Part III - Build The Ultimate Darkroom Timer - 3D Print

The goal of the darkroom timer build is to make it without much fuss, it’s inexpensive and accessible to anyone with basic knowledge.

In part three there's a lot of firsts for me. Let me explain, first I used Fiverr for the 3D design. This article is not sponsored I paid everything with my own money. Secondly I used AI to optimised the code just for fun by the way it's complete crap at writing articles regarding darkroom in fact it's quite funny however it mixes thing up.

If you haven't already read part one, please do check it out, then things maybe a bit more clearer.    • Part I  - Build a F-STOP Darkroom Timer

6:38 3D Print assembly
9:07 Final thoughts

Darkroom timer are simple but don’t work the way they should. At least time based ones they are linear. Photography isn’t linear. F-Stops are logarithmic, i.e twice the light or half the light through the lens aperture. The enlarger is essential a camera in reserve. This easy to build darkroom timer will not only show exposure in time but it also display in F-Stops.

F- stop printing was originally made popular by the award winning printer Gene Nocon in 1987. If you want the full explanation, you can find it in his book Photographic Printing (now out of print, but available on the second hand market), or you could take a look at this interview with him.
