Still delving into my archives whilst I spend some time editing and processing my Rally photos from the weekend just gone :-).
I'm not quite sure how I missed this one. I have photographed this place many of times and always enjoy going here. The tunnel seems to go on for ever and ever, its on my list to visit now with my fisheye so I can see what results I can get with that lens here.
I tried a different way to process this image and I think the hint of blue/green adds a real cold and empty feel to it as normally the tunnel has a warm yellow glow to it.
Again done in HDR to bring out all the details on the tiles and the dirt. No noise reduction as I wanted to keep the grittiness of image. Once sorted in Photomatix, reimported back into LR4 for final adjustments and this is the result.
