Sodium Emission vs. Rayleigh Scattering

We’re not far from the ninth anniversary of the founding of Decaseconds, and I came upon this arresting image of Berkeley Marina, the Marin Headlands, and the Golden Gate Bridge (never before published here) while searching for just the right anniversary shot. I’m fascinated by the way the orange emission of sodium vapor lamps lighting Berkeley (I’m sure now all swapped for white LEDs) matches the Rayleigh-scattered oranges of the winter sunset. The same wavelengths of light, coming from completely different mechanisms.

Old Town Hall

Prague’s Old Town Hall may appear ancient from its exterior, but its recently-renovated interior includes this dramatic elevator (the four lights are the bottom of the car) in its helical cage.

Old Town Hall, New Elevator

The view from the top (where that elevator leads) is far more traditional. My favorite detail of this big image is the contrast between the enormous, dramatic Prague Castle in the distance and the little shop door in the foreground.

North in the Morning

Cityscapes were the images that first really drew me to photography—those images with seemingly infinite detail. Zooming deeper and deeper reveals trees and cars and people down at street level. Surpassing the current limits in this respect will probably mean a new camera (or a real commitment to multi-shot panoramas.)

Two Bridges

I’m aware that this picture technically contains three bridges, but it is nonetheless an image of the Two Bridges neighborhood just after sunrise. There are so many sunset pictures of New York; I think the dearth of morning shots is correlated with the sleep schedule of the average photographer.
