In regards to the great Wall-E debate, cinematography is simply the image on film no matter how it was created. It is the look, the use of light, framing, composition and camera move. It's not about the challenge of manipulating existing light to create an image. Remember, nearly every film gets a pass in the computer where colors and other details are digitally changed. (Pull out your Se7en DVD and learn.) What matters is the final image. Wall-E doesn't have an unfair advantage because it's digital. (Or else how come nobody's pushing for Kung Fu Panda.) Wall-E's look was created through the process of numerous artistic decision, and certainly merits consideration for the final product.
And I can't believe I'm the first one to mention The Fall.
