This is an article against DNG, I liked it because it clearly goes through what the pros are of DNG but then goes on to say why they still don't like it. They feel that it is weird to throw away the raw files, and while they understand why and are not purely against DNG, they still prefer not to use it.
What I suggest we watch if we do end up watching a movie. It is a Wes Anderson film so as expected it is visually beautiful in its camera work, and its his only animated work so not only is it beautiful but also animation, so it fits the class really well. We could always just watch Studio ghibli or something if no one likes this but thats just animation (beautiful animation) but no camera stuff
