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

    The cosmetic bellows on my column was pretty messed up but I was able to repair it:

    All the images from the first part of this thread are long gone. I'll repost them as I can. Since we are in cleaning up, here are some before and after pictures from over ten years ago:

    Sticky: Re: New Forum--populate it!

    Now for a very stupid question. What is encompassed in the "Wet Plate" nomenclature of this sub-forum.

    The reason I ask, is that as a photography minor, I was always intrigued by statements that...

    Sticky: Re: New Forum--populate it!

    I have only done wet plate once. But it is nice to see a sub-forum where I can come in case I want to do it again.

    Oh, I see. You have replaced only the lamp with the LED panel. The condensers are still in place. Nice solution.

    Tin can had done some experiments with LED panels too, but from what I recall he...
  7. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    I'm not that familiar with the condenser head. Can you post a picture of the light panel and how it is installed?
  8. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    My ceiling cuts off about 2 inches of maximum height. The thing about 8x10 enlarging is with the relative small magnification ratios, that 2 inches is the difference between a 30" and a 40" print...
  9. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    Again, I don't have that gear in my enlarger, but I still don't see why it can't be 3D printed. This guy 3D printed a gear for a friggin lettuce washer.

    Yes that would be correct to have the two convex surfaces toward each other.
  11. Re: Seeking Ideas For Replacing Film Holder Labels?

    Every time bulbs for that head are discussed I always post the same thing. Consider using an diffusion disk as the target for the condensers (rather than the globe of the hard-to-find lamp) and...
  13. Re: Durst L1840 Enlarger 8x10 10x10--Everything you wanted to know...

    Condenser focal length and lens focal length need to be coordinated via the chart in the manual to ensure even distribution of light. The way I think of it is the condensers are focusing the light at...

    What head/bulb do you have? There were 5 different Durst heads and many other brands fit too.

    Re: How To Use Stouffer Step Tablet?

    Contact it to the paper tightly so no light leaks around. If light leaks around the dense strips this will mess up readings. If you just want to measure contrast, expose so the entire scale fits in...

    5/64 and 2mm are pretty close. In fact my 5/64 driver and 2mm driver measure the exact same (2.00) with micrometer. If a 1mm is too big you might try 0.9. I got mine from MIP.
