I don't make a living via photography, but I do receive income from taking pictures of escorts, and pets. (Strange how you find your niche!)

I've been using RawTherapee, on Linux, for the past few years. For my needs of marking images, doing post-processing, and mass-operations, it works perfectly.

I'm always reluctant to allow a tool to manage the layout/tagging of my images. So for that I have a strictly sorted hierarchy:

    ~/Images/
    ~/Images/2016
    ~/Images/2016/12/04-Hannah
    ~/Images/2016/12/12-Tiffany

Inside each "event"-folder I store:

    RAW/
    JPG/
    JPG/thumbs/
    Teasers/
    Teasers/thumbs/

Then I write out a meta-data file, ".meta", with detail such as:

    Location=Studio|MyPlace|Their Hotel|Whatever
    Contact-Details=+44...
    Tags=lingerie,nude,shillouette,monochrome
    ..

It works well, and allows me to find files years later via a simple `grep`.
