OK. And now you can see that I've cloned out the building on the left, and the "no parking sign. I've also applied some exposure correction and contrast adjustments, you can do this with shadow/highlight tool, or curves adjustment.
Now, let's apply a slight tone to this image. I like to use "luminosity toning."
Do cmd-option-~ (pc: ctrl-alt-~) to select just the luminosity. You'll see that the "marching ants" are signifying your selection.
