Darkplug

Darkplug is a darkroom timer for iPhone and iPad that controls an enlarger through a Shelly smart plug on your local network. Time straight prints with an optional count-in, and with the one-time Darkplug+ unlock work in f-stops, run guided test strips, plan dodge and burn steps on a grid, split grade with two channels, and time paper development. The red-on-black interface was tested not to fog paper. No subscriptions. Built by Péter Szentkirályi, a film photographer.
