Something a little different, this is a tunnel at the Barbican Arts Centre. It is somewhat at odds with the concrete of most of the structure and has a Sci-fi feel to it which I enhanced with a healthy dose of Topaz Glow. The Barbican is a bit of a maze at the best of times with its high level walkways and many residential and cultural buildings. The easiest way to find this tunnel is to go at ground level to the lakeside entrance to the Cultural Centre. There are outer stairs here encased in glass. At the 4th floor this tunnel is opposite the stairs and leads to the Barbican Conservatory in Frobisher Crescent

The picture was taken handheld with a Sigma 10-20 mm lens at 10mm. One image processed first in RAW. I used Photoshop – Filter – Lens Correction – Custom to improve verticals. I decided that the background of buildings and parts of buildings visible through the glass of the tunnel were a bit busy so simplified this by using Topaz Glow with a Preset of Brilliant in White. I used the sliders in the adjustments to this to bring up the blacks in the tunnel supports and also bring up the reds in the brickwork of the floor. The adjustment was applied on a duplicate layer and I used a layer mask to remove it from the end of the tunnel and the rather neat looking large white arrow pointing right.
