  • Captured with a Rodenstock 50mm/4.0 HR Digaron lens (@ f/5.0) and the Phase One IQ4-150 back, shifted vertically by 12mm.

    This is a straightforward, somewhat abstract, composition, emphasizing scale and lines. It converges out of sight below the foreground pier, suggesting an infinite roadway.

    I shot this several times, day and night, and the nighttime image, in which the steelwork under the bridge is closer in brightness to the sky, was much more interesting. The cloudy night helps, too.






  • Captured with the Rodenstock 138mm/6.5 HR Digaron-SW lens (@ f/7.1), Phase One IQ4-150 back (@ ISO 50, 1/125 sec), Cambo WRS 1250 camera. Stitched panorama of two images, shifted left and right +/- about 18mm.

    This view reminded me of Malvina Reynolds’s famous 1962 song (though she was inspired by another San Francisco neighborhood - Daly City). If you look closely, the houses don’t quite “all look just the same”, but somehow, on the hillside there’s more uniformity than there is up close.





  • Captured with the Rodenstock 90mm/5.6 HR Digaron (@ f/7.1) and the PhaseOne IQ4-150 “Achromatic” back. 12mm of vertical shift kept the geometry in line. The sharp lens and achromatic back reveal a lot of detail zoomed in at full resolution (full res is downloadable on flickr).

    This is a very simple composition, the frame filled with the Memorial from roughly the perspective shown on the $5 bill. The National Parks Service does a superb job lighting the site.





  • Telegraph poles with multiple “code lines” were once a common feature along American railroads. They are distinguishable from ordinary power or telephone lines by their multitude of cables, often occupying several crossarms. The wires typically include a power bus plus separate leads for the signals along the route, with various more efficient encodings used as technology improved.

    They’ve been mostly supplanted by more modern SCADA systems that don’t require so many individual wires.


  • Captured with a DSLR and 24mm shifting lens (vertically shifted just a bit) on a hot day in the Mojave desert.

    This is a simple composition, characteristic of the early 20th century Precisionist school. There’s little in the frame that isn’t essential. The pylons, wires, and tracks all converge at a vanishing point at the edge of the frame, suggesting, but not showing, a more expansive network of wires, tracks, and, for better or worse, human dominance over nature.




  • It’s generally simpler to capture tall skyscrapers like this from a distant vantage point; the classic photos of WTC are usually shot from Brooklyn or New Jersey. But here I wanted to show it as it’s seen in the neighborhood. The foreground buildings look taller in the frame, but the (much taller) One WTC tower still stands out, given its uncrowded position in the skyline, as if its neighbors maintain a respectful distance.


  • This was captured with the Rodenstock 70mm/5.6 HR Digaron-W lens. A large image circle allows room for considerable movements, used here to swing to selectively focus on the WTC tower. A polarizer darkened the clear sky a bit, as well as taming some of the highlights reflected off the glass wall of the tower.

    The shape of the new One WTC makes the light catch it differently throughout the day and in different weather. I made several exposures at different times before settling on this one.






  • San Francisco’s Treasure Island is a weird place. An artificial island built adjacent to Yerba Buena Island in the middle of the Bay Bridge, it initially hosted the 1939 World’s fair, with plans to then use it for the city’s main airport. At the start of WW II, the US government appropriated it for use as a Naval station. After the Cold War, the government returned the island to the city. It was extensively contaminated by radioactive waste from decontamination training conducted on the island.
