Natural Night
The distinct filter is designed to block the wavelengths of light created by mercury vapour, sodium and other Low CRI lights that are often used as streetlights. These lights are usually yellow/orange and are the primary cause of light pollution around cities. This makes capturing beautiful nightscapes near cities very difficult.
Keep far away from light pollution when enjoying the wonderful night
As you can see there is a significant difference in the yellow cast caused by the lights of the city. You also have an increase in the contrast of the image, especially in the areas that were washed out by strong nearby street lights. But you will also notice that you have a more magenta sky. Personally, I prefer the magenta sky over the yellow/green sky. But that is also an easy adjustment in post-processing.
