What kind of timing device you are using for developing films?


My wrist watch. I start pouring about 10 seconds before the second hand sweeps up to the top of the dial. I also write down the precise start time on a piece of paper and add in the development time to tell me when to stop. That way I do not become confused trying to remember when 10 minutes is up. I only have to worry about my tank inversion regime on a minute by minute basis.

I am surprised at the number of people who use clocks of some sort. On another forum the answer most participants gave was an app.
 
Timing device user depends on process and processor used:

1) Film developing (up to 4x5): None. Phototherm Sidekick manages time automatically as per program, auto heats chem and maintains constant temp throughout.
2) Paper Processing: (up to 11x14 color and B&W): None, Fuimoto CP32 manages time automatically as per program, auto heats chem and maintains constant temp throughout.
3) Jobo CPP2 Print Processing: Gralab 300
4) Enlarging: RH Designs Analyzer Pro (combo f-stop analyzer and integrated timer)

For Film development a Gralab 300 it dose throb for me, and for the enlargers a Time o Lite EZC 69 that works great.
 
For B&W film, hand agitated in steel tanks, I use a GE X-Ray clock timer I received used in 1958. For color films and papers, A Vivitar Process Time Commander, controlling a rotary drum processer from early 1980s.
 
Talking Timer - soothing electronic voice that counts down while I tray develop sheet film in the dark.
 
I use the iPhone Timer from Digital Truth (Massive Dev.).

I really enjoy it for hand agitation...my films have all been spot on...I like the little metronome
sounds and beeps...use it with PMK.
