Water Tower

Adjusted levels, added minor vignetting, removed some desaturation...

It's still to dark. Saturation shouldn't be lowered, it's exactly the rust that gives this image character, that B&W version is just a conformation of this. I would certainly add some sharpening and inject a tiny bit of blue in the background. In this example I have done all that, including a crop at top and bottom and a correction to get more details in the shadows.
