Thanks Instography for the advice.

Not entirely sober taking this, with the little snappy camera which had just fallen on the floor. When I wiggled the contrast a bit and turned it into mono I started to enjoy it a bit, but I thought still looked a bit rubbish. But the expert's suggestion that I crop it further (whether or not this is exactly what was suggested) has, I think, turned it into something.

Lovely wedding.

edit - and now I've cropped it even further.
