I went for another London Day Trip on Saturday. This included a little Tunnel Hunting. I had spotted this tunnel in Embankment Station before but I was not satisfied with the symmetry of the shots I took then. First task was to find the tunnel again in the maze. I eventually found it further down en route to the Bakerloo Line.

For the title the circles got me thinking of Accelerators.

The picture was taken handheld with a Sony A700 with a Samyang fisheye lens at 8mm and f5.6. I took 3 pictures for HDR.


The 3 images at 2EV separation were outputted in Photomatix fusion method Natural Adjusted preset.


First a little straightening and cropping was done to get the symmetry just right.

Topaz adjust was used with vibrant presets group with crisp preset to bring in more detail. The effect was applied on a layer with a layer mask which I used to exclude some of the ceiling from the enhancement.

Brightness increased a little excluding the people on the right.

Vibrance increased 31 points

Layers flattened before going on to sharpening.

Duplicate layer Noiseware Pro and a little sharpening.

Second duplicate layer with mask to apply extra sharpening and contrast with low amount and high radius using Unsharp mask (Clarity Effect) The settings were 40 amount and 40 radius. A layer mask was used to exclude this effect from some highlights and parts of the ceiling.

The Healing tool was used to remove some litter. The clone tool was used for tidy up.


Below are the Before and After images. First the original. Then the tonemapped image and then the final result.
