Consider TMAX400 (TMY) if you intend to do any alt-process printing that requires UV exposure. Because it has no UV-blocking your print exposures will be much shorter than with other films. Yes,...

Not all 210mm f/9 Graphic Kowa cells will fit a Copal 1. I have a recollection that some versions don't allow removal of one of the cells (rear, I think, but I'm not sure). And I could be wrong. ...

What Michael said - they need to be quite thin or you'll get ugly results. I don't often use this technique, but it has occasionally been useful.

I use 4x5 Ilford Ortho Plus film for my 4x5...

Welcome.

B&H sells Cescolite 10x12 trays: https://www.bhphotovideo.com/c/product/13148-REG/Cescolite_CL1012T_Heavy_Weight_Plastic_Developing_Tray.html

I bought a couple some time ago for...

Got it. Still looking for the Grandagon-N 200mm. That's the only one I don't have.

Noted, thank you, and thanks to those others who've helped me in my lunacy. It has been pointed out to me that Schneider called them "Makro" while Rodenstock used "Macro". Unfortunately that came...

I've been compiling a list of the part numbers of the aperture bands of Rodenstock large-format lenses in Copal shutters. There's no reason, really, it was just something I started doing out of...

This is a little off-topic from HABS & HAER, but might be helpful to someone out there.

The Staedler Pigment Liners work great on LF and 120 film, but I've found that the ink doesn't adhere well...

If you'd give some indication of your locale you might be able to find someone local who owns a shutter speed tester, like a Calumet or a Phochron XA. There are other, more professional, units out...

That's a beautiful book. Do you know if there are any plans to distribute it in hard copy?

Per an email I received today, University Products is offering free continental-US shipping this week (27-31 October 2020) on mat board. They offer two product types under their Lineco brand -...

I have a 400mm f/8 Osaka (same as Congo, just a store brand for Bromwell Camera). Optically it is slightly worse than a 400mm Fujinon-T when viewing 11x14 enlargements with a loupe, but it's also...

Celors are listed in the 1913 and 1915 Goerz American Optical Company catalogs on the cameraeccentric.com site. It's a double-anastigmat claimed to cover 10x12 wide open or 12x15 at f/16. The list...

Maris, it seems you have a lot of info on these lenses that isn't available anywhere else. Is there any chance you can scan it all and somehow make it available for posterity?

A few years ago I got a made-to-order Nagaoka 5x7 with the help of a Japanese colleague. It's the "Woody" model, not the one on the cover of the brochure Randy linked. At the time Nagaoka-san said...

The 300mm Fujinon-T is not exactly a lightweight - the one I used to own weighed 484gm (compared to 632gm for the 400mm Fujinon-T and 285gm for the holy grail 450mm Fujinon-C). I sold it because a...

Thank you, Ken, that's an important point I'd missed when re-reading both threads.

Seeing this thread come back to life prompted me to go back and re-read Sandy's original article. He mentioned he used this method for scanning. Have any of you recent posters (Ken, Larry, and less...

Other sources are University Products in MA (their in-house brand is Lineco) and Frame Destination in Texas. I've mostly used Lineco lately but have to take care that inclusions are invisible in the...

And if you do follow Jason's advice, please post your testing results so others can learn from you.

Dan Daniel in Burlington, Vermont. I'm not sure if he works on Compounds, you'll have to ask him.

I think that hole at the bottom is more practical than serving Fred Picker's hallucinations. It allows the water to drain when you're done using the washer, no need to tip it out.

I sure wish I...

I think the Gigapixel lens also used a thick glass plate. My guess is it's to do with color correction. Perhaps Nodda Duma will chime in here, he's a professional lens designer when he's not making...

FWIW, McMaster-Carr sell JIS threading taps in addition to standard 3mm x 0.5mm metric taps. No 5-48 taps that I could find, though.

If you read back to post #26 you'll find the necessary information there.

Remember to enter the tracking info into eBay/PayPal after you've shipped.

One of the great problems with the Internet is the diffuse and repetitive nature of information. There seem to multiple Facebook groups on almost any topic you can imagine, photo-related or not. I...

Isopropanol (a.k.a. isopropyl alcohol) dissolves some inks including Sharpie and won't hurt the plastic. I'd try it before resorting to acetone or nail polish remover.

As Schaf said, the Micron and Staedtler pigment liner pens work well for me on both 120 and LF film.

A word of caution to those of you who might, in a moment of weakness, use a 35mm(!) camera - in...

Not long ago I found a filter that prints with even higher contrast than an Ilford #5 or a Rosco 68 - the Rosco 384. The #5 and R68 print with near-identical contrast with my Aristo V54-equipped...

This lovely old door may well have been destroyed in the 2016 Soberanes fire.

This is what you want. It's Post-It note adhesive on a roll of tape. The box I bought said Removable Magic Tape. It comes in several widths, I bought both 1/2" and 3/4" at Dick Blick.

Nice solution.

Do you have any issues with negative sag using a glassless 4x5 carrier?

What technique(s) allowed you to remove it?

Since you say this book is hard to find, could you summarize the "Sheet Film Attenuator"? Is it a home-made step wedge, or something more?

I believe this may be a Rodenstock Ysarex, but I don't remember where this bit of mental lint came from. The Vade-Mecum doesn't mention LF Ysarex lenses, but the Rodenstock GmbH Wikipedia page lists...

I had the opportunity to weigh one a while back - 975 grams including the caps and retaining ring.

And just to make it more confusing, sometimes the 3S-sized shutters are marked as 3, or even just "Copal". You really need to measure them.

A later 355mm G-Claron should be a direct fit to a...

Interesting. I'll have to see if they have something similar for where I'll be in CA, though I'll have to find a station number first. Alternately, I can just use the Maine info and figure out the...
