This picture has been posted before, but I was playing around with it today and like the result. Originally the engine was too dark and lens perspective made the corner of the section house crooked. I was able to use one PS tool to selectively lighten the engine, and a perspective correction tool to straighten up the building.
The result has the look of a painting to it. That's Jeff Stebbins walking back to the engine, and if I remember correctly this was a David Rogers freight charter in October 1997. The snow was interesting but it prematurely knocked a lot of color off the trees.
