I need help understanding a couple of fundamentals of how GPS coordinates are written to EXIF in LR4.
Here's the bottom line: I understand how to insert coordinates into a photo's EXIF. I can clearly see the coordinates when viewing EXIF within LR4, but that's where the trail ends.
I am trying to view the GPS EXIF data in multiple other programs and I just don't see it anywhere. I also participate in an web sharing site that automatically maps photos upon upload, assuming the coordinates are in the EXIF. This isn't working for me either. As a test I uploaded a file that had coordinates written to EXIF (according to LR4), and then downloaded that image back to my PC, and re-imported it to LR4 ... I can see all EXIF except no GPS coordinates.
For all practical purposes, it appears LR4 is not really writing the coordinates to EXIF except for what is displayed inside the shell of Lightroom.
What am I missing?
I have done very little with GPS. But a couple of questions:
Are you writing changes to XMP in your Lightroom preferences?
Are you looking at exported images, or just the images that you modified using Lightroom?
Thank you for trying to help.
1) I was not familiar with writing XMP changes. I just looked at my catalogue settings and I see that feature is NOT enabled.
2) Well, some of them were previously exported images. I wrote GPS coordinates to a large selection of photos which were a mix of RAWs, TIFFs, and JPGs. I didn't "re-export" any of these files after inserting the coordinates. I honestly assumed that if I inserted coordinates into the EXIF in LR that it became an intergral part of that file data, regardless of which application it was viewed in after making the change.
JimHess, Okay, you've helped lead me to the answer, and I appreciate that!
I'll handle these metadata manually as described here: http://help.adobe.com/en_US/Lightroom/3.0/Using/WS638E3AC9-A04C-4445-A 0D3-F7D8BA5CDE37.html
Thank you very much!
