...Where are your insights about Camera Restricta ?
Pssst! Do not let the PC nuts hear about it. Next thing you know, they'd quickly go past landmarks and over-photographed sights to... people. If you are photographing a group, it must match the demographics of the locality by race, gender, etc., or the shutter would say "nein, verboten!" If you are photographing a single person, you could, as long as you'd have enough of other demographics present on your memory card prior to that. If not, it will let you keep that shot for the next hour or so, while you are frantically running around trying to add PC diversity to your shots.
