Everything changes when you add "Motion"

Digital Photography
really fast shutters stop motion as on athletes running, etc.
use Photoshop for image manipulation because RAW format is capable of anything.

Digital Cinematography
slow shutter stops motion as on athletes running, etc.
use as many effects "in camera" as possible because of high compression rates.

Please add to this list of differences between the mediums. Thanks!
 
slow shutter stops motion?
I don't get it. Slowing your shutter speed will just make action shots blurry.
I personally view photography and cinematography as more similar than they are different, whether they be analog or digital. The main difference I would say is camera movement. Camera movement with cinematography has to be paid closer attention than that of still photogrpahy. OTher than that, I shoot both still and motion almost exactly the same.
 
Just a typo in the second. Gotta be. Unless they mean using a sloooow shutter will result in "stop-action" type images, but the should make it more clear...a slow shutter, not a long & slow shutter.

Na, I meant what I wrote. Probably could have chosen better words, tho.

180-degree shutter @ 6fps (1/12 exposure, I believe):

Still not following you.
a 180-degree shutter is not a slow shutter, it is a fairly standard shutter in shooting film. WHat do you mean by stopping motion. THe slower the shutter speed, the more blurred the subject. ahh, but now I see that you were saying at 6fps. That changes things, but I still dont' see how the motion is stopped. When playing back this clip, it would play back fast and blurry.
I guess when I think about stopping motion I always think of a fast shutter, wheather that be a 90-degree shutter at 24fps, or 1/1000 shutter speed shooting stills. Both of these freaze the action, the only difference is that when shooting motion pictures, the action is frozen over and over and over and over . . . giving it a very stucotto look.
I guess we are probably looking at the same thing, but have different ways of looking at it. But I do see where you are coming from.
 
Freesing motion...

Freesing motion...

From the example, the camera appears to be tracking the subject. The subject is 'frozen', but the background is blurred due to the slow shutter speed, frame rate, etc.

I don't know if this is what was meant by 'freezing'...
