Rochester & Southern SW1200 107 is posed in front of the Brooks Avenue yard office between 9:45 and 10:15 am on September 23, 1987. I made this photograph with a Leica M2 with 50mm Summicron lens on Kodachrome 25 slide film. At the time was doing a lighting test with my Sekonic Studio Deluxe light meter. Puffy clouds were rapidly passing over and intermittently blocking (and diffusing) the sunlight. I made careful notes of changes in exposure which varied by two full stops between ‘full sun’ and shaded.
Incidentally, I published this image on page 53 of The American Diesel Locomotive (MBI Publishing 2000).
