This is a old oil tank in an oil refinery that doesn't exist anymore. Just a few dilapidated buildings and foundations are left. There must have been a serious oil leak or something. A lot of things a cake with a dark tar-like substance. It hasn't been used for a long time.
I developed it in Lightroom and Color Efex Pro4. I used Skylight Filter, Contrast Only, Graduated ND, Remove Color Cast.
