Nikon's U.S. and European technical support websites have both posted 30-day trial versions of Camera Control Pro for Windows and Mac OS. Camera Control Pro is Nikon's new standalone application for wired and wireless remote operation of Nikon cameras.
An earlier story on this site has a little more detail on this software.
On the Nikon USA site, see these pages for the Windows and Mac versions.
On the Nikon Europe site, see these pages for the Windows and Mac versions.
A full license, which won't be available for sale until later this month, will cost US$79.95 from the Nikon USA Mall.
