Take Control of Your Photography-Remotely: Using the included USB or Firewire cable and/or optional WiFi adapters for select models, Nikon Camera Control Pro enables you to capture unique images no matter what the subject. Viewer function: Enables captured images to be viewed within the software. Tone Compensation Curves can be saved in camera: In newer Nikon digital SLRs, including the D2Xs, customized Tone Compensation Curve data can be saved to tailor the camera’s behavior to the photographer’s vision and improve efficiency when using multiple cameras at the same time. Improved graphic user interface: A simulated (camera) LCD panel on the computer screen performs the same function as the camera’s viewfinder display, and has been modified to be consistent with those used in the latest cameras for smoother operation. Compatible with Nikon's Image Authentication Function: Image data can be transferred and stored without affecting the authentication function. Compatible with WiFi operation: In addition to supporting USB cable connections, Camera Control Pro offers compatibility with the optional Wireless Transmitter models WT-2a and WT-3a. When attached to a digital SLR, the WT-2a and WT-3a enable remote shooting and setting via a wireless LAN over WiFi.
