its magical foam core and magical black masking tape that have no problem with light leaks
i suppose a pinhole and changing bag could be used,
but that's no fun

it will turn black-as-night in developer.
these cameras are intended for long (lumen print type)
exposures 1 to 4+ hours so the image projected onto the paper
kind of burns onto the paper.
