Across the street from my "Doors With Character" shot is this power station (the river and falls are behind this building). There are three or four very large turbines in this building that you can see through the glass windows (you can't see them in this shot though). It was the "Danger" sign that caught my eye, not the doors. The doors are pretty standard. I really like the signs and the brick, I added a bit of gritty processing to get this affect and am pretty happy with it. I might mess around with this shot in LR 3, the use of grain could add a bit to this shot.
