Keeping Time tray developing film

[Tin Can]

At home, I have music playing continuously, silence is deafening

Not muzak, as I have a fantastic community radio station, which I support with a few $

Also in DR and love darkness, so peaceful, I always feel great after a session

However when riding my bikes wind and birdsong is sufficient

I bought new cars without radios many times

I use a "Talking Stopwatch" app on my phone. You can tell it how often you want the app to tell you the time. I use it for my film agitations. I think everyone's phones go dark after 30 sec or so, depending how you set yours up.

A phone is another thing I go to the darkroom to avoid.

Audio can be downloaded and played in the smartphone.

That is the one I use too, it's nice, put yourscreen at the lowst brightness, and point it were the light cannot harm.

[Drew Wiley]

Indeed. Be careful where you aim or place anything even slightly illuminated. Light can always harm if film in the tray is in a position to "see" it. I just don't buy, "it's never happened to me" talk. That's like saying you've never gotten rabies, so there's no need to worry if a dog is foaming at the mouth or not. I learned that the hard way after the deep shadow values in some 4x5 early TMax mountain negs that were quite strenuous to acquire in the first place got fogged by luminous timer hands clear across the room. Never again.

No phones, computers or tablets in my DR

If I fall, I will either crawl to one or die happy

I use a DLG compensating timer (as I no longer have my old Zone VI compensating timer). It has a red LED display, but it's on a shelf where there is no line-of-site between the display and the development tanks. Yet, I still set the LED display on the dim setting, just because I like belts and suspenders.
