Sizing and positioning an image plane
By default, an image plane fills the camera view with the entire image. You can size and position an image plane so that only a portion of the image appears or so the image appears in a specific region of the camera view.
Use the Image
Placement parameters in the Camera Editor to
size and position an image plane (see Image Placement in Windows
> Editors > Cameras), or pick the image plane (Pick > Object Types > Image Plane 
) and use the Transform tools
to transform it.
You can mask an image plane so that only portions of the image are visible. Use the Mask parameters in the Camera Editor to mask an image plane (see Mask in Windows > Editors > Cameras).
