Portland's skyline over three very different nights

I was working a local convention for a few days, and didn’t wanna make the commute home, so I got a hotel room, and it had an amazing view. I did a study of the weather over the three nights, taking an identical-as-I-could-make set of exposures over all three nights! The first one is the top-level picture.

And of course, I didn’t bring my tripod to the convention, but just like teenagers in desperate need of a bong, I made myself a tripod out of expertly-placed hotel furniture, with my wallet as the lens stabilizer.
