Looking for the valve

A few years ago I was lucky to have been able to get inside the Lloyd's building, although that day I was a bit rushed and with the number of people visiting, I didn't get a good chance to take many photos.
Although I still think there are many angles to discover, here's another one that I like that I took during my walk this weekend.
Even though it has been almost 30 years since it was built, I still think the structure looks modern and unique.

I also hadn't noticed at the time, but the ISO was at 2000. Although I was after a slightly gritty image, it's a testament to the camera that I can use high ISOs without much thought.

ISO 2000, f/8, 1/30, RAW
