My uncke used ti love taking photos of

[soldierant]

the Firefall in Yosemite (yeah, I'm old) After much trial and error he learned that in order to catch any background he had to use a tripod, take an exposure in twilight, and then come back to it and expose it again for the Firefall itself. I don't know whether urban hermit did that, but I am reminded of it.

Tour photo on the other hand required catching the exact exposure at the exact moment. I honerstly don't know which is more difficult - both are wat beyond me. Congrats
