This is an interesting mini lecture by Disney layout artist and art director Ken O'Connor on how to cheat perspective effectively.
Ken worked on many of the Disney classics and shorts for a period of over thirty years.
I had the chance to meet him on a couple of occasions when he gave talks at Disney Animation.
The man knew what he was talking about. He was extremely skilled and enjoyed problem solving when planning layouts for animation.
Born in Australia in 1908, Ken moved with his family to the US in 1930. He started at Disney in 1935 and before retiring in 1978 he taught at CalArts. He passed away in 1998. Ken was an artistic giant within the Disney organization.
