Wastwater with Welding Glass

Shot with the K-5 and DA 16-45, and a sheet of Shade 10 Welding Glass. I may upload a colour one, but I'm still playing with it to try and remove the severe green tinge whilst ensuring the colours are natural, so for now the BW one will have to do. Sky has been replaced with one shot a minute earlier from exactly the same position but without the welding glass, in order that the clouds are not blurred by the long exposure.

Benefits from the large view.
