I thought Ed and other of our members who paint would find this interesting:
"The technique used to animate The Lost Town of Switez is particularly innovative and striking, combining traditional oil painting with 3D digital animation. To compose the shots, handmade paintings were digitized and then composited to create the illusion of depth. Overlaid with animation, each tableau springs vividly to life. Faithful to the film’s historical context, the rendering style is based on religious iconography and Polish Romantic painting. "
