[Dr Who] Would you be able to see a weeping angels shadow move?

If they were to run behind a wall, whilst being out of anyones sight, but there was a light source projecting a shadow on the wall, would it be possible to see the shadow move?

Weeping Angles know when they are being observed. They will get quantum locked being watched remotely on camera, so there’s no reason to think they’d move when their shadow is being observed. I’d assume that any form of visual observation locks them. Additionally, who knows if their true forms even cast shadows…the statues are just assumed forms when locked in order to hide. Baby, cherub angels will supposedly giggle and make footstep sounds, but that might just be to screw with you.
