Details : Nikon D5100 | Nikkor 35mm F1.8 | 1/4s | f/6.3 | ISO 100
Photo taken freehand with a relatively long exposure time (1/4s), while we waited in St Pauls metro station (London). To minimize movement of the camera, I put my elbow on my leg. I triggered a burst of five pictures when the train arrived.
HDR process was done with Oloneo PhotoEngine directly on a single RAW file (NEF), the contrasts have been enhanced with Color Efex Pro and a portion of the image was desaturated with Lightroom local adjustments.
