Want to Buy WTB: F-stop timer for enlarger

TheToadMen · Nov 29, 2014

I want to try the F-stop printing method. This means I'll need a F-stop timer for my enlarger. So I'm looking for a 2nd hand "StopClock Professional F-stop timer" (made by RH Designs) or a "Darkroom Automation f-Stop Timer" (made by Darkroom Automation) for a fair price. If someone has one lying please contact me.

These timers are both great but remember that a simple electronic timer and an f/stop table can easily get you started

What Ralph says is right. It's not the timer, its understanding the principal that's important. There are plenty of charts available on the internet that you can use. Or, if you have a typical Gralab model 300 darkroom timer, you can make a circular chart to tape to the face of your timer that gives you all you need.

If you can solder, follow the link in my signature. All up cost is about $100 to build one.

Have a look at "secondhand darkroom supplies" shop in the UK. I bought mine RH Designs from them - a previous generation - for a very nice price and it works like a charm! After some time with an F-Stop table and a beeping metronome it's quite a bliss

Thanks for all the good advice and help. I will keep an eye out for a 2nd hand "real" f-stop timer from RHD or DA.
But in the mean time I'll do (=test) with a chart and my regular timer.
And read all the recommended & good documents about F-stop printing.
