An HDR photograph of the Calatrava designed Margaret Hunt Hill Bridge across the Trinity River near downtown Dallas. I was setting up the tripod when the train came steaming along over the trestle between me and the cable-stay bridge. I had to rush the picture before the train went by and didn’t get the focus right… better luck next time. This is a tone-mapped image taken from a single RAW exposure. Since the train was moving at a pretty good clip, I couldn’t use a three-exposure HDR image – I tried it and there were too many strange effects around the train because it was in different spots in each exposure.
