My first post. Thanks very much to everyone here for the great information. I have been using Darktable for a couple of years, migrated here after leaving Adobe Lightroom. I very much like the program and am learning every day. Running Darktable 3.6.0-1 under Manjaro Linux on a dual monitor setup.
I have cause in my work to share some of it online for the first time. In reading elsewhere, someone suggested adding a transparent foreground layer to a photo to present only the blank layer to someone who is attempting to download it. Prior to this I did a forum search to try to discover how this might be done in Darktable and did not find anything. Can someone point me to a thread where this is explained?
Many kind thanks for the great forum.
