I pulled out some 140# rough press watercolor paper to paint a few of the skies from the recent photos. It might be better to paint from the sky itself, but I haven't done that yet. Next time we get some stormy skies, I could set up in the sun room and use the sky as my model...

April Skies No. 1 (so you know there will be a No. 2, right?)
I don't have rules like:
You should only paint from life.
You should never paint from a photograph.
You must go out in the field to paint plein air if you want to get good at painting landscapes.
(As Dr. Gregory House said, "Rules are just simple guidelines for people who are too stupid to think for themselves.")
