Nick, I used to use black wooden frames much the same as Gary's, I'd guess i have about 60 maybe 00 of those frames, they were used for numerous exhibitions so every so often I would refurbish them.

In more recent years I switched to a more natural wood finish and a framers cut the profile specially for me. I guess I have 70+ 20"x16" and half a dozen 24"x30". These are shown below, part of an exhibition at Photofusion, London (so their lighting).

It's an expensive business, luckily Galleries often pay to show your work, and I had Arts Council funding for production costs, while that isn't for framing any money helps.
