I cannot remember my script when I do a head shot.
Very surprising because I have community theater acting experience. But there is something about looking at a camera lens that makes my mind go blank. (Couldn't be that being 74 years old involves memory loss, hm-m-m?)
And the feedback from my test video was that I need to adjust my camera so I do not appear to be looking down.
One thought is to place my camera on the keyboard, place the whole laptop with the camera on a stack of books and program my editor to scroll my script behind the camera.
Seems to me there should be a better solution. What do you do?
