[This post contains formatting and embedded images that don't appear in email. View the post in your Web browser.] Which plugin produced the DNG? It appears that both the plugin and LR are not following the standards correctly. A workaround: After importing one or more DNGs from the plugin, select them and do Metadata > Edit Capture Time. Then click Change All. This will not, will not, will not, repeat WILL NOT set all the photos capture dates to the same date/time. The photos will retain their respective capture date/times. (Sorry for the redundant repetitive repetitions, but many people have ignored what I've written about this in the past.) Gory Details The DNG contains these relevant date fields: [EXIF] Date/Time Original : 2024:02:18 11:07:52
[EXIF] Create Date : 2024:02:18 11:07:52
[XMP] Date Created : 2024:02:18
[XMP] Create Date : 2024:02:18 11:07:52+01:00 The standards define these meanings: EXIF:DateTimeOriginal -- when the shutter was pressed EXIF:CreateDate -- when the image was digitized (which will be different from DateTimeOriginal in scans of analog images) XMP:DateCreated -- when the shutter was pressed XMP:CreateDate -- when the image was digitized (Shame on the industry for such confusing names.) So EXIF:DateTimeOriginal and XMP:DateCreated should be the same, but in the DNG, XMP:DateCreated is missing the time. That appears to be the fault of the plugin. When LR imports the DNG, it uses EXIF:DateTimeOriginal in preference over XMP:DateCreated as its notion of Capture Time, as recommended by the Metadata Working Group standard that LR follows. This is the date/time LR displays under the thumbnails and in the Metadata Panel's Capture Date/Time. But when LR exports the DNG as a JPEG, it fails to include EXIF:DateTimeOriginal, though the Metadata Working Group says it should. It just includes XMP:DateCreated, which is missing the time due to the plugin bug. So when you reimport the JPEG into LR, it uses XMP:DateCreated as the capture date, which is missing the time. The workaround, invoking Metadata > Edit Capture Time, often fixes such LR date/time inconsistencies in the LR catalog. While LR's failure to include EXIF:DateTimeOriginal in the exported JPEG is a bug, I don't think it's worthwhile filing a formal bug report. There are much more common bugs in LR's handling of capture dates that haven't been fixed for over 15 years, so no point in wasting time in filing a bug report about an issue whose root cause is a buggy plugin.
