I remember I had posted few resources on the Albert Withlock back in last year. I just came across these videos about the craft another great master matte painter Peter Ellenshaw. Thanks to one of the member called Thomas on mattepaiting.org for posting these highly valuable videos.
It is amazing to see that how matte painting techniques overlapped so much with overall compositing process of the film. It never stop to amazes me that basic fundamentals of the craft always remains the same while just the tools and techniques advances.
Somehow I also stumbled on a really great blog by Peter Cook with quite lot of articles on classic matte painting. This is a must bookmark for people who are fan of all classic matte painting masters.
I had mentioned about some great resources hosted by vfx artist, Domingo Lizcano in my last post but now I saw his blog which also have few interesting and informative articles on class matte painting.
