I often when switch to new camera find it points at nothing I recognize, I cannot orient it because don't know what it's looking at. is there a fix ?

The face camera is always oriented on the selected figure. If it isn't, use the camera restore to put it back (this also goes for the pose right-hand and left-hand cameras). For the other cameras, you might have to back it up a bunch to see something in the scene to help orient it again. It might help to restore those too, but that will depend on where your stuff is in relation to where the camera originally points.

if you don't remember how to restore a camera, select the camera and then go to edit>restore>camera (or press command,shift, h)
