I had a full day in Salzburg at the tail end of a week-long winter exploration of Austria and Bavaria.
Standing on the banks of the nearly frozen Salzach, I made this view of a DB (German Railways) Regional Express set running empty from the Salzburg Hbf.
Although the sky was clear above, an inversion layer had trapped pollution near the ground giving the light a brown tint.
Salzburg is near the border with Germany and German and Austrian services overlap in this area.
Stark winter light suits black & white photography.
Back in January (2019), photographer Pat Yough and I made a day of photographing New England Central between White River Junction, Vermont and Leverett, Massachusetts.
Among the trains we photographed was freight 611, the Brattleboro to Palmer turn.
I made these views near Northfield, Massachusetts on Fuji Acros 100 black & white film using a Nikon F3 with 50mm lens.
To maximize tonality and detail, I used a split-development process, first soaking the film in a very dilute mixture of Kodak HC110, then a more concentrated mix of Rodinal.
The combination of snow on the ground, very cold temperatures, and low light make for excellent photographic conditions, if you can bear to be outside.
I exposed this view of New England Central 3476 shortly after sunset in Palmer, Massachusetts.
The snow reflects light from below, thus providing greater illumination of shadow areas that under ordinary conditions would be underexposed at this time of day.
Cold temperatures and clear overhead conditions result in a inversion effect, which traps particulates and other airborne impurities that acts as a light filter resulting in a scene with more red and magenta spectrum than normal.
This effect is intensified at sunset because the sunlight has to pass through much greater amounts of polluted atmosphere because of its relative angle to the ground.
To make the most of these lighting conditions, it helps to set the camera white balance to ‘daylight’, since ‘auto white balance’ while tend to cancel out the effect of the rosy lighting conditions.
