I recently finished making this brief logo animation on spec for Staff of Life Natural Foods Market. This was a great learning exercise to help me hone my skills in After Effects. I started with their original, static logo art, and used that as a basis to create the expanded scene in Illustrator, then brought that into After Effects and used its 3D capabilities to animate the long camera zoom. (The birds are stock footage that I composited into the scene.) I also wrote the musical tag, and recorded that in Apple Logic.
