I was on a photo-shoot last week, in our photographer's studio. Like many, his studio is filled with interesting left-overs and obsolete equipment. And it reminded me of my snail's-pace collection of light meters. I haven't got many and the few I do have have been brought together over, well, more years than I can be bothered to work out. Like lots of the stuff I collect I have no interest in actual value. My light meters are, almost certainly, of no significant value; I strongly suspect a couple of them were just run-of-the-mill devises and no self-respecting pro would be seen dead with them. That doesn't matter to me. I'm not even that into photography, not really. I carry a very average compact digital thing and am very happy with it. To be honest, I just think they're great objects. They could be for anything for all I care; they're just great, pocket-size, twiddly objects.
