I'm a Lightroom user since 1.0, but I don't have a Mac anymore, and using it in Windows VM is a pain. Over the years I've developed my specific workflow for reviewing images (multi-pass, rate 0/1, filter >1, rate 1/2, filter >2, repeat) that allows me to cull pictures extremely efficiently. My usage of Lightroom is mostly just applying film emulations, reviewing, and exporting in specific size. For that I developed opensource tool mini-film that covers all those aspects. It allows also multiple people to work at the same time on the same pictures using Web GUI, but CLI is also first-class citizen. Feel free to explore and leave any improvements ideas. Unfortunately I cannot share full set of example emulations, as the company behind the profiles is not too happy about that.
