Camera attributes and methods (expression reference)
Camera
objects have the same attributes and methods as Layer objects, except for source, effect, mask, width, height, anchorPoint, scale, opacity, audioLevels, timeRemap,
and all of the material properties.
- pointOfInterest
- Return
type: Property [3].
Returns the point of interest values
of a camera in world space.
- zoom
- Return
type: Property.
Returns the zoom values of a camera in pixels.
Here’s
an expression for the Scale property of a layer that maintains the
relative size of the layer in frame while changing the z position
(depth) of a layer or the Zoom value of a camera:
cam = thisComp.activeCamera;
distance = length(sub(position, cam.position));
scale * distance / cam.zoom;
- depthOfField
- Return
type: Property.
Returns 1 if the Depth Of Field property
of a camera is on, or returns 0 if the Depth Of Field property is
off.
- focusDistance
- Return
type: Property.
Returns the focus distance value of a camera,
in pixels.
- aperture
- Return
type: Property.
Returns the aperture value of a camera, in
pixels.
- blurLevel
- Return
type: Property.
Returns the blur level value of a camera
as a percentage.
- active
- Return
type: Boolean.
Returns true if the camera is the active camera
for the composition at the current time: the Video switch  for
the camera layer is on, the current time is in the range from the
In point of the camera layer to the Out point of the camera layer, and
it is the first (topmost) such camera layer listed in the Timeline
panel. Returns false otherwise.
