You can tell when the sun is out because the pictures become nice and crisp. Scotland seems to provide a particular challenge for photos because the amount of light doesn’t correspond particularly well to the settings you would normally use. Most places get darker when clouds block the sun, but somehow in Scotland, the light just gets more diffuse. I never thought to distinguish between ‘light grey’ and ‘dark grey’ skies before I came to Scotland. Here, though, ‘light grey’ skies characterise many nice summer days. Sun is the best, of course, but I’ll take what I can get.
Some cities have pigeons. St Andrews has crows.
