Golden Gate Bridge Timelapse

Updated on Saturday, February 19, 2022

Golden Gate Bridge from near Fort Point

Shot from the Marin headlands, the Golden Gate Overlook and near Fort Point. I used an RX10 IV with an ND3.0 filter. Raw images were captured every four seconds with a one second exposure time. Edited with LRTimelapse and scored with Filmstro Pro.

I was expecting a pretty sunny day but ended up with regular showers and some pretty wild swings between sunshine and cold soggy overcast weather. I think the occasional raindrop and the mood swings work quite well, although the wind caused a bit of wobble on the long zoom onto the deck of the bridge.

Global Temperature Anomalies Animation, 1850 to 2018

Updated on Saturday, February 19, 2022

Global temperature maximum anomaly from Jan 2010 to Nov 2018

I made this animation to visualize climate change based on the HadCRUT 4 data (specifically the ensemble median gridded data) from the Met Office Hadley Centre.

HadCRUT 4 provides temperature anomalies in a five degree grid by month and year from January 1850 to November 2018 (as of this post). Anomaly here means deviation from the 1961-1990 average.

In the animation I wanted to capture the full timespan of the data but also show long term trends. Each frame is a month of data and each five degree grid of longitude and latitude is colored based on the maximum cumulative anomaly (positive or negative) for each decade. The range for color is 0 to +/- 20.85 degrees, red for warmer and blue for cooler. This means there is a reset at the start of each decade, the first few years are mostly random noise but by the end of each decade you're seeing the range of extremes.

Spoiler alert - you can spot something happening in the last three decades.

As well as the change in temperature it's interesting to watch the increase in global coverage over time. It's surprising that even the most recent years have no readings for Antarctica. Here's a paper (PDF) discussing the impact of the missing data. The HadCRUT 4 FAQ has more detail on how the temperature anomalies were assembled.

San Francisco from Treasure Island

A timelapse from Treasure Island in the San Francisco Bay.

The first half of the video is looking west from Treasure Island and pans along the San Francisco waterfront. The second half was shot east towards Oakland and includes a storm sweeping in from the north.

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

Updated on Saturday, February 19, 2022

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

Updated on Saturday, February 19, 2022

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.

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.

Animation of a year of Global Cloud Cover

Updated on Saturday, February 19, 2022

Update April 19, 2020: I made a longer, higher resolution version which you can find here.

Animation of a year of Global Cloud Cover

Here's an animation showing a year of global cloud cover (from July 2017 to July 2018) :

The clouds are sourced from the free daily download at xplanet. I run a Google apps script that saves a copy of the image to Google Drive every day (basically the same as this script to save Nest cam images). The hard part was waiting a year to get enough frames. Xplanet combines GEOS, METEOSAT and GMS satellite imagery with some reflection near the poles. Although I didn't need to for this project note that you can subscribe to higher quality / more frequent downloads.

As well as the clouds you can also see the terminator between day and night change shape over the course of the year. This video starts and ends with the Summer equinox when days are longest in the Northern hemisphere.

Where it's nighttime the image is based on NASA's Black Marble. The daytime is based on Blue Marble, but blended with a different older image which has better ocean colors and interpolated daily between twelve monthly Blue Marble satellite images. The result of this is that you can see snow and ice coverage changing over the course of the year. If you look closely you'll also notice vegetation growing and dying back with the seasons.

Rendered in a slightly modified build of Catfood Earth (the main release doesn't know how to access my private cache of xplanet cloud images). As well as combining day, night and cloud images Catfood Earth can also show you earthquakes, volcanoes, US weather radar, political borders, places and time zones. It has been enlivening Windows desktop wallpaper for fifteen years now (as shareware back when that was a thing, these days it's a free download for Windows and Android).
