F-Stop Printing in the Darkroom — Full Workflow + Custom ΔStop 100 Timer

In this video I walk through my full f-stop printing workflow—from the very first ½-stop test strip, to refining exposure in ⅛-stop steps, and finally shaping the image with dodging and burning in stops instead of seconds.

I also demonstrate a project I’ve been building: a modern enlarger timer designed specifically for f-stop printing, created to make darkroom exposure more predictable, repeatable, and intuitive.

Whether you’re new to the darkroom or returning to film after years away, this approach can make printing feel far more like craft than chance.
