The best days to photograph industrial areas are Sundays and public holidays… that way I’m just about guaranteed no one being around and those horrible questions of what I’m actually doing taking photos of (conveniently) their doors, fire escapes, electrical boxes and any other suspicious thing you can think of! Mind you, I’m sure most of it is in my head, as I’ve only been questioned once in the last 3 years (although it’s possible I run away too quickly for people to catch me?!), and that was by a cleaner. On a Sunday. And once I told him I was taking a photo of the door and that I liked symmetry he proceeded to tell me he liked symmetry as well and to go down and around the next street, he thought I’d like it. My only other “confrontation” was when I was taking photos of someone’s gate and his neighbour rang to tell him… I’d left by then so the owner proceeded to chase me up the hill and want to see my photo. For some reason he seemed quite disappointed that I found his gate interesting.
