street art graffiti We all remember traditional animation, that was carried out with hand drawn art. A group of animators illustrated and colored the photos on celluloid. The celluloid was transparent sheets, the location where the hand drawings were transferred. Each of these "cells", as they were called, were then photographed individually using a super 8 or Oxford camera. Whew ! Lots of work? Well eventually, technology has allowed animators to make use of CGI or Computer Generated Imagery to change the "painful" frustrating work of the past.
