  1. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    I don't know what that brown is at the base of the lamp. I'd probably get a new lamp.

    If found the most "on time" for my lamp was during composing and cropping. So, I have created tables for all...
  2. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    Looks like the 220V 2000W lamp. If this was a Durst-Pro 2000W conversion, then I suspect it is probably done well. Again, all my dealings with Durst-Pro were favorable, and Jens was helpful and...
  3. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    That would be another version of the story. That is, the EST2000 was modified to only power a 1000w bulb at 120V.
    I'd think changes to an EST2000 to reduce it to 1000W might be very difficult,...
  4. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    At first I thought the best thing would be for you to try an get a working EST1000 to match that CLS1840 head. But these things are so rare these days, maybe getting your two units working safely is...

    Remove the two thumbscrews and the bar which holds the lamp will lift out. The lamp is not attached to the reflector.

    Here are the pin-outs for the connector (EST2000 on LEFT and EST1000 on RIGHT). It does look like they may match up. Still scary.

  7. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    Ok, this is what I see:


    The chassis is a L184

    The head is CLS1840 1000W

    The power supply is for the CLS2000 2000W.

    The fan is rigged up to suck.

    Did you start a thread on your enlarger? Otherwise, pictures please, post them here! One little mistake plugging things in wrong could lead to tears!

    The 1000W Colamp 1840 will likely fry in an instant at 240V! I don't think it will fit in the socket anyway.

    Why do you think it is too bright, The CLS2000 is only one-stop faster than the...
  10. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    The blowers on the CLS2000 are pretty loud, hard to miss. Like two hair blow-driers.





    Check you bulb. It should be a 1000W 120V Colamp1840 like this.

    Here is a CLS2000 setup on the "Footprints" brokerage site. Not too bad at $4000USD. I got just about the same setup with the Negateil, the mixing boxes and a box of lenses with around $2000USD...
  15. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    Yes, I found the CLS1840 schematic and it only shows the single Lufter (fan).

    Out of curiosity does the CLS1840 have this opening that blows on the negative holder?

  16. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    From what I can tell, the CLS1840 is similar to the CLS2000 pictured here.

    When you get the CLS1840 you should get the EST1000 with it and some light box diffusers. The light box diffusers are in two parts, upper and lower. You will need a timer, as the timing unit is...

    Updating the answer to this question. I found the following quote in one of my Durst L1840 manuals:
  21. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    The below is a quote from the technical literature.
  22. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    I believe the CLS heads mount with the same 4 bolts that hold the condenser head in place.
  23. Re: Contrast control with Delta 100 and Rodinal

    Since this is posted in the darkroom section, usually one would match film development to the printing paper used. There are many good books on the subject.
  24. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    For every negative to paper distance that can be focused for an enlargement, a reduction can be focused at the same negative to paper distance.

    This is easier to experience with 8x10 enlargers,...

    Re: 4x5 enlarger

    Google is only good if you already know the answer. The second dark ages is already here. I'd recommend a book on photography. There were many published and not all burned yet.

    Re: Deardorff 8x10 V8 repair questions

    I have used both epoxy and titebond for view camera wood repair. If the wood is just cracked I'd use titebond. If the wood is soft or missing volume, I'd use epoxy.

    Re: Rodagon-G 360 for enlarging 5x7 12 times

    Seems odd that you would not be happy with the results of the 210 rodagon and that your test of the different lenses showed different results for each lens of suitable performance for the task. I...
  32. Re: Scanner, enlarger, or contact printer? Which one and why???

    I won't comment on computer graphics, but an optical enlarger allows reductions, 1:1 and enlargements, so that would be the most versatile tool for printing large format negatives.

  34. Re: Lens Advice / Opinion: Consistent Look (or thatís not real)

    Color, not visible in B&W
    Contrast at maximum
    Distortion unaffected by aperture
    Resolution at maxium
    Flare at minimum
    Bokah, not a word I have ever heard from anyone viewing my work.
  35. Re: Lens Advice / Opinion: Consistent Look (or thatís not real)

    I stop down my lenses so they don't have a 'look.' I prefer the lens to be a transparent part of the reproduction cycle.

    Re: Durst 138 which color heads can work?

    If the enlarger you pictured is in good shape, consider getting that and replacing the condenser head when you find the color head you want. I got my L1840 with an Aristo head and I used it that way...
