How do you keep track of time when tray-develop?

Ole, could I use the Debussy orchestration of two of the Gymnopedies for N-1?

Whatever works. Even Mahler's 8th symphony for stand development

The recorded tape/CD is a cool idea. I need to try that.

Heres an idea which I have had no experience with but have thought about it for a while. On the film makers developing instructions it always mentions something like subtract 15% time for drum agitation. Could you not use continous agitation in the tray and subtract 15% of developement time, then all you have to do is time the length of developement and not worry about the intermitent agitation thing. Just a thought.

I use a metronome, a cadance counter used in music, set at 60 bpm.

Hi,

I wonder how you keep track of time when you tray-develop your negative.

When I develop MF and 35-film (in a jobo) I have made a program that runs on my phone (java-application) which plays a sound every 30 seconds (to know when to agitate) and I can see the remaining time in the display.

However in a darkroom it isn't that safe because a phone call during my develop will light up the display, so therefor I can't use that program and now I wonder how you do it.

I use a Gralab 900 process timer. Prior to my aquisition of the Gralab I used a Heathkit darkroom process timer for over 20 years. Both have the capability of programing sequential steps of varying times which will start automatically or by the press of a footswitch. An audible alarm can be set in varying modes and the display can be dimed or turned off.

But don't turn it up too loud, or you won't have stand development any more.
