A central shutter is not a type of shutter as such, but describes the position of the shutter: it is typically a leaf shutter (or simple leaf shutter), and located within the lens assembly where a relatively small opening allows light to cover the entire image. Leaf shutters can also be located behind, but near, the lens, allowing lens ...
The rule states that the camera should be kept on one side of an imaginary axis between two characters, so that the first character is always frame right of the second character. Moving the camera over the axis is called jumping the line or crossing the line; breaking the 180-degree rule by shooting on all sides is known as shooting in the round.
A high-angle (HA) shot is a shot in which the camera is physically higher than the subject and is looking down upon the subject. The high angle shot can make the subject look small or weak or vulnerable while a low-angle (LA) shot is taken from below the subject and has the power to make the subject look powerful or threatening.
Dutch angle. Also called Dutch tilt, canted angle, or oblique angle. A type of camera shot where the camera is set at an angle on its roll axis so that the shot is composed with vertical lines at an angle to the side of the frame, or, equivalently, so that the horizon line of the shot is not parallel with the bottom of the camera frame.
A tight shutter angle will constrict motion blur. A wide shutter angle will allow it. A 180° shutter angle is considered normal. So for instance, at 24 fps the frame interval value is 0.04167 second ( = 1 ⁄ 24). Using an exposure time of 1 ⁄ 50 second gives a shutter angle value of 173°, very close to 180° (normal motion blur effect).
Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.

One then reframes the scene and fully depresses the shutter to take the photo. Unlike other modes, this also sets focus and requires two separate metering/focus stages. A-DEP: [3] Canon also offers A-DEP (Automatic DEPth of field) mode on some cameras, which sets the depth of field and focus in a single shot. However, this requires lining up ...
