Salut Christine My apologies - keystoning is a term sometimes used to describe converging verticals - it refers to the wedge shaped 'key' stone that locks the top of a stone arch. It's actually inaccurate as a key stone diverges rather than converges. I was in two minds as I agree that it is not such a problem here, especially with the curved line across the top to balance it. Of course, I'm merely envious of anyone who has the choice between a G2 and an M6! Sigh. Andrew > >> Christiane Roh - London, British Museum >> I love bw architectural.
