So it appears as if the strip goes into all 13/14 tanks so a bit more than straight dev stop and fix and wash. I suppose that there may be say 3 tanks associated with dev but even so the time in dev quite short. Washing time is very short also. From what I remember the time from flashes to pics was probably no more than 5 mins.

There appears to be no negative to positive printing as such. Is the paper a direct positive as in the equivalent of a paper transparency?Toner was mentioned. What did this do?

It raises a lot of questions. Anyone know exactly how these booths used to process the prints?

I am curious now
