I used Lightroom to rename a bunch of Nikon D3 JPEG files, and now much of the EXIF data in these JPEGs has disappeared. Critical parameters like exposure, exposure bias, focal length and date and time, as well as less critical parameters like file size and dimensions, now have the value <mixed>. All of these EXIF parameters had the correct values prior to the renaming. Has anyone seen this before, and is there any way to get the EXIF back?
I'm running Lightroom version 1.3 on a MacPro with MacOS 10.4.7.
EDIT: Quick follow-up. I opened a few of the JPEGs in Apple's Preview app and used the Get Info command to look at EXIF. It appears all of the EXIF is still there. It's just not showing correctly in Lightroom's Library module.
EDIT: OK, another quick follow-up. The EXIF only appears to display incorrectly in grid view within the Library module. When I double click a thumbnail to get the Loupe view, the EXIF displays correctly. I'd still like to get to the bottom of the problem in Grid view, just in case it's indicative of a larger problem that might bite me in the future.
