Koblenz is a beautiful city located at the confluence of the busy Rhein and Mosel (meandering its way from France). This region is famed for its exquisite wines and fresh fish from the many fish farms in the locality. This photo is taken from the promenade leading to 'Deutscher Eck'. There is a cable car which takes one to Ehrenbreitstein fort (seen in the pic) across the Rhein. I used a graduated CPL filter and slightly negative exposure to bring out the texture in the clouds. In the process I lost a bit of colour, which I do not mind in this case as my primary intention was to capture the beautiful clouds against a nice foreground.
