@lyndemc Thanks Denise. I edited this photo with a touch of 'Dark Contrasts' in Color Efex (first time I've ever used this - although I often use the Silver Efex for improving black and white photos). Than I put the slight frame around it (as you once taught me to do ...) with Photoshop and added my bit of text.
@jamibann So the tunnel and flooring really is gray like this. On closer exam, I'm seeing some iridescent colors on the bricks to the left. That yellow wall really draws the eye into the subway. (I like that Dark Contrast option in Color Efex too.) Thanks for the extra info.
