The prints look terrific, Ian, very appealing. I particularly like the wood finish contrast against the white mat with the prints themselves well set off.
One of my B&W triptych, "The Moorings" was in 2001 toned dusky blue (!) and framed in distressed blue-tinted wood (prepared with steel wool, a fine steel bristle brush and ball-peen hammer blows). Why? The buyers were from Greece and the scene I had pictured reminded them of home. I didn't particularly like the effect but of course, "the customer is always right".
Damned lucky you've got galleries that pay you to exhibit! Down here, they commonly lop off 45% commission from any sale and that's after the usual costs of set up etc. (which are often paid up-front). Arts Council grants cover special projects and have mandatory acquittal processes (with some special exemptions) but do not cover framing, presentation and on-costs.
This should be a very interesting thread. A last, we are going to see the best work of the many APUGgers here, including the innumerable masters of B&W and alternative processes. Let's put 'em up under the bright lights for all to see.
