When someone posts a painting and informs us that they have done the
painting from a public domain image is it appropriate to praise them on
the composition or elements of the image. I would think not.
It seems to me that in that case we should only be talking about the
quality of the painting. Technical drawing and painting stuff. Color,
Value and brush work.
It also seems to me that the photographer should get
attribution. Most of the 'free' stuff is on a creative commons license.
Usually part of the CC license is attribution.
Related to this. If someone posts a painting from another source and does
not attribute it or inform us that it is not their material how should
it be treated?
This is serious. We should not say that it's more
important to just keep painting.
How would you feel if your work was appropriated and published under
someone else's name?
