I've been waiting and hoping, but haven't seen anything about a landscape video being released. Landscapes are a huge part of concept and fine art, so I'm a little surprised nothing has been released that focuses on landscape painting. I would imagine that there would be a great demand for that type of video, and I've even noticed that other organizations that sell instructional videos don't sell any type of landscape painting videos.
I'm mostly talking digital with Painter or Photoshop. I know there are quite a few DVDs sold for traditional media.
