At 1:15:37, just as Bill Paxton's character tosses a sheet over Mary Beth McDonough's character on table, there is a visible flash of light coming from the right side of the screen along with a click that indicates a photographer on set likely snapped a still shot while filming commenced.

When Greg is arguing with his mother and father about Mr. Andrews in the flower shop, a shadow of a person at the right side of the screen can be seen appearing, probably a cameraman or a crew member.
