Fountain in the sun, Darling Harbour, Sydney, Australia.
I was experimenting with the way sun shone through water and how the camera handled it. I think this was a particularly stunning effect!
I should've taken a longer video, but in my enthusiasm to experiment, I kept moving the camera around...and now I live over a thousand kilometres from that fountain, and I haven't found another fountain with the water at the right height at the right time of day... but I keep looking.
[NB: No, I wasn't looking into the sun whilst filming...]
