This photograph happens to bring together a number of things I like . . . especially paintings and photography and light and theatricality and recognizing that I must rush to do something (eg get my camera) NOW, or a moment will be lost for ever.
A painting by Michael Ayrton (a study for an enormous mural for the Festival of Britain) sat on an easel by the window. A glance showed that light was pouring in and the window itself was reflected in the picture glass together with part of a sculpture, by complete chance also by Michael Ayrton, which was on the other side of the room.
Happily, I think, I DID run for my camera!
