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.
Focal-plane shutters are usually implemented as a pair of light-tight cloth, metal, or plastic curtains. For shutter speeds slower than a certain point (known as the X-sync speed of the shutter), which depends on the camera, one curtain of the shutter opens, and the other closes after the correct exposure time.
The lens was swung towards right, in order to keep the plane of focus along the train. The sensor plane, the lens plane and the plane along the train all intersect to the right of the camera. Varying the distance between the lens and sensor or film plane across the field of view permits focussing on objects at varying distances from the camera.
Air-to-air photography is the art of photographing aircraft in the air, while using another aircraft as a photo platform. [1] The subject aircraft is photographed while both aircraft are in flight. This allows the photographer to position the subject in specific locations and angles to get the most desirable shot.
The camera angle marks the specific location at which the movie camera or video camera is placed to take a shot. A scene may be shot from several camera angles simultaneously. [1] This will give a different experience and sometimes emotion. The different camera angles will have different effects on the viewer and how they perceive the scene ...
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).
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.
The entire subject can be in focus, even if it is not parallel to the image plane. The plane of focus also can be rotated so that it does not coincide with the subject plane, and so that only a small part of the subject is in focus. This technique sometimes is referred to as "anti-Scheimpflug", though it actually relies on the Scheimpflug ...
