optics attached and your learning should be initially on learning your materials and understanding tones, etc. Have fun and don't be afraid to ask for help. It can be a bit confusing anf frustrating to sort it all by yourself and it becomes much more enjoyable once you've gotten the basic skills mastered.

I have my own Ilford filters that I bought when I took a class, and I'm way more familiar with using them than I would be with using a dichroic head. I don't want to waste too much time relearning if I don't need to. Here's the lenses that they currently have: Nikon EL Nikkor 50mm 2.8 (2) 63mm 2.8 75mm 1.4 80mm 5.6 105mm 5.6 (2) 135mm 5.6 (2) Rodenstock Apo-Rodagon 150mm 1.4 Rodenstock Rodagon 50mm 2.8 (3) 105mm 1.6 Rodenstock Rogonar 90mm 1.4 Schneider-Krauznach 50mm 1.4 My negs so far are 35mm, 6x4.5, and 6x7.

Thanks, Greg -- http://lodesertprotosites.org Dethink to survive - Mclusky Variable contrast paper usually has color head settings listed for various contrast grades. The color head works fine but you may lose the constant speed property of the fixed filters and, on some heads, the extremes of contrast may not be available. You can use filters by setting the color head for minimum filtering although you may have a problem finding a place for the filters. Once you get used to the color head you will find it convenient. The D5 is an excellent enlarger, the XL means Xtra-Long and refers to the support column. I can't tell you anything about the various timers. -- --- Richard Knoppow Los Angeles, CA, USA |
