Compressor Plant Cylinder

 

You are looking at one of the cylinder heads in the compressor building. These contain the piston compressing gas for the pipeline to Calgary. They're about 18 inches across and three feet high - a tad bigger than your average modern car. The image works in black and white too but I quite like the contrast between the cool blue/black cylinder side and the bronze coloured fittings.

Editing consisted of some 20 adjustment layers, various curves, straight lines with the white point moved left, Akvis Enhancer toned way down and applied only to parts of the image, and the foreground really burned in.

These cylinders come 3 to a unit, driven by 600 horsepower engines, the building containing more than a dozen units (or 36 cylinders and 7200 h.p. of engine). That ought to supply natural gas to one or two houses...
