The Hitech 3.0 Neutral Density PROSTOP 10 Stop Filter for Lee Holder has been designed for use on long exposures allowing use of much slower shutter speeds. The visible effects created by using longer exposures is the effect of motion blur on any movement within your pictures, such as clouds, waterfalls, seas and rivers. The PROSTOP filter is fitted with a foam gasket perimeter, which creates a seal between the filter holder and lens, thus reducing light spillage around the sides of the filter.

10 stops is alot. Be careful! But if you need alot of motion blur in your photos, this is it!
Fun to use for long exposure effects. There's a strong color cast, but it's correctable in post if you use a WhiBal card. Bought this instead of the Lee Big Stopper for two reasons: availability and the fact that this is made of resin rather than the delicate glass of the Lee. More than happy with my decision.
This filter gives an odd color cast that I could not remove to my satisfaction with my professional digital software. I do not recommend this filter.
