The biggest effect of changing Shutter Speed apart from exposure is motion blur rendering - so for shows/movies it'd often be for artistic reasons. Eg Saving Private Ryan beach landing scene, dream sequences, flashbacks.
But I've seen it used for exposure control in things like tabletop food advert shots where motion is minimal, and the DOP dislikes using filters and wants Depth of Field to stay the same.
Perhaps the language barrier made it sound like I was calling you an asshole. I was merely shocked that you lack an understanding of the basic fundamentals of photography. Rather than ask here piece by piece, I was suggesting that if you read a book, you would get a better grasp on how the basics all work together. If you don't have an understanding of shutter speed and exposure, nothing else is going to make sense.
EX: lets say I'm shooting at 24fps at 1/48th (STANDARD), but I want a 90degree shutter angle instead of 180. Is that possible, or am I being crazy?
Beause the shuttle ANGLE is how much of the 360degree shutter is OPEN or CLOSED. And the SPEED is how many times said shutter rotates per sec right? Surely they can be seperated? Or am I missing something clutch and looking like a total idiot?
Thanks in advance.
With an electronic shutter, Shutter Speed can theoretically be any time value from zero (albeit pretty useless as that's just black!) to a maximum length of the frame interval, and Shutter Angle can be any angle from zero to 360degrees.
However, FRAME Speed and Shutter Angle are indeed independent, so you can be at 24fps and in theory have any Shutter Speed from zero to 1/24th sec, or any Shutter Angle from zero to 360degrees.
As per your example, if you are shooting 24fps and want a 90 degrees shutter angle, then you dial in 90 degrees or switch to 1/96th sec, they are the same thing. No you cannot separate them.
