Very large format "camera".

This might be of interest. It includes a demonstration of developing by rolling.
I'm surprised by the short exposure time. He has other ULF projects too.
Don't be put off by its being in a digital forum.

Photographer Brendan Barry creates a giant camera obscura using a customs house

Brendan Barry has a lot of experience with creating analog cameras in interesting places, including a project earlier this year in which he turned a shed into a camera. Barry was recently commissioned to create a camera obscura using a room at the Custom House in Exeter, U.K.

Interesting David, did you see the giant one made in an aircraft hangar (different photographer) where they used loquid emulsion.

Yes, I've seen it. I was very impressed by the amount of work needed to lightproof the hanger and then coat and process the canvas.
I believe it still holds the official Guinness record for largest photograph ever and it would be a hot contender for Most Boring Photograph, too.
I think Brendan has done much better, except for sheer size.

I'd agree the quality of Brendan's images seems much higher and more prctical.
