Lassen Star Trails

Star trails from the Manzanita Lake campground at Lassen Volcanic National Park

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):

Draw the rest of the Hummingbird

Generation three thousand of a genetic algorithm learning to draw a hummingbird

A genetic algorithm learns to draw a hummingbird:

The video is an animation of three thousand generations of evolution. It starts with a random mix of line segments which are then mutated by adding or removing lines and by changing the start, end and color of existing lines. Each generation has 32 individuals. The best individual is mutated to create the next generation.

For this implementation the best or fittest individual is the one with the least error on a pixel by pixel comparison to a stock art drawing of a hummingbird. Because I care more about the shape than completely filling in the drawing an error outside the figure is penalized three times more than a gap inside the figure.

Color is mutated each generation but not selected for, so it's just changing randomly.

Bay Model Tide 360 Timelapse

Bay Model in Sausalito CA

The Bay Model in Sausalito is a two-football field sized working model of the San Francisco Bay and Sacramento - San Joaquin River Delta. Here's a 360 degree timelapse of the model in action so you can see the tide coming in and out (best in a VR headset but you can pan around as well):

Shot on a Ricoh Theta S and post-processed in LRTimelapse and Adobe Lightroom.

June Gloom

Gloomy cloud over the French Chateau Sanatorium

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.

Star Trails

Star Trails

Here's a different take on the timelapse I posted yesterday (Jupiter from Casini Ranch):

For this version each frame is built from the cumulative maximum pixel value for all the previous frames. So it's like a long exposure with nice star trails (and Jupiter, and at various points a couple of satellites and a plane).
