Here is a short article on how I post processed this picture. I took this picture a few days ago from the second floor of a building in Brugge. You can see the Grote markt (central square) with the Christmas market. This picture comes from a timelapse I made for Christmas.
The sky is created with 100 pictures to simulate a long exposure effect. I use the jpeg I exported for the timelapse. I opened all of them in a single Photoshop document (files< scripts<load files into stack). I created a smart object by selecting all the pictures, right clicking < create smart object. I use mean mode to create the long exposure (layers<smart object<stack mode<mean).

After, I used to other exposure, one with the horses and one with the peoples on the left. I blended them with the sky. I added an orton effect, some warm light in the sky and on the horses.
Here is the before/after. Such a huge difference ! You probably notice that the before image was quite under exposed. I made that choice on purpose since it is easy to bring back details in the shadows than in the highlights.
