Nikon offers a new IPTC Preset Manager software for Nikon D4 which requires Microsoft Silverlight. The software lets you enter IPTC presets for cameras (D4) that embed International Press Telecommunications Council information. NikonWeb offers a simple alternative program that can be downloaded for free here (Windows only):
“This small, stand-alone Windows program consists of a single executable (.exe) file, and does not require any admin rights or other special privileges. You can run it from a USB stick or even your memory card. It will not alter your system in any way. Files created with this program are identical to those created by Nikon’s own IPTC Preset Manager (ver 1.0).”
