I was on a business trip in Canberra, Australia, carrying my RX100M3 as I used to do. Visiting a local mall, I stood mesmerized in front of that long wall that was staring at me with all these bright sprites. I could not resist, took it at 1/500 sec, f/4.0, ISO 125, no flash, and with a little lightroom ended up with that picture that has now been hanging for year in my office.
