Welcome aboard @Brian_Innes! Linux photographer here as well from Ontario, Canada. Glad you found this place; I myself only found it not long ago and I’m very glad I did. You’ll find it’s interesting to find out about the most cutting edge feature developments they’re making, as well as testing. For example they just finished version 5 of RawTherapee.
I too prefer Hugin for panoramas and would love to see some of your work posted
