I have a Zone VI compensating development timer which I use regularly
and happily. However, with the company now long gone, the "lifetime"
warranty is not of much good :) Moreover, it was an analog device
with essentially only 2 compensating curves.
I am lazier than you. Although I used to design analog circuits and
digital systems, I never got one of those Zone VI compensating timers.
Instead I just always develop B&W film at 75F. I picked 75F because if
my water supply is too cold, I can mix it with hot to get 75F. And the
cold water supply rarely goes over 75F, I have a Lawlor thermostatically
controlled water valve and use it for wash water in my Zone VI print
washer. If I am not making prints, I just run that water into the sink
where all the bottles may be. I also do the developing in a Jobo CPE2
machine that can hold 75F quite well. If it is really hot, I just drop a
frozen "ice" pack in the Jobo tank off-and-on as needed, keeping a eye
on the thermometer.
I do the same for B&W prints, but other than the developer, it does not
matter as much. I do not use ice for B&W prints.
I gave up on color printing because my color work is boring to the
viewers and to me. But I developed C-41 ane E-6 OK in the the Jobo
machine, and made Cibachrome prints for a while. 4x5 E6 transparencies
are very interesting; they make very nice (boring because of my artistic
limitations) 11x14 prints: nice and sharp.
