One from the archives from a London visit earlier this year. This was taken at the Greenwich foot tunnel under the Thames. No cycling is allowed in the tunnel but luckily for me one disobeyed. 3 images taken rapid fire and merged together in Photoshop using layer masks

Light levels were very low and I could only just get a shutter speed of 1/15 second at 1000 ISO. I used a Sony A700 with a Sigma 10-20mm wide angle lens at 20 mm.

I edited a lot with Topaz using Topaz Adjus Topaz and Topaz BW Effects for the mono conversion. I cropped for better composition and did a slight vignette using Topaz Adjust and using just the vignette feature.
