Here’s a presentation about underwater photography with the Olympus/OM System TG-5 and editing the images with open source software packages darktable and digiKam.

The presentation was part of a face-off with another member of the South China Diving Club. He uses much more expensive equipment and commercial photo editing software.

The video covers equipment, software, workflow, technique and philosophy.

It may be of interest to scuba divers and snorkelers, and to anyone thinking of making the move from commercial to open source software.

Christopher Dillon chaired the Hong Kong–based South China Diving Club from 2018 to 2020.
