So I went to the church again but this time there were baptizing babies in mass. I don't know why babies could be baptized in mass, but that was what was happening there. So I was lucky!!!
So walking around the church, this man (an old traditional photographer) turned his head like 90 degrees and pointed directly towards my very noticeable camera (Nikon D700 with grip and 70-200 f/2.8 lens) with lot of surprise, envy, anger and resignation. All at the same time. A second later, he turned his head back to what he was doing (his job) exactly with the same furiousness, disgusted and contemptuous. Few minutes later, he went and sat there, with his old analogic camera, flash and weighted battery (where he's resting his hand. There is a cross in that hand as well).
