Ominesence: the state or quality of being ominous. The real word is ominousness, but I made up this alternate. This is a river and city with dark clouds overhead. The right side is bright light and good weather, though it too is broached by darkness. I took this in a moving car crossing a bridge; you can see the railing at the bottom. Used a 1/250 second shutter speed to freeze the scene, though I had to go up to ISO800 because it was so dark out.
I added contrast, darkened the dark clouds and corners, and removed a lot of noise. There were lots of markers and pylons in the river which were bugging me. I cloned all of them out. Now it looks like it should.
