Well I don't have the money to experiment with a film camera so I was wondering what the differences are in these things:
I wanted to add a jittery effect like in Saving Private Ryan for a battle sequence but what would the difference be if I closed the shutter to 45 degrees at 24fps (which means that each frame is exposed 1/192 of a second right?,I might have done the math wrong.)to slowing the speed down to 12fps but closing the shutter to half of 45degrees which is 22.5 degrees?
Ill simplify it down here if it was to confusing up there?.
24fps with the shutter at 45 degrees= 1/192 of a second
12fps with the shutter at 22.5 degrees=1/192 of a second
What's the difference????
another question is, if i change the speed of the camera but leave it at the standard 180degrees shutter can I compensate the light exposure with the arperture of the lense??
sorry if this was too complicated.

fd2blk,
If memeory serves, the scene in privete ryan is slow mo, with hard edged movement right?
This would be done by shooting at high speed (not slow speed as you suggested), and closing down the shutter. Exactly what effects you getter with different speends and different shutters is a matter of expereimentation.
In terms of aperture, the rule is simple enough, if you half the light coming in, you need to open up the lens by one stop.
This means 25fps to 50fps is one stop difference, 25 to 100 fps is two stops etc.
Similarly with shutter angle, 180 degrees to 90 degrees is one stop diffence, 180 to 45 degrees is two stops.
Combined this would mean that a 50fps shot with a 90 degree shutter would be two stops difference from the normal 25fps / 180 degree set up.
