As with sound, images are subjective. You and I may not see the same color red as red, but we will probably agree that the image on the screen is a digital image or film image, based on contrast, bit depth, and refresh rate.
I like engineering, but I love the creative input.
If you can imagine it, we can make it.
George Lucas wanted this moving camera for all of the photography in Star Wars. He was willing to take a risk with the concepts that I advanced with regard to ways for doing that.
It's an embarrassment of riches because you have directors who don't better. You end up with so much stuff going on the screen that you don't know where to look, and that's what I consider self-indulgent.
