Trade-offs with shutter adjustment

Chad Perkins: Shutter speed is another way to adjust exposure but I almost never fiddle …with it. I usually keep it set at 1/50th of a second, because I usually shoot 24 frames …per second. Sometimes if I shoot 30 frames per second I'll go up to 1/60th, and if I'm going …to do slow motion, 60 frames per second, I would do 1/120th of a second, but these cameras …typically only go to 1/125th of a second, so I leave it set there. …And the reason why I don't adjust the shutter speed that much is because of how it affects the motion blur.…

Brian Liepe: Right, so motion blur is the streaking or smearing of quickly moving objects …in a photograph or video. …It's a totally natural thing and it smooths motion from frame to frame and even though …it may not be obvious, our vision contains some motion blur. …Chad Perkins: So shutter speed affects motion blur and exposure. …For example, if I were to speed up the shutter speed then that's going to make the action …crisp because it decreases the motion blur, but it also lowers the exposure which darkens …
