JPG's AND the original CR2's (from a Canon 5D Mk1 and a 1DS Mk III)
I have CR2's that were ingested and 'saved as' using 4.6 RELEASE, so I know the info is there, but when I click on the little 'i' icon in contact sheet view, all the IPTC fields are blank. Opening the images in photoshop shows the info is still in the files, but just not displayed in 4.6.1 beta 6 (haven't tried beta earlier than 6)
I only installed the beta 6 at the weekend, so I know all the IPTC info was in the files before hand.. I've gone back to the release version now, and while files ingested using beta 6 have no IPTC info, the files created from the release version now show the IPTC info again.. so it's definitely something in the latest beta(s).
