    Lightroom export Date Taken


      When I export to JPG from LR 2015, I'm finding that the Date Taken (or whatever EXIF calls it) is not written to the file although the Create Date and Modify Date (dates of export) are included in the JPG file. So if a photo was taken on 2016-10-22 but not exported until 2016-11-05, I see only the November dates when searching the binary JPG data with a hex editor.


      The Date Taken is VERY important to me because I can see the WHAT of an image by its thumbnail in Windows Explorer, but I want to know the WHEN. I don't want to have folders like "Vacation 2007", "Vacation 2008, "Christmas 2009", etc. because all the year's photos I take in any given year go into a single folder called "2011", for example. That way, even if I don't remember the year, at least I can say, "That was the summer of 2007 or 2008." and still find the image I'm after with relative ease.


      So, as a software developer, I created a small program to rename DSC_3005.JPG to something like 2016-10-22 21.45.16.JPG in YYYY-MM-DD hh24.mm.ss format. This is done recursively through a directory tree in every version of Windows in existence since 2004.


      If LR doesn't output the Date Taken to the JPG file like Photoshop 2017 does so that I can run all the JPG files through my app, then LR is pretty much useless to me as an export tool. It's nice to name catalogs and libraries where I can flag and label photos, but not at the expense of losing Date Taken information during exports.


      Does anyone know how LR can export that info (I have "All Metadata" checked in the Export options) or do I have to do all my exports in Photoshop? Surely, Adobe can't be this clueless as to not include a piece of metadata that might be VERY IMPORTANT to some photographers!

          LR does indeed export the capture date to the EXIF:DateTimeOriginal field. You can verify that by reimporting the exported photo into the LR catalog, by viewing the file's metadata with Exiftool or other metadata tools, or viewing the Date Taken column in Windows File Explorer.


          If those methods aren't showing the capture

          date in the exported file, we'll need more details.

            I think I may have come across a bug in LR, but so far I haven't been able to replicate it.


            I started out importing 1268 raw images taken with 2 Nikon D810s and a Sony a6000. There was no chance of filename conflicts because of file name extensions (ARW, NEF) and sRGB vs Adobe RGB on the Nikons. Then over the course of 3 weeks, I edited the files very much in a random order, starting with easy edits and progressing to harder ones. I started with basic things like Auto WB and exposure with some sharpening and noise reduction where it was needed and cropping the images as I wanted. The images I was going to export as 8x10 I put into the Quick Collection, others where 8x10 wasn't feasible were rated 5 stars, and still others that I wasn't going to edit yet but still might keep given a red label. I then filtered on the QC, selected them all, and exported to a specific folder (asking what to do with existing files), using the same filename with an uppercase extension and 3000 pixels at 300 PPI along the long edge. I then marked them as rejected ("disabled" thumbnail as a quick way to see it had been processed) and cleared the QC. I did the same with the other categories, choosing a different folder and long edge pixel count of 5400 for the "unfeasible" 8x10s, or unchecked "Resize to Fit" and yet another folder for the unedited ones. All other export options remained the same. After each export, the filtered photos were rejected and the attribute removed. In each of those exports, it was highly likely that images from all three cameras could appear in the filtered set. I ended up with 960 images in the final catalog where the other 308 were removed from the catalog and deleted off the disk because there was no chance they were going to be used.


            So today, I selected a few of the rejected 8x10s, exported them, and lo and behold, the Date Taken appeared in the Properties box for each file in Windows File Explorer! I thought perhaps the checked items in the Metadata section might be the issue or perhaps a different destination folder I used for my testing but nothing manifested the issue I initially found. Believe me, I would have never submitted this issue if the dozens of files properties I looked at all didn't have a missing Date Taken.


            I'm going to try the export again, except this time I'll be choosing the files for an entire category so there's pretty much a guarantee that each one will have images from multiple cameras, different export location, and different sizing options. The hard part will be ensuring I select ALL the files in each category from the 960 before doing an export.


            If I come across this issue again during those exports, I'll let you know and if it still exists for my "unique" circumstances, perhaps you can let me know some things to try to help isolate the problem. If all goes well, I'll let you know that, too.
