I exposed this image of a Thalys at speed crossing a arched bridge over Hollands Diep minutes before the fading orange ball of the sun melted into North Sea coastal fog.
Thalys is an international high-speed train branding applied to services connecting Amsterdam-Brussels-Paris, and Köln-Brussels-Paris. Technologically speaking the train is a French-built TGV, but specially painted and decorated for Thalys services.
This was an evening run from Amsterdam to Paris. Hollands Diep is the coastal estuary fed by Rhein and Meuse Rivers. This bridge features a pronounced sweep up and over the water. Beyond it is an older (and busier) truss that has two main tracks for ordinary rail services (freight and passenger).
I panned this train with my Canon EOS 7D fitted with f2.8 200mm fixed telephoto. The light was fading rapidly, so I set the ISO to 800, adjusted the white balance manually and pre-focused in anticipation of the fast moving train. My exposure was f4 at 1/250 of a second.
Earlier in the evening I’d seen a Thalys fly across the bridge and I recognized that the structure of the bridge mimicked the paint scheme on the train, so I released the shutter to allow for an arching visual flow between train and bridge. This is accentuated by the low light.
