Hi all,
Darktable is a - free - Raw developer which I feel is underappreciated.
They added Fuji support about a year ago and I've never looked back since.
I was using Corel Aftershot (previously Bibble Pro) and darktable is a full-fledged replacement at an unbeatable price.
The learning curve might look steep but just watch a few youtube videos and it will all make sense very quickly.
