Oil paint
Chartrand utilizes a traditional animation technique known as paint-on-glass animation. It is considered one of the most demanding animation techniques. Chartrand familiarized herself with this technique when directing "MacPherson" and since mastered. The process involves manipulating wet media on a glass sheet/sheets, that's often placed on a projector for lighting purposes, all under the lens of a camera recording. Oil paint is often used because it dries slowly which allows an artist to work on a project for longer periods of time. The effect of this technique is the illusion of images seamlessly merging from one scene into the next.
