A Midsummer Night’s City

In the Berkeley Hills, above the National Lab’s Advanced Light Source, the view over Oakland’s twinkling night sprawl entrances. Look at all of those light-emitting objects! As LED lights have replaced sodium vapor models, I’m particularly fascinated in the shift as cities glow white, instead of orange.

Convertible in the Hills

“All things are transient,” said my scientific collaborator, with just a hint of irony. From up in the hills at Berkeley Lab, where we study the way that light and matter interact, he meant it in three senses:

  • We use “transient absorption spectroscopy” to study the changes in a material after it is exposed to light. The new states we create are transient.
  • The gentle blue-hour conditions of this picture are transient; the light was completely different ten minutes later.
  • Berkeley Lab sits atop the Hayward Fault; a large earthquake could topple the lab at any time.

In the face of all of that transience… Might as well go for a drive.

Leafy Window to Oakland

My past couple of posts have been images of San Francisco, foregrounded by nature and suburbs—the style I like to call a “civilization gradient”. This image similarly presents downtown Oakland, California, past the hilltop homes and Cal fields of Strawberry Canyon and through the invasive alien leaves of Berkeley Lab’s eucalyptus trees. The HDR processing techniques that Brendan and I use are perfect for settings like this, with an array of light intensities across a broad landscape.

Birdblur

If this week on Decaseconds has had a theme, it has been structures suspended over water at sunset. It has also been a week of long-exposure shots that live up to the site’s title. Hoards of gulls riding on the waves are reduced to weird ghost-blurs in the foreground of the San Francisco Bay Bridge, Yerba Buena, and the Port of Oakland.

Campanile Bars

Beyond Sather Tower’s bars and columns is Telegraph Ave. and the city of Oakland. I never forget that view, but I do somehow always forget the red tiles at the top of the campanile. I guess my brain abstracts away the details, even when they’re a major part of the scene.
