I taken many of Johannes' painting classes on the computer and he gives a lot of great info for landscape painting. He has a new course starting Saturdays Jan. 25 through Feb 8. It is 4 hours each session at a total cost of $18.99. If you miss a Saturday, a recording will be available free of extra charge.
He is really worth watching. The first session will be in oils and the two others in watercolor and pastels. Here is the link:http://improvemypaintings.com/
Scroll down through the explanation. There is a "register now" button near the bottom.
Important note: After you make your payment you will have to register a second time at "go to meeting" or you will not have access to the live video. Check your Northlight receipt for the registration link. PayPal payees send a copy of your receipt to this email: email@example.com
