Thanks for the information, Oren. Sounds like an interesting experiment but generally not a viable technique. No matter how convoluted the apparatus, you can’t add data that’s not in the original. ...

Hi, Oren
Did the setup appear to be basically a camera oscura? If so, that would suggest the appearance of good DOF and hence apparent detail in the equivalent of a contact print. Was that your...
An Omega E-5 with a cold light head works well for BW but are very difficult to find anymore. However, they're big enough that shipping by USPS, FedEx, etc would be a major problem compared to...
Look for one of the BW King inversion 5x7 tanks on the web. These are basically like a jumbo 120 reel and stainless steel tank, holding 6 sheets per reel/tank for each development cycle. They work...
Some barrel-mount G-Clarons, earlier Schneider Repro-Clarons, and Computar process lenses were apparently designed to screw directly into various Compur/Copal standard shutters without the need for...
The Rittreck with 5x7 back weighs slightly less than 4.3 KG, heavy but solid and well-made. It is a good 5x7 folding field camera - I have two - but not a camera for long hikes after taking into...
Hi, Drew
Thanks for the kind note. I have read your posts, as well as the back and forth with many others, with interest and appreciation.
Yes, I've heard that about Moonrise and some other...
I'll bet that the wide variance that you saw on your grey cards is also true of many, many light meters, both handheld and in-camera. I've found that my several light meters are not really...
I wonder if Amazon will ship naphtha. Ronsonal might be the easier way to go. Even easier, send the shutter to Carol at Flutot camera repair for a proper overhaul and CLA
Thank you for the information. I will try it sometime if I ever run across a 75 SWD. I like my little 75 /8 SW on 4x5.
Not recent listings - I bought these 135 W lenses over time a few years ago. I have the 75/8 SW for 4x5 and it covers well. I never considered using a 75SWD on 5x7 as I found the 90/5.6 SWD to be...
I did not see perceptible sample variation on the 3 Fujinon 135 W lenses. I have some other sets of Fujinon NW lenses, 125/5.6 and 150/5.6 and I did not notice evident sample variation in those...
I ended up buying from Japan multiple copies of the original Fujinon 135 W with inside-writing.
One is mounted on, and calibrated to, a 4x5 press camera. The other two are used as compact...
The Fujinon 105/8 NSW might fit the optical requirements on 5x7 as it has an image circle of 250 mm and hence quite adequate coverage. Both of my copies are very sharp and contrasty on 5x7. These...
I bought one BW King for 5x7 and 4x5, liked it a lot, and bought a second. They work very well, at least for me. The two that I have are both well-made and workable, especially when used as...
I looked at the Art Journal article and, as described there, the physics are purported to be basically a dual camera obscura with the second such aperture apparently receiving only the center of the...
I was attempting, apparently unsuccessfully, to avoid dissing the author while suggesting that other materials might be more useful in troubleshooting the OP's problems.
Usably large exhibit-grade contact prints
I've found that a good weather-resistant M 4/3 camera and zoom combo like the Olympus E-M1 II and Olympus 12-40 Pro zoom is a very good foul weather complement to my LF and ULF gear, particularly...

I took a weekend workshop with Mr. Horenstein some years ago and he told the rather humorous story about how his book evolved very quickly, so I'm not surprised to hear that you are having...
For a full generalized explanation, check out “Airy Disk” on Wikipedia.
Why not just get a used Calumet shutter speed tester off the bay? Reliable, simple, not very expensive, and no fuss.
Ai has been evolving since the first rules-based "expert" systems of the late 1960s and early 1970s, which evolved out of the original DARPA Project MAC and Marvin Minsky/Seymour Papert at MIT when I...
Does anyone here have any actual experience / thoughts about the usefulness of a 7” / 183mm B+L Protar Series V wide angle coverage on 11x14 used only for contact prints ?
12inch Dagor covers 11x14, at least mine does. Of course, there are many flavors of Dagors.
Hi, Mark
What are you doing now in North Wales, asks this MIT type in rural Alaska <GG>
Slightly less than 41 KG
Yes, indeed. Such as Karsh and his Kodak Commercial Ektars, a Tessar-pattern lens.
Actually, this might be both redundant and recursive as AI generation systems are generally tested and refined by challenging them with a different AI system that tries to pick holes in the first AI...
Hass units are top-notch, but buy at least the intermediate grade unit and install with lots of small particle filtration. These solved my processing water quality issues and the build quality and...
I've got a Toho that I bought from a retiring commercial photographer in CT. He apparently used it for studio product photography for years and it was still in excellent condition when I got it. ...
Although Brian's observation is, by and large, legally accurate as a general evidentiary matter, AI complicates legal matters in a manner that we don't entirely yet understand and that will likely...
That's not the case - intentional or reckless misrepresentation is clearly unethical and punishable in virtually all US jurisdictions.
In my 46 years of law practice, admittedly in Alaska which...
The Canham MQC57 is apparently discontinued and no longer available new.
Yes, the Canhams are very very good and light for what you get, including longer bellows. However, unlike the Technika, there's not a rangefinder option for handheld use.
I have a new Canham...
What about mixing with distilled water? No iron or other metals in distilled water and hence nothing to chelate.
I’ve been using the 5x7 BW King 6-sheet stainless reels and tanks out of China. These will work with both 4x5 and 5x7 sheets when loaded using the 5 “ edge. These handle just like big 120 SS reels...
I experienced a septic system failure about 15 years ago that I attributed to photo chemicals down the drain and killing the digestive bacteria over a period of years. Even though I dosed the system...
There's always Alaska. None of the NP here are crowded.
