When you think of ND filters, you probably think of 3-stop or 6-stop filters or maybe even a 10-stop if you really want to go extreme. But what about a 16-stop filter? This fun video shows what it's like working with such an insane filter.
Coming to you from Anthony Morganti, this fun video follows him as he shoots with a Formatt Hitech 77mm Firecrest ND 4.8 filter, which reduces exposure by a crazy 16 stops. For those of you interested in the math, that's a factor of 2^16=65,536. In other words, a normal 1/200 s daytime exposure will become an astounding 328 s (5.5 minutes) with the filter attached. For reference, even a relatively extreme 10-stop ND filter would only turn that exposure into one just a smidgen longer than 5 seconds. Of course, with a piece of glass that is practically black attached, focusing is pretty much impossible, so it's best to pre-focus, then attach the filter. And furthermore, it's definitely overkill in a lot of situations, but that's half the fun of playing with it, and depending on the situation, you can create some truly unique images and turn just about any turbulent body of water or sky into silky smooth flows. Check out the video above to see what it's like using it.
