@Ivan_Kuckir :
I saw the PhotoPea announcement on dpreview.com.
I checked some of their Twitter posts and found this: https://twitter.com/photopeacom/status/1430988598929764355
The images looked familiar… and yes, they are from darktable: Color Mapping | darktable
All the stuff on the blog is CC or GPL licensed.
So minus points for lack of originality.
But doesn’t that CC licence require attribution? (Don’t know if PhotoPea is commercial)
They did add their own copyright message “10:20 PM · Aug 26, 2021·Hootsuite Inc.”
They are free (as in beer), ad-supported with an optional subscription.
That’s not a copyright message, it’s a time stamp and the client the message was posted from.
