It seems that all is not well with Windows Vista and metadata produced by digital cameras. CNET are reporting that if you edit a photo’s metadata through Vista or Microsoft Photo Info, then your digicam’s software may no longer recognise the metadata, or even worse, the photo itself. So far, Nikon, Sony and Olympus have issued Vista RAW codecs to solve this issue. I’m still using good old Windows XP, so have you installed Vista and ran across this problem?
