Illustration of a simple three-axis gimbal set; the center ring can be vertically fixed. A gimbal is a pivoted support that permits rotation of an object about an axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first ...
Usual meaning is the reciprocal of the distance between two just-distinguishable subject details. [7] S or TV: Shutter priority or time value. Automatic exposure mode where the photographer sets a shutter speed, and the AE firmware automatically sets the appropriate lens aperture. [4] SC: Soft Capture. Capture of light emitting objects as the ...
Gimbal heads are designed mainly for long, heavy telephoto lenses, and are often used for wildlife or sports photography. Their primary feature is the ability to balance the camera and lens within the tripod head and use tension controls to simulate a "weightlessness".
Other head types include the gimbal, fluid, gear, alt-azimuth, and equatorial heads. Fluid heads and gear heads move very smoothly, avoiding the jerkiness caused by the stick-slip effect found in other types of tripod heads. Gimbal heads are single-axis heads used in order to allow a balanced movement for camera and lenses. This proves useful ...
Gimbal lock is the loss of one degree of freedom in a multi-dimensional mechanism at certain alignments of the axes. In a three-dimensional three-gimbal mechanism, gimbal lock occurs when the axes of two of the gimbals are driven into a parallel configuration, "locking" the system into rotation in a degenerate two-dimensional space.
A handheld steadycam or gimbal may also be used for smaller scale productions. The camera is then pushed along the track while the scene is being filmed, or moved manually when using a handheld rig. The effect can be used to create a sense of movement, to follow a character or object, or a sense of immersion to draw the viewer into the action ...
The second gimbal, inner gimbal, is mounted in the gyroscope frame (outer gimbal) so as to pivot about an axis in its own plane that is always perpendicular to the pivotal axis of the gyroscope frame (outer gimbal). This inner gimbal has two degrees of rotational freedom. The axle of the spinning wheel (the rotor) defines the spin axis.
The science of photography is the use of chemistry and physics in all aspects of photography. This applies to the camera, its lenses, physical operation of the camera, electronic camera internals, and the process of developing film in order to take and develop pictures properly.
