This morning I attended a demo by David Leffel as part of the Weedend With The Masters, sponsored by American Artist Magazine, at the Colorado Springs Fine Arts Center. David has so much knowledge and so many years experience of painting and sharing that it's amazing. I have read the book "Oil Painting Secrets From A Master" by Linda Cateura but listening to him speak and watching him do even a short demo was wonderful. As the workshop title says, he truly is a master.
Some of his points were:
-everyone paints the way they do because of the way they think. if you want to get better, change the way you think.
-"essentially, I paint light and shadow"
-a painting always has movement, irregardless of the subject matter
-it is better to be definately wrong, than tentatively right
-Edges: an open edge continues, a hard edge stops. Alternate your edges: hard, soft, hard, soft.
Of course, there was so much more.
