Light pollution is a real problem, but could things get better for photographers with the Irix Edge Light Pollution filter?
We live in a day and age where electricity rules. This of course is not a bad thing; for one I wouldn’t be here writing this review if it were not for the buzzy stuff flowing through cables everywhere. Electricity also means that we get to turn night to day. Streets are filled with massive glowing buildings, and the roads are lined with lights that allow us to see in the dark, but the city lights (sodium lamps in particular) are polluting the night sky. The yellow glow they give off, and the haze they produce can be seen for miles and miles in all directions. Not only can this have a negative effect on night time cityscapes, the glow can also hamper efforts to capture the night sky, even if you think you’re far enough away from them, the glow will still affect your images.
This is where a product like the Irix Edge Light Pollution filter comes in. The premise is simple. Make a filter that can attempt to block out the sodium lamp spectrum (589nm) so that photographers can take shots at night that will not have a yellow color cast, nor haze that is produced by city lights. The question though is, can this filter do the job?
