A simple question. Do you respect "no photography signs", when you can get away with taking pictures.
Yesterday I travelled a long way to photograph a monument ( owned by a public body), that I have wanted to visit for ages. You pay a small sum, they open the monument and I was left to my own devices to wander as I pleased. I packed my cameras in a nondescript small hiking rucksack and went in and took the pictures I wanted.
These photography bans used to be really common here in Italy. They have almost disappeared thanks to the cell phone, making these rules unenforceable. It is really unfathomable how sometimes I can use even a tripod, and I even have had custodians turn lights on for me, my monopod method gets little notice and in the big sites I use IBIS. Then unexpectedly you get "no photography" rules in places that we subsidize with our taxes.
Maybe because I once worked for a news magazine when I came to Italy with almost zero Italian, and learnt to shoot and ask permission afterwards, that I have little respect for these archaic rules.
