Benro Master Solid Neutral Density filters, available in 4, 6, 8 and 10-stop densities, are essential creative tools for today's photographer. They give you the ability to lengthen exposure times and capture exciting, impactful effects, even in bright light. They also add a silky feel to waterfalls, streams and waves, give an ethereal look to moving clouds and blur other moving subjects, such as vehicle and pedestrian traffic. And they're perfect when you need a slower shutter speed for lens effects such as pans and rotations. All with superior resolution and without a trace of color cast.
