On the evening of November 23, 1992, I was poised to photograph the action on Amtrak’s Northeast Corridor at Grace interlocking at Havre de Grace, Maryland.
I was interested in this angle specifically to use the glint light shortly before sunset. Kodachrome film had an exceptional ability to capture detail in the extreme contrast of sunset situations.
Although it had been a clear day, there was plenty of particulates in the air from tens of thousands of automobiles driving I-95 and adjacent roads. Almost invisible to the eye, this pollution acts as a reddish orange filter and changing the quality of sunlight toward the long end of the spectrum. Kodachrome with its red-bias amplified this effect while its great dynamic range maintained excellent detail in highlight areas.
Working with my Nikon F3T and f1.8 105mm Nikkor lens, I had only a few minutes before the sun disappeared behind the trees at the right.
Moments before the light changed, a late-running Florida train bound to Penn Station, New York glided into the scene with a 1970s-era E60CH electric in the lead. Perfect!
I made a couple exposures as the train passed.
