The four topics were intended to get the membership ready for plein air work:
- the sky and clouds
- verticals (trees and hills)
- the land
The verticals demo was done by Lisa Sheppard. I very much enjoyed watching how she built her value masses, based on the angle from which each mass was lit. And then she brought them to life with just a few additional strokes.
The land demo was done by Mary Anne Warner, a 'realist' painter of large skill, who (unfortunately for her, here in this locale) hates green!
The water demo was seriously instructional, based upon the correct premise that the more you know about a thing, the better you'll paint it. It was presented by Deborah Maklowski. (Another excellent How-To-Paint-Water in pastels demo is here.)
Two books were mentioned reverently by more than one presenter:
--- Carlson's Guide to Landscape Painting, by John Carlson (1958)
--- Capturing Light & Color With Pastel, by Doug Dawson (1991)
From what I saw, the Carlson book looks pretty interesting. We'll see. It's on the way!
ADDENDUM: On the way home I discovered an outstanding little grocery market in Olney (west side of Georgia Avenue): Roots Market. Great spot! Really good stuff. Decent prices. A little Dean+Deluca and a little Whole Foods. I intend to go back often. Wish there was one closer!
