What would I have to do, to shoot 35mm @ 2:35 aspect ratio, on a Arri Lite & Arri Studio camera?
Would it be as simple as changing the ground glass, or is it more complicated?

The rental house should be able to configure it for you, just ask for 3 perf super 35 with the 2.35:1 ground glass.

That being said, 3 perf s35 is boring... have you considered anamorphic or 2 perf?

Why is 3-perf 2.35 boring but 2-perf 2.35 isn't???

So as far as camera is concerned, I would only have to change the ground glass?
Then I could take 2:35 out of 4 perf 35mm, but it would be cheaper and make more sense to take it from 2 & 3 perf?
Which makes sense, because I read that with 2 Perf, you save nearly 25% of money & film in the end?

Shooting a 2-perf tall frame means that you shoot half as much film as with 4-perf. Yes, it's a great cost-saver if you can find a 2-perf camera to rent.

The 4-perf 35mm Full Aperture is 1.33 : 1, so the 2-perf 35mm Full Aperture is naturally 2.66 : 1. 3-perf is about 1.78 : 1. You can frame any of them for extracting a 2.40 frame but obviously you waste the most negative if using 4-perf... Unless you shoot with anamorphic lenses.

Okay, that really cleared up my confusion. I appreciate your time & wisdom good sir.
Thanks David...

Keep in mind that 2-perf also leaves zero margin for error in framing or (eeek!) a hair or dust bunny in the gate. 3-perf gives you a little more flexibility in post.
