How to retain capture date in and beyond Photoshop?

When I edit an image in Photoshop and save it as a PSD or export it as JPG or TIF, the metadata capture date is removed.

 

Is there any way to have Photoshop retain the capture date? I'm using Windows 10.

    I checked and a JPG, a DNG, and the file from a scanned slide (on which I had manually edited the capture time) all had the capture time (via Properites > Details) before opening with Photoshop but not after saving as PSD or for web. I appreciate the detailed response, Conrad C

    The question JJMack asks is important, because what is normally reported as Capture Time is a specific field embedded by digital cameras. Scanned images typically have only a Creation Date which is the file system creation date, and a completely different field.

     

    Some scanning software such as VueScan may write to EXIF Date Time Original if something’s entered in the Date field in that application. The Capture Time in those should show up properly as if they were taken with a digital camera. If the scanned images don't have an EXIF Date Time Original entry, it’s possible to add one using a utility such as EXIFTool. I haven’t done that before, but it’s something I will look into at some point because I scan lot of film too.

     

    This is a very confusing area because there are multiple fields that can store creation or capture times defined in different ways for different standards.

      Yes,  I have since learned to enter the date taken into VueScan so I don't have to edit the EXIF later.

      But aside from files from scans, the issue still remains given the DNGs and JPGs that have their camera-assigned dates taken lose that data after Photoshop. (In case you missed it, note my post above re: Windows Explorer - Properties > Details)

      Generally, File > Save As should preserve EXIF Date Time Original, while web export options don’t preserve it to save space.

       

      That assumes the capture time is present in the Photoshop document. It should be there if the Photoshop document was created by having Photoshop directly open an original camera raw or JPEG file, but might be missing if the file was already processed or copied/pasted between Photoshop documents.

       

      More specifically, these methods should preserve EXIF Date Time Original:

      • File > Save As > JPEG
      • File > Save As > TIFF
      • File > Save As > Photoshop
      • File > Export > Save for Web (Legacy) with the Metadata option set to All
      • File > Export > Save for Web (Legacy) with the Metadata option set to All Except Camera Info

       

      These JPEG export methods don’t preserve EXIF Date Time Original:

      • File > Export > Export As (any settings)
      • File > Export > Save for Web (Legacy) with the Metadata option set to Copyright and Contact Info
      • File > Export > Save for Web (Legacy) with the Metadata option set to Copyright
      • File > Export > Save for Web (Legacy) with the Metadata option set to None

        In general Expirt Save for web and export will stript Meta data.
