Coastal

Frame from Coastal Timelapse

An abstract timelapse of the California coast.

The sequences were shot over about six hours using a Sony RX100V, f5.6, 1 second exposure, ND3 filter and ISO 80 to around 250 depending on the light. Most of the frames are from the Marin headlands, one sequence is from Sutro Baths in San Francisco.

Post production used Lightroom and LRTimelapse. I skipped LRTimelapse rendering and wrote a custom application to mirror the frames (for this video mirroring is left/right top/bottom and for one sequence both). I then used ffmpeg to render each mirrored sequence and Premiere Elements to edit them together. Finally I added music with Filmstro.

If anyone is interested in the mirroring application post a comment below and I'll tidy it up a bit and release it.

This timelapse is absolutely inspired by the main title sequence for Bosch on Amazon Video.

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.
