Just curious if anyone could shed some light here, I stick to the general rule of thumb when shooting 24p 1/48 or 1/50 depending on the camera.
What would you want to achieve by shooting a higher shutter speed? Obviously I see the benefit of lowering it for a better low light performance, but what is the benefit of increasing it?
Does it change the look of the film much from the "true" 24frame film look?
I guess I could pull out the camera and try for myself, but may as well get some opinions here while I'm stuck in class.

Watch the Normandy beach scene in Saving Private Ryan. That says it all.

The effect is stuttery and crisp, which works well for intense, hectic action. But it's definitely a special effect. Shoot 1/50 or 1/60 (under US lights) for a more normal look. 1/30 can look mushy but can be useful in low light on a tripod when there is little motion in the scene.
