Dusk at Coteau.

The blue hues of evening offer a wonderful time to photograph idling locomotives.

Photographer Tim Doherty, arrived at the junction at Coteau, Quebec in time to make the most of dusk.

A set of Canadian National GP9RM diesels were resting between runs.

I made this view on Fujichrome with a Nikon F3 and a telephoto lens mounted firmly on a tripod. Here’s a tip: when making this type of photograph, despite the need for a long exposure, it is better to lean toward over exposure than risk losing data to the inky blackness of under exposure.

This slide was among those that sat in the dark for more than twenty years. Last week, I scanned with my Nikon LS5000 scanner, and processed the TIF file uisng Adobe Lightroom.

This is complicated lighting situation; two distinct types of artificial light mixed with the blue glow of dusk. The harsh yellowing sodium-vapor lighting is especially problematic.
