It's the plug-in everyone wanted...
Telling us virtually everything we needed to know is the accompanying Microsoft blurb:
"This is the HD Photo file format plug-in for Adobe Photoshop software. The HD Photo plug-in supports a wide range of pixel formats (including high dynamic range, wide gamut formats) and numerous advanced HD Photo features. This plug-in is designed for use with the CS2 or CS3 versions of Adobe Photoshop software running under Microsoft Windows XP or Microsoft Windows Vista. Any other use is not supported."
HD Photo files created on both Mac and PC have identical features and are fully compatible with each other working with Vista, Windows Live Photo Gallery, the HD Photo Device Porting Kit and now Photoshop.
Beta versions of these plug-ins had been available but given they have a 31 December expiration dates the final edition is extremely welcome.
Don't expect HD Photo to catch on for another 12 months but with better image quality provided at vastly improved compression rates and needlessly high eight and 10 megapixel fashion cameras proliferating the market, arguably we could do with its widespread adoption sooner rather than later...
