A timelapse two ways shot from the Manzanita Lake campground at Lassen Volcanic National Park (the second time I've visited and the second time that Bumpass Hell has been closed). First a regular 4K timelapse looking up from the campsite:
The second version is the same footage in HD where each frame is the cumulative maximum pixel value of all the frames up to the current frame (so it builds in star trails as the video runs):
A relatively pleasant Sunday in San Francisco, which means the second you turn your back fog and low cloud are going to swoop in:
The first part of the video is looking west toward the ocean. Once any trace of blue is obliterated we turn south to see fog rolling over San Pedro Mountain near Pacifica and increasingly gloomy cloud cover over the French Chateau Sanatorium (which I think of as the West Portal Retirement Castle). This is a deeply strange building, nestled in a hollow and surrounded by trees. Most of the time you don't see it and then suddenly, on the right street at the right angle you're startled to realize that there is a massive chateau hiding in the neighborhood.
(It's the first project I've completed after upgrading my upgrade-proof laptop with a 1TB SDD, some cat fur and about a half pint of blood. I'm amazed it even boots. There is a tenth circle of hell for laptop designers who decide to hide the hard drive module under two tiny ribbon cables secured with ribbon cable eating tape. And thanks for the fake screws.)
