He's talking total and utter bollocks.Thought I'd post this query here; was on holiday recently at the seaside and walked onto the local pier where there was a film being shot. We joined a small crowd of folk rubbernecking to see what was going on, some of them taking snaps with their phones. I had been taking a few photos further up the coastline and still had the camera (Nikon 1 J5) on the neck strap, but turned off and lens cap on; couldn't see anything particularly worth photographing (although apparently Eddie Izzard had been around earlier) and was about to go when a security chap came bounding over and bent down to me (was a big bloke; I'm not) and told me I couldn't use the camera here and he muttered something about my camera interfering with the crew's film cameras. I shrugged and told him I hadn't used the camera and was just going anyway; didn't notice him speak to anyone else taking photos. Any one know anything about this ? Have seen people using DSLRs/compact system cameras around film sets before with no issue..
