Created a duplicate layer…
To bring out some detail in the interior, I “screened” the duplicate layer (100 percent) in the blending mode, and then masked mask out the screen in all but the interior of the bridge.
Used a PS filter “dry brush” and played till I got the effect I likes.
Created a mask and painted the sign detail (that was lost with dry brush effect) back in.
Finished with a filter in Nik Color Effex (brilliance and warmth) to bring out some warmer tones.
