How Does MSM Light Pollution Filter Work？
This light pollution filter is made of a special glass called didymium glass, with multi coating
This filter can significantly reduce the transmission of light from sodium vapor and mercury vapor lamps, which are mainly located in the range from 575nm to 600nm wavelengths, please refer to the chart below. Sodium vapor and mercury vapor lamps, commonly used in street lighting and industrial lighting, emit yellow and orange lights from the ground to the sky, ruining the nightscape views and pictures. So light with wavelengths from 575nm to 600nm is the main cause of light pollution.
This filter is able to greatly block the wavelengths from 575nm to 600nm, helping the camera get the correct color of the night sky and landscape. With the help of the filter, the images with the right color can also save a lot of bother from after-processing.
FAQ
Q:
A:
Q:
Usually using light pollution filters requires about 1 f stop of increased exposure. What is the difference on exposure time when using this filter?
A:
The filter removed the yellow light pollution color cast but the rest of the image wasn't noticeably darker so I would say certainly less than one stop.
Customer Reviews
Didymium Light Pollution Filter
I already received the product. I haven't had a chance to test it. It arrived in perfect condition.
Filtre vraiment efficace et apporte une vrai plus value
Performs well with a stock digital camera in Bortle class 4-6 where I have used it.
Step-up rings can be bought everywhere as well as 82mm lenscap for darkframes and bias. I also got a 82mm metall lenshood on ebay. This will simplify the use of lens warmer/dew heater band.
My filter arrived while I was visiting in Honolulu Hawaii and I used the filter there testing it during the night capturing images overlooking the city from a location called Nuuanu Valley. The sky colors looked much more natural with the filter than without the filter. Amazingly, after I saw the difference, the light pollution became visible to my eyes when I viewed other night scenes. It's well worth owning such a filter. I don't know if Lightroom or Photoshop has settings to even eliminate the light pollution narrow spectrum frequencies of light. I don't know for certain but don't believe you can correct a narrow slice of the light spectrum in post production. And if it can be done, It's labor intensive and has to be done to individual images. Much time is saved using the filter and avoids needless time doing post production corrections. Indoors under flourescent lights the filter gave cleaner whites. That felt like a bonus.
However, to my surprise, the filter did not seem to have any noticeable effect with indoor photographs using a Samsung A12 cell phone camera. I suppose the cell phone adjusted images with and without the filter on.
(of course) easy to use, and provides excellent results.
MSM Rotator
- Overall quality is very good. Yet, MSM may sometimes move in the ballhead plate (vertical mounting) when attached with a heavy lens. I finally need to attach the MSM to a L-bracket first and then attach the L-bracket to the tripod. The L-bracket prevents the MSM rotate.
Filter: used one to two times only. Better to have a narrowband filter instead.
I have tried Hoya and Kenko similar filters, but this works much better. Images are clearer and cheaper too!
I utilized the filter for a few night shots both indoors and outdoors. The difference is shocking. I'd suggest this for any photographer to throw in their bag. There were no signs of vignetting or abberation in the photos. I even used it during shooting of a youtube video that I linked here
Takes up a small space and doesn’t weigh you down! And then it’s simple and easy to set up!
Everything I need. Perfect!
