In July 1994, I was on a grand adventure driving from California to Wisconsin to begin a new job at Pentrex Publishing.<\/p>\n\n\n\n

I had several weeks to make the drive and plotted a course designed to inspect and photograph railways along the way.<\/p>\n\n\n\n

Three years earlier my pal TSH and I had visited the Montana Rail Link where were spent a morning making photos on Winston Hill east of Helena. Movements on this former Northern Pacific line was still protected by General Railway Signal upper quadrant semaphores.<\/p>\n\n\n\n

So on July 10, 1994, I revisited Montana’s Winston Hill. Among my photos that day was this one made as part of a sequence showing a westward BN freight descending toward Helena.<\/p>\n\n\n\n

I was working with my Nikon F3T loaded with Kodachorme 25 and fitted with a Nikkor 35mm PC (perspective control lens) and a circular polarizing filter.<\/p>\n\n\n\n

At the time, I would apply the polarizer to better balance the contrast between shadows and highlights in back-lit situations on bright sunny days. Notice the effects of the clouds and back lit foreground flowers.<\/p>\n\n\n\n

Among the challanges of this arrangment is that it reduced the working ISO of the film from 25 to about 8 (which is extremely slow. Today, I typically work with ISO 200 or higher in digital format).<\/p>\n\n\n\n

In this situation a motion blur benefits my illustration, as it shows a ‘clear’ signal ahead of the westward train.<\/p>\n\n\n\n
