Neutral Density Filters

Check it out! I told you I’d get around to writing about the new ND filter. ND stands for neutral density and comes in varying grades varying from 1 to 8. Mine is an ND 8 by a company called Tian Ya. Yes it is from Hong Kong and isn’t a well known brand like Cokin or Hoya, But those were $40 and mine was $12. But does it work!??! That is indeed the most important thing. Below are two pictures, both done on manual with settings of f/22 1/8s shutter speed an ISO value of 100. The first is without the filter and the second is with.

As you can see, the filter allows you to capture bright details with a slower shutter speed, so if you wanted the clouds streaking across the sky, this is the filter for you. Obviously the trees in the shot are under exposed and you could achieve the same look in the picture I have shown by using a faster shutter speed, but that’s not the point I was trying to make. I just wanted to show the amount of light it blocks out. It’s kind of like sunglasses for your lens! And it goes on just as easy, just screw it into your lenses existing threading. The one that I got has threading on both sides so I can screw on my macro or wide angle lenses on top of the ND filter, or another ND filter on top to make it an ND 16!!!


  1. The biggest use I have out of my UV filter is to protect the lens. :) I know you were probably showing the filter differences but the first shot is a little overexposed. Would love to see a comparison with a proper exposed shot and the diff. with the filter. Nice review and would love to read more!

  2. I'd get a UV filter to protect my lens but I just don't have the money right now. Down the line I'm gonna have all kinds of neat filters and lenses, but for now I'm just using the ND filter to do long exposures while the sun is still up.
