Photographing solar eclipses and ultra-bright light sources can be extremely dangerous. This filter reduces light values by 9 stops to less than 1/500th of its original intensity and allows safe photography. It can also be used to achieve super slow shutter speeds in daylight to render moving subjects invisible, and will enable you to use slow shutter speeds, especially with high speed films, to record movement in subjects such as waterfalls, clouds, vehicles, etc. It will also decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background. And this filter allows you to decrease the effective ISO of high speed film (above ISO 400) so it can be used outdoors in bright situations. Neutral Density filters have no effect on color balance, appear grey and reduce the amount of light reaching the film. Multi-coating minimizes reflection at the filter surfaces which reduces flare as well as ghosting.

The attached picture was taken with a Nikon D5000--f/18, ISO 100 and 46 second exposure. This was my first time using it. I love the quality of the Hoya filters.
(Beware of Seller changes, that's when you can get burned!!!)
:: PROS ::
1.) Well made in Japan.
2.) They feel like good optical glass.
3.) Great for beach, lakes, and stream long exposures!
4.) Threads are machined exactly to specs, least mine was ;)
:: CONS ::
1.) Nothing so far, I need to use them more to be honest.
:: OVERALL :: Good optical glass from Japan, is it like the old school quality, maybe not. I do like them I have used them a little, looking forward to taking some shore long exposures to post for you later. I like it better then my TIFFEN version.
