What do we use a StarScape Filter for?
When and on which occasion do we need to use Marumi StarScape filter?

The Star Scape filter cuts light pollution off caused by artificial light sources in order to capture the true beauty of the starry sky.

 

What is "Light Pollution"?

Light pollution refers to artificial light sources such as;
- mercury lamps,
- sodium lamps,
- LEDs,
- fluorescent lamps,
- or Automobile headlights that brighten the night sky and make it difficult to see stars.

In modern inhabited areas, it is hard to see the Milky Way in urban cities, and when you actually take a picture, the night skyscape sometimes turns obviously yellowish. This color shift phenomenon is caused by, so to say, "Light Pollution".
This color shift makes the starscape-/nightscape photograph enthusiasts very annoyed. 

How Marumi StarScape eliminates Light pollution?

By kneading a component that absorbs unwanted light into the glass, the color shift phenomenon will be suppressed, turning the overall image natural bluish.
In addition, no matter which white balance is selected, there is no extreme color shift.

The brightness, which is a significant element for starscape photography, can be sufficiently secured at an exposure multiplier 1.2 (about 1/4 stop).

 

The StarScape filter is also available in screw-in filter.
