# Yaw

From PanoTools.org Wiki

Panning angle, left-and-right. See also Pitch and Roll.

Yaw is the horizontal rotation angle of the camera and part of the panotools Image positioning model.

If shooting a panorama you rotate the camera horizontally (around a vertical axis, TrY). You will treat one image as an anchor image[*] which is considered to have yaw = 0. The angle you rotated your camera relative to this image is its Yaw value.

For a typical 360° panorama the yaw difference from one image to the next can be estimated by dividing 360 by the number of images.
