Comments about B + W B + W 72mm #106 1.8 (64X) Neutral Density Glass Filter:

Great filter

Both pictures where taken at Great Fall of the Potamac park in VA on a cold, sunny day in January. A tri-pod was used for both photos.

Picture #1 - "Milky" Water Fall
F/22, 64X ND Filter - the resultant shutter speed was 1 sec. (Olympus E-520, Zuiko 12-60 SWD lens, 30 mm focal length)

Picture #2 - "Fast" Water Fall
F/4, UV Filter, the resultant shutter speed was 1/2500 sec. (Olympus E-520, Zuiko 12-60 SWD lens, 60 mm focal length)

Botton line, I'm glas I purchased the 64X, in birght sun on a reflective surface it took all of the 64X filter and a complete stop-down of the apperature to slow the shutter speed to something acceptable for a "milky" look.
