How were barrel lenses used to make exposures on process cameras?

[Jim Andrada]

The process cameras I was familiar with had vacuum backs inside the darkroom and timed lights in the room where the front of the camera was.

Thanks again for all the information shared here!
I have a follow up question to this thread about APO Nikkor lenses:
Are they too large to mount on a Linhof-sized lens board? I'm looking at possibly using the APO-Nikkor 305mm/9 (available from a friend) on a Chamonix 4x5.

If, that is, you know the board's size.
