My favorite photo development program remains lightzone, I find it has by far the most intuitive work flow that let's you achieve extremely advanced steps in a quite straight forward way (much of the functionality can be achieved in darktable but it's often very unclear how). I originally bought a copy but it has since been open sourced. Unfortunately it's photo management features are really subpar and development has been quite slow.

I wish I could use it just for the development and use something else for the management, but last time I tried that wasn't really possible. I have looked into contributing several times, but it's written in java and I really don't the have time to invest in getting up to speed first.
