Nik Software announces today 64-bit compatibility for its digital image processing tools. Current owners of Nik Software's products can upgrade for free to 64-bit compatible versions. Owners of Dfine 2.0, Viveza 2, Color Efex Pro 3.0, Silver Efex Pro and Sharpener Pro 3.0 plugins for Lightroom, Aperture or Photoshop CS5 can find upgrades here.
A mainstay of Nik Software's products is "U Point Technology," a tool that allows users to apply changes to a photo locally without using layers. More information about this and other Nik Software features is available at their website.
