<human>: Hello. My [F/27]  fiance [M/28] and I are getting married next May, and we can't wait! We recently went to his cousin's wedding which was a nice and classy affair, very traditional. 

At the wedding, one of my fiances new cousin-in-law's [M/33?] was taking pictures like a mad man with his camera: asking people to pose, getting up during the ceremony, interrupting people at the reception, etc. As a guest you could have mistaken him for the paid photographer. I found this to be very intrusive, and also rude to the paid professionals that were hired to shoot the event. 

I don't think he meant any harm, but really it seemed to be inappropriate. He also is  kind of a goofy dude, so he wouldn't be someone we would consider hiring as the main photographer. 

We have 2 more family weddings before my fiance and I get married next spring, if he continues this photography at the other weddings I am going to be very annoyed. Not to mention, we are paying a butt load for a photographer, because apparently thats the going rate these days. How do I let my fiances cousin-in-law know that he is not welcome to shoot pictures like that at our wedding?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My fiances cousin-in-law brings his hobby camera to the family weddings and takes way too many pictures, getting in the way of the professionals. How can I ensure he doesn't do this at my wedding?
