Extensis today announced the immediate availability of the Pro Photo Raw Image Filter for Portfolio 6, its award-winning Digital Asset Management (DAM) solution. The new filter allows professional photographers to preview, sort, and archive Raw image files from leading digital SLR cameras without having to first convert them into another format. Registered owners of Portfolio 6 are eligible to receive the Raw image filter by updating their current version of Portfolio to 6.0.1 for Mac OS 9 or 6.1.2 for OS X.
