Thank you Monty! This is exactly what I need, and is enough for me to make a set of temporary (not adjustable) stand-ins until I can figure out how to make an adjustable one.
I am totally...
Thanks Monty, pictures of the item (what do those knobs do?) and in camera would be very helpful...
I am looking for a few pictures or a description of the Ebony bellows support. Some of the larger Ebony cameras came with an adjustable bellows support device. I have seen pictures of these on...
I had a 19 3/4" Kodak Ektanon (f10) that came with a nicely made 90 degree prism for just this purpose. I used this for a bit with 11x14 and it worked as expected, but found that I was still...
To my knowledge Daguerre and Niépce (and maybe Talbot) began their research using a camera obscura. Some of these had mirrors which would allow a piece of paper placed on top of a piece of ground...
I will happily take one!
I don't know, sorry, I don't have a 12" lens to try...
Would love to see the files on Thingiverse! Not sure of Fusion360 files are sharable, but that is good too!
My Eastman 13.5" f3.5 barrel measures 3.8705" (just a hair under 3 7/8"), so the same as Tracy's 12" f2.5 shutter. A caveat: My calipers are cheap and my technique is poor. But I have two sets of...
That looks right to me. How much staining in the rear element?
I will check this weekend! Just noticed another note from about the same time which said that the 610mm Aero Ektar (F6?) also has the same barrel size. This might be a hallucination, but I can...
About 20 years ago I pulled a (big) box of four of them out of a dumpster next to a camera store (somewhere in Queens) that had closed, along with a few other choice items. Two were marked Eastman...
I am not sure how you would actually see one in an image; The hole and screw are between the shutter and board, so wouldn't be visible unless you removed the lens.
To be clear, the head of the...
Hahnemühle Platinum Rag?
That is an interesting point. I notice that Renaissance Wax does not work so well on my current paper of choice, Legion Revere, and works better on other papers I have used. Have to think about which...
I have been biking with a 5x12 around town. I use an extended bike as mentioned above with huge rear bags. I recently upgraded to an eBike with fat tires which is really nice, but makes me feel lazy.
It is possible to abrade the surface when applying wax and remove some of the "delicacy," so you do need to do so carefully with a soft cloth.
I have been using Renaissance Wax for many years on Kallitype prints, and have been pleased with the results. Previous to that I used beeswax and lavender oil, as Paul described above. I tried a...
What do you use to clear? Citric acid might be ok, but EDTA is not (easily) biodegradable.
There is a lot about UV passing lenses on Klaus Schmitt's blog: https://photographyoftheinvisibleworld.blogspot.com/2011/01/uv-lenses-tested-good-for-uv.html
There is also a database of macro...
Daguerre used concentrated (and maybe heated?) sea water initally, but it was slow and problematic, even with the easy-to-clear Daguerreotype plates. It would likely take hours with modern film and...
I love how she describes the public-facing aspect of her work as "performative." I have always found speaking with people when under a darkcloth, letting them peek at the ground glass, answering...
My 8x10 Deardorff can handle a 75mm Biogon. Of course the lens won't cover the format, but I love the circle.

I have a 5 gallon still I found at a second-hand store years ago that works perfectly. I use distilled water for mixing developer, sensitizer, and toner. I use tap water for everything else. The...
Yes, this was my thought, someone stripped the paint.
Those are lovely. Really nicely done. The white background can be so unforgiving, but yours is wonderful and really helps the plants pop out.
I am curious, are those beveled edges on the plates?...
I picked mine up this afternoon!
Welcome! There is currently nothing formal as far as I know, but there are some networks centered around the Bluemoon Camera store, as Paul mentioned.

Yup, I had the same thing happen with my Lee hood and Barge worked as expected.
The heat absorbing glass is indeed 3mm, and comes mounted on a metal carrier, as you guessed...

What do you need to...
Thank you for posting! I have a 130mm f12 Rodenstock Weitwinkel Perigon, which to my knowledge is the same design as your Eikonar but coated and in shutter. In my experience it just illuminates 8x10...
Thank you!
I didn't find the curl to be an issue. It sat flat in my holders, and didn't shift around much. I think I have figured out how to cut it evenly (which is, apparently, what I do on...
I have also been playing with one of the 24cm rolls of Aviphot 200. I bought it with intention to use with 18x24cm, but ended up distracted by 7x11". I am currently using it at 100 iso developed in...
Both are certainly soft focus lenses, however the Varium is not as soft as the Verito (at similar apertures), and to my eye the Varium has less halation (so, less highlight glow). The Varium is also...
Michael, rather than scan can you set up a copy stand and just use a digital camera?
There is a free app (f-stop printing calculator) that works well enough, but is limited to 3/4, 1/2, and 1/4 stop
Before you spend a lot of time and money on this lens, consider if you need a lens this fast. Are you planning on using it at f3.5? If not, perhaps you can find another 240mm lens in better condition...
I went back to my notebook from when I purchased the lens (2009), and realize that I had it professionally polished. At the time Arax in Kyiv was doing good optical work very cheaply, and I sent the...
