Publisher review:ViewNX 2 is an OS X image browsing and editing application for photographs and video files.
ViewNX 2 provides a range of easy-to-use, enjoyable features that the ordinary software supplied with a PC's OS cannot offer. In addition to basic data importing and browsing, ViewNX 2 incorporates various frequently used adjust menus and tools such as resize, brightness control, crop and straighten, as well as RAW processing functions and movie-editing features that are equivalent to those found in digital SLRs. Smoother cooperation with Nikon's exclusive image storage and sharing site, my Picturetown, is also made possible. This all-in-one browsing/editing software package supplied with Nikon digital cameras will let more photographers fully enjoy digital images, more easily.
