I stumbled across DarkTable due to a discussion about GIMP and Photoshop on Google+. I didn't know about this program and was happy to see it in the repo.
I installed and it looks pretty neat.
It might make for a good "how to" article in PCLinuxOS magazine.
Are you suggesting that you would like to see an article about it?
I am sure it would be interesting.
If on the other hand you were wondering if the magazine staff would be interested in an article that you
write about it, I can tell you, they would probably be very interested.
It doesn't even have to be a "good" article. They will make it look good.
