Wow! Just great stuff. Largest "camera" I saw was such a thing for reducing integrated circuits masks in the old DDR.

Everything was imperial in those days

I bet my old employer still uses a 4X4 ft process camera.

They make automotive gaskets in 1 million sq ft, Skokie IL.

I got a tour decades ago, camera had a very heavy hinged vacuum back in the wet side room.

The lens and LONG bellows in another room, with adjustable boom lighting.

They silkscreen their boxes and many gaskets.

First make holes with repeating presses, then silk screen repeaters RTV around the holes

Millions for IC engines.

Electric cars are their biggest worry.

Fuck em

When they went out of business my father rescued it and put it to work. We used it for both copying large artwork and for producing 60 x 40 positives for screenprint.

The cold cathode back was probably for copying transparencies, though it would work in a limited fashion as an enlarger.
