I've been building a ULF camera. The plate size is 48"x48" The lens is an old military Dalmeyer 1328mm
I've still got to finesse the holder and dark slide and add a some focus rail locks.
I made the ground glass from frosted perspex, this will eventually be changed to glass

Wow amazing work and camera, what sensitive surface do you plan to use with it?
Collodion? Photo paper? Homemade gelatin silver glass plate?

Are you sure you can get it out of the room once it is complete? :)
That is quite a project - looks very good.
I plan to use both wetplate and also photographic paperQuote:

Amazing mammoth camera. Well done. I would imagine it Would be quite tough to handle this alone even for loading the film holder.

Can you "rig" together a plate holder from glued up bits of old Lisco holders? I am thinking, maybe only one sided with a backing piece toehold it all together and ensure rigidity and flatness.

Wow!! ULF indeed !! Looks clean and sturdy. I like it.
Can you extend the bellows out to 1:1 lifesize magnification?
As a side note, I have a hard time seeing the 48”x48” size, in relationship to your table and chairs. Is that 48” square or measured diagonally?
Wow, that reminds me of a graphic arts copy camera, minus the vacuum back. I'm sure it weighs less, and the one I'm most familiar is built into a darkroom on the film holder side. I've been told I can have it for free if I can move it without destroying the building. I'm not sure I'm up to that project yet. I need to go back and visit the print shop though. They still have a lot of the supplies and I could do some still life work with it at huge sizes.
I’ve made a plate holder, it would work for tin and glass, not paper.Quote:

I can extend 1 to 1. It’s 48” square
48" size is not a joke :)Quote:

That's quite clever. I like it!Quote:

The old solution - which still works on my over 100 year ULF cameras - is velvet ribbons. Any colour will do and it is commercially available in different widths. These were glued into a slight indent in the wood - about 0.5mm. Foam is a short term solution and felt is a poorer, dusty material and doesn't compress much.
Hullo Steven,
when I mentioned felt I wanted to mean fabrics in general as velvet - but you know the velocity of answering..
