I have had the luck to see a few really good sunrises and sunsets in the past week or two as the seasons really change from summer into autumn. Usually when I see a good sunset I do not have my camera on me, but I had a lucky 36 hour period when I saw two good sunsets and a decent sunrise as well.
Sunset over Walthamstow.
Sunrise over Canary Wharf (Yes I know, I actually caught a sunrise !)
Sunset over the Thames and Cannon Street rail bridge.
