The use of f/stop timers gets mentioned a lot on various photo forums and having read "Photographic Printing" by Gene Nocon, it seems to be a very logical way to produce enlargements.
I have an enlarger timer that allows me to control the exposure time in 0.1 second increments, but I have never actually used a dedicated f/stop timer and I am very tempted to buy one.
There is a chart in the book for using a regular timer for f/stop printing, but surely an f/stop timer is a better option? Does anyone regularly use an f/stop timer and do you feel that your time and effort in the darkroom has improved compared with using traditional timers?
