Grey sky, mid-morning, mid-October. This is the light most people complain about and then shoot in anyway, because you don’t get to reschedule a trip around the forecast. It’s also the only light that renders a square like this one without tearing the exposure apart. Look at what the cloud cover is doing. The pale plaster on the west range keeps its texture. The arcades underneath aren’t black holes. The dark Gothic towers of the Týn Church hold detail instead of going to silhouette, which is exactly what happens to them against a clear blue sky at this hour.
