Going to the Dark side

Hoya ND x400

A last minute addition to the camera collection for the trip is the Hoya ND x400. See the pic above? Yes, it really is that dark. This thing reduces light values by 9 stops to less than 1/500th of its original intensity!

In most situations, you cannot even auto focus with this filter attached. You have to take the filter off, focus and compose your shot, lock in your settings, put the filter back on, and then do a few quick calculations for your new exposure values using your original (w/o filter) values.

Seems like a lot of work, right?! Yes, but this filter also allows you to get shots that would be virtually impossible without it.

Super long exposures in the daylight is one example. And, if used correctly, you can literally render moving objects invisible! Pretty neat.

Can’t wait get some test shots with this filter.
