A "great" cinematography moment for me comes in, sigh, "Spock's Brain
" (I think" where Kirk walks across the viewscreen.
It's great because the image on the view-screen is rear-projected onto it and I believe it's the only time in TOS we see a character walk in front of the screen with an image displayed
. (Usually we're shown the viewscreen with the image put in during post) This was likely a very complex shot for them to pull off in the mid-60s and it looks great.
Kirk and Spock scroll right in front of the main viewer displaying space at the tag of The Doomsday Machine in the previous season.
