Astroklar Light Pollution Filters – Clearing up the night sky

It’s a well-known, but painful, part of modern life – Light Pollution.

Our cities a pumping out more and more artificial light every year, and while efforts are being made to reduce the impact on the environment, our night skies continue to suffer.

The yellow-orange glow from our streetlights and city illuminations can cause both a distraction to the environment that we’re trying to capture in a photograph, as well as reducing our ability to see the sky and stars above.

For many years, the only solution has been to avoid the cities – get away from all of the artificial light and shoot in a “dark sky” area.  That’s a great theory, but what if the subject of our shot isn’t in such an area?

Rollei now has a solution: The Astroklar filter.

Available in both square and round screw-in formats, the special filter coating actively cuts those distracting yellow-orange wavelengths of light, reduces the green light that enters the lens, and minimises infra-red transmission – all while retaining image fidelity across the other wavelengths during capture.

The result?

More clarity, more contrast, less artificial yellow tones to your images – but most importantly, a reduction in the polluting light that affects our view of the sky above.

Further from the city lights, we can see more detail in the night sky by nature of our distance, but the clarity in the sky above is really enhanced by the addition of this special piece of glass.

What about when we’re in a dark sky region? We’re not trying to “cut” light pollution – there’s not much to start with, anyway!

But we can make use of its ability to improve clarity, and reduce the yellow tones across the image to enhance the show that’s being put on in the sky above…

When using the Astroklar filter, you must bear in mind that the overall effect it has on the image is to “cool” it down by 500-700K.  So, if shooting at 3000K normally, you may need to manually adjust your white balance to around 3500-3700K when adding the Astroklar filter to your shot – that way, you can be sure the scene remains faithful to the image you saw with your eyes.

So is Astroklar only for the night sky? Absolutely not!

Astroklar certainly helps cut light pollution in areas where it’s not wanted – but it also helps to enhance the city lights themselves. Scenes become more vibrant, higher contrast, more vivid overall – without the stale look of a yellow/orange artificial glow that often surrounds the sky above.

So there we have it – If you’re shooting at night, and capturing the finer details in either the stars above or the cities below, Astroklar can help make your image stand out from all the rest.

…and isn’t that what we’re all aiming for when we capture a stunning scene?
