I walked a total of over 20km in the last few days to go take pictures of a cable car pylon that's lit up in the evenings in the color of the next day's air quality index. Since we're in the summer now, the index wobbles between red, yellow and green. I found many angles to take pictures from, am learning to do long exposures, and the pylon only stays lit for slightly over 2 hours every evening, so I have to come back multiple times. Here it is in red and here in green. I have some more pics that I need to process in Darktable before I can post them.
