Does this thing really work? How many Stops ...
Does this thing really work? How many Stops should I anticipate opening up? Do I compose without the filter then screw it on the lens?
I have had no success with this filter. Regardless of Aperture, Exposure time, and ISO in broad mid-day full sun - I still get a black photo.
