I know this is normally a Friday thing, but my weeks are so screwed
around right now that it may as well be Friday.
Anyway, I found, while digging through my crates of junk that I am
trying to winnow out, a piece of equipment that would be of interest to
anyone still running a darkroom.
The article is a Zone VI Compensating enlarger timer, complete with
photocell.
This is pretty much the cat's ass of darkroom timers, especially if you
are using a coldlight (more on that in a moment)
The photocell will, when mounted into the lightbox, adjust the time to
compensate for variations in light intensity. It also has a drydown
compensation of up to 15% to take into account the fact that photographs
look brighter in the fixer tray than they will when dry.
This isn't my timer, but it looks the same:

The more in a moment part: I also found an Aristo cold light head with
an adapter ring to fit the Beseler 4x5. The head is prepped to take the
photocell.
IIRC, it needed about a 40 yellow filter to bring the light to a grade 2
when using Ilford multigrade paper. I no longer have that filter, but
one shouldn't be too difficult to obtain.
The timers seem to go for about US$150.00 on eBay. I will let the timer
and head go for Can$150.00, buyer pays shipping.
thanks
bill
