This is a really fast tip that actually might come in handy if you like shooting at night. If you own a Canon camera and use their strap you may have wondered with the little rubber “thingy” on the strap is used for. It fits right into the slots on either side of the viewfinder to help prevent ambient light spillage when shooting long exposures at night.
