Design trends come and go, and from behind the lens, I’ve noticed quite a few. Lately I’ve detected big changes in the world of metal finishes. There was a time, not that long ago, when all metal had to be of the stainless steel variety, preferably brushed, but polished or galvanised would do. Chrome too was popular. Put simply metal had to in a silvery hue. Anything brassy was completely out, sharing as unfashionable a reputation as flared trousers. As for copper, it remained largely invisible in the design world, maybe because of its reputation for being hideously expensive, although that’s not usually a reason to dismiss a material. Then, not so long ago, brass made a remarkable comeback, and so I suppose it was only a matter of time before copper hit the big time. Over the last year on shoots, I’ve spotted light fittings, bathtubs, worktops and architectural cladding, all in this rich, distinctive orange metal. Let’s take a look.
