I would like to see these images!
I've received the ring from Rafcamera, put it on the rear cell and adjust to 110mm overall length.
Now the image on the GG is sharp (it was very soft before and overall length was 102,5mm)....
You can eliminate back side emulsion
Less density (more exposure needed) but more sharpness.
Kodak T-mat G/RA 18x24cm expired 2017 and cutted down to 4x5. Exposed at 100 ASA. Developed with Rodinal 1+100 semi-stand for 45 minutes. Symmar-S 210mm. Castanea sativa in Sotoparada - León (Spain)...
Thank you. I will look for this holders.
Hello.
I have a Meopta Magnola (13x18 field camera) but I don't have film holders to use in it.
Does anyone know if they can be found, built at home or change the camera back to accept standard...

Locking system approach. Springs made from brass sheet.

Today I've done this...
Saw, razor blades, Cork, glue, autoadhesive dark felt.
Pending is the locking system. By now I'd use rubber bands....
Mine is Micro Technical Mark VIII.
I have 3 original boards but the most lenses are mounted in homemade boards. I make them from dm with glued natural calibrated cork rails.
I am planning to build an adapter to use my mpp board mounted lenses on different cameras.
Show yours, your ideas, doubts, materials, success, fails...
Very interesting.
Your shutter is some kind of hybrid. Mine is labeled as Copal 3 but threads are 56x0.75 (3s).
Edit.
Can you help me measuring f-stop numbers in this copal 3. I would need...
Thanks Daniel.
I've written a WTB announce in the forum some days ago but it seems something not easy at all.
My most used camera (MPP Mark viii) has some problems when mounting copal 3 (I need to...
I have tested (loupe on the gg) the lens against other mounted on Compound iii. My lens is totally soft on the copal 3 but when mounted on this compound it turns sharp as the other lens. It seems...
You're right. I found in this book that "3" is the name that Mr. W. Voigt give to Compur Electronic 3. So it refers to the availability of the lens in both compound iii and compur electronic 3.

Friedrich W. Voigt: Schneider- Objektive fur Foto, Film und Fernsehen, Seebruck 1971.
it's okay. I will ask in a different way. What is the difference between these pairs?

I have found a table that says Compound III / 7 + 3.
What does that "+ 3" mean?

I rarely use color negative but lots of chromes. Neither on 4x5. I use Fuji and kodak chromes on 35mm, 645, 66 and 67. I love them
Price is my principal "con".

Thanks to all for your replies. I`ve read and appreciate all of them.
You have the key. I`ve tried to unscrew both cells and only get max. 106.2mm of total length. I don`t have a Compound...
Thanks for you reply.
So your h1 (overall length) is 108 (aprox). Mine is 102.5mm and a friend's copy is 109.6mm.
How about h2 (shitter seat to lens rear). Mine is 22.3mm. My friend has...

Hello
I've just bought one of these lenses. Serial number tell it is from 1954.
Shutter is copal 3 but it isn't its original shutter (max aperture is 4.5 instead of 5.5. See pic #1. I guess...
Thank you both for your replies.
I forgot to mention that I'm going to use the lens on 4X5. That means I'll only use the central part of the coverage. Considering that RR are used as normal lenses...
Hello.
How would a Rapid Rectilinear design compare to this Cooke Triplet?
I'm planning to build a very simple compact long focus RR. I don't have lenses longer than 300mm. I'm wondering how...
Another point: focus shift while stop down happens with convertible lenses when using converted. So seems to be related with alterations in the iris position or configuration. This barely occur with...
I'm going to buy some X-ray film (kodak t-mat G) and the lot includes a processor. I have no idea how they work and if I can use it for X-ray or conventional photo film. The processor is like this: ...
This has amazed me.
I would like to know what model is her vertical washer and how it is been used.
If you want to compose the exact picture on the ground glass and never ever crop the negative, the use of close up lenses may be interesting.
You can carry three lenses and 1 or 2 good achromatic...
You can use filters below the lens. I don't see benefit at all.
Good point. A carefully located thin layer of transparent kitchen film could work.

Maybe animal specimens in formaldehyde... Sorry my curiosity [emoji12]

I was thinking in coating after processing, not before. So would be necessary to develop the film with extreme care. When dry I would spray one or both layers. This could help to handle the negatives...
Hello to everyone from Spain and Happy covid-free new year.
I've never posted but reading the forum for long time, this thread for more than a year.
Finally I was gifted some X-ray film: Fuji Super...
