Maintain exposure and development consistency with this clip on metronome.
In collodion work, it's important to maintain consistency in both exposure, and development times. Timers are great, I've used one for years, but when your hands are full, it's hard to get to the start/stop button in time or keep water from wet gloves from seeping into the buttons and guming up the works.
Instead: ditch the timer and free up your hands with this handy clip on metronome. It's simple to set up and operate and can produce an audible beep every second. Both beep frequency and volume are adjustable. And if you really want to spice things up, so are the rythms! It even incudes a phone jack if you'd prefer using ear buds.
I've been using this for some time now and find it much easier to manage than a hand held timer. Try it out, you might like it too!
