This wasn’t taken this week, but I’ve had the footage for a while and thought this was a good opportunity to do something with it.
The first thing that catches my eye in this timelapse is the vastly varying brightnesses as the clouds pass over the sun. It’s not something that we usually notice at normal speeds, but sped up it’s obvious.
Near the end, just before the sun dips out of sight, we can start to see the reddish tint that would become a beautiful orange sunset were it not for the clouds. This is most obvious on the bare brick wall on the left hand side of the image.
Once the sun disappears behind the clouds, the ambient light on everything immediately becomes blue, as the still-bright sky becomes the main, very diffuse source.
