Within the various technical departments, there are also a number of people whose jobs are more creative/less-technical but still involve a small (and varying) bit of technical ability. For example, matte painters, set dressers, shading technical directors (called surfacing at some studios), lighters, and camera & staging (layout) artists.
Animation is also more of a creative department than a technical one, but there are some basic technical skills animators need to know, as 3D animation's a bit more technical than just drawing frame to frame!
There are also non-direct-production creative jobs such as in the marketing department.
