    Is it possible to change metadata on an exported photo?

    Lichtzeichenanlage Community Member

      Hi,

       

      I want to change the metadata of an exported photo without manipulating the original photo. How can I do this

          There are plenty of tools to do that, some free some for small fee.  Exiftool is a free tool that probably will do the trick on a one-off basis.  If you plan on doing this on many images, or if this is a common thing you wish to do, you might want to consider a browser program that can batch change certain metadata such as the free browser like Microsoft Pro Photo Tools v2.  There are others as well.

           

          If you are exporting images that intend to always add additional metadata to the original on export, you might need to have a simple export filter written using the SDK, geared towards your specific situation.

            unless this is the sdk section of the forum, I think about a developed solution and not for some tools.

            No. I do not want to add or manipulate data to the original photo. I just want to apply metadata presets to the exported photo.

             

            A post processing filter was my first thougt, but I need to have a photo object which is not available at that point

              Indeed this is the SDK section of the forum, but that's OK.

              Maybe a workaround would be:

               

              a.     Create a simple collection of images you are in need of exporting with the special export metadata,

              b.     Select this collection, then all the images in the collection;

              c.     Create a virtual copy of the images in the collection, then filter for only VCs in the collection;

              d.     Apply the special export only metadata and export the VCs as you normally would export the images;

              e.     Once the export process is complete, delete the VCs to avoid future confusion.

               

              Not a great approach but something like that should get you where you want to be on this issue. An export filter applied after the JPEG is generated would accomplish the same thing but then it would require significant programming and doesn't allow you as much flexibility.

               

              Good Luck!

                Collection preseter may help(?)

                 

                If you are willing to export back to the catalog, and you can define collections which take different metadata presets, the collection preseter will apply them automatically.

                 

                There is no facility to apply just to selected photos, yet, so the presets will be applied to all photos in the specified collections.

                  it is really important to do that metadata stuff within the export session. As mentioned before I could use a export filter. To generate a photo object i could add it to the catalog. But then I have to problem about deleting the stuff.. grr

                    Since you are a plugin writer, how about writing that export-filter - seems like a good idea.

                      Because it is a pain to add the photo to the catalog and not be able to delete it...

                        If its an export filter, you don't have to add it to the catalog and delete it - that's the beauty of export filters: they apply to the exported photo on the way out the door...

                          Perhaps I haven't understood the concept of the export filter. But if I understod it right I just have access the original photo as a LrPhot and to the exported photo as a path. So - if I want to apply metadata to the exported photo without manipulating the original photo I have to convert the path into a lrphoto object. And therfore I have to add it to the catalog.

                            I see where the confusion lies.

                             

                            If you want to assign a metadata preset then the photo has to be in the catalog.

                             

                            The export filter would allow you to wire-up exiftool to the photopath not in the catalog.

                             

                            However, you can easily convert metadata presets for use with exiftool just be dofile-ing them, at which point the preset values will be in _G.s

                             

                            I'm not sayin' it ain't a bit of work, but this the SDK forum, after all...
