cedar rapids art museum We all remember traditional animation, which has been carried out with hand drawn art. A group of animators illustrated and colored the pictures on celluloid. The celluloid was transparent sheets, the place that the hand drawings were transferred. Each of these "cells", since they were called, were then photographed individually which has a super 8 or Oxford camera. Whew ! Lots of work? Well after a while, technology has allowed animators to use CGI or Computer Generated Imagery to exchange the "painful" frustrating work of the past.
