Blackstone ND filters are available in 3, 6 and 10 stop densities.

• Blackstone ND 3 Stops is excellent for making aperture adjustments to give you that shallow depth of field look, or to make longer exposures during sunrise or sunset and in shaded areas.

• Blackstone ND 6 Stops is an excellent all around filter for landscape photographers. It's just dense enough to give a pleasant long exposure effect in just about any conditions.

• Blackstone ND 10 Stops is a true long exposure filter that allows the photographer to capture misty water, ethereal clouds, and to effectively blur-out people from crowded urban areas.

  
  

  Blackstone ND Features

  Technology

  
  
  The technology used to create Blackstone ND is revolutionary, and features a new 22 layer double-sided coating process that is perfectly neutral with no color shift, has zero loss of resolution and detail, has the best anti-reflective qualities of any ND on the market, and is both hydrophobic and oleophobic (meaning it sheds both water and oil). Blackstone 13 & 16 stop long exposure filters feature a full 28 layer coating.
  
  

  100% Neutral. 100% Resolution.

  
  
  Blackstone ND filters are a technological leap-frog advancement over competing ND filters. Legacy dye-based ND filters suffer from serious color cast. The first generation of Vapor Deposition Coated (VDC) ND filters have largely corrected the color cast problem, but lack the ability to resolve high-megapixel camera without diffusing the image. Wine Country Camera’s exclusive Blackstone ND features the next generation of vapor deposition coating that is both perfectly neutral across all spectrums of light (including UV and IR) and resolves the image with zero diffusion effect.
