photographing children in public spaces. Taking photographs on private property is also legal. The landowner may, as a condition of granting entry to the private property, choose to place conditions or restrictions on photography, but the only consequence of failure to comply with these conditions is the photographer being required to leave. Landowners and their agents cannot inspect or delete, or require the deletion of, photographs taken this way.
