Crystal World

A timelapse of four containers growing crystals from the National Geographic Mega Crystal Growing Lab. The sequence was shot over two weeks (one frame every four minutes, running at 60 frames per second).

It should have taken less time. They recommend a growing area that is at least 68 degrees. This shouldn't be a problem with most of the country suffering record temperatures under heat domes if not actively burning in record breaking wildfires, but San Francisco is experiencing its coldest summer in more than five decades so two weeks seems like the minimum.

Other than not attempting to grow crystals in San Francisco, the other lesson learned is that you really want to use the two silicone cups included in the kit. We tried a pint glass that just grew fuzz (possibly due to the age and pitted nature of the glass) and a jam jar that grew cute small crystals that then made a decent attempt at escaping down the outside. I think three weeks and it would be a full J. G. Ballard situation.

Second batch. This time shot from above. It's still cold, so this is three weeks, 5 min interval and 60 frames per second for the timelapse:

Third batch. We're well into September but San Francisco is still bathed in fog. This is still at 5min per frame, but only took two weeks as I moved the lights closer in. For this timelapse I experimented with Adobe Super Resolution so the video has the same sequence three different ways (I wrote a separate post on the Super Resolution experiment).

Time lapse of stars and the milky way over Redding, California. Nice to have got the milky way as there is still a fair bit of light pollution in this area. Shot over three nights in July 2021. Shot on a Sony A7C with 20mm f1.8 G lens. Post processed in Lightroom, LRTimelapse, Resolve and Filmstro Pro.

Easy and spectacular hike around the perimeter road of Angel Island. Around five and half miles, although gets a bit longer if you add a detour or two, and there is something interesting around every corner. Just make sure you don't miss the last ferry back.

(Previously: Mt. Livermore on Angel Island)

The Sundial Bridge in Redding, California crosses the Sacramento River while also providing the correct time one day a year (the Summer Solstice) assuming it's a sunny day (a pretty safe assumption for Redding).

I'd rather get rid of the electoral college and have a national, ranked choice vote but this is interesting.
