PROPS FACE THE RIGHT WAY: every handheld or used object must be
oriented exactly as its real-world use requires. A person reading,
watching or operating something (a phone, a photograph, a paper,
any device) has its functional side — screen, front, page — facing
THEIR OWN eyes; the camera then sees whatever side the staging
geometry implies (often its back). Show the functional side to the
camera ONLY when the shot text itself stages it toward the viewer.
Never flip, mirror or reverse an object's front and back.
