Are you familiar with how Lightroom mobile works together with Lightroom desktop?
If not, are you editing raws or normal image files? In which application did you edit the images?
I am not sure I understand how it works, no. I edited the files on the iPad where they had been imported from the camera's SD card. Upon my return I also imported the images to my computer. Now I would like to apply the same edits I made on the iPad to the versions now found in Lightroom 5 on my Mac.
Hopefully this helps you in assisting me.
Ok, just to make sure that I understand what you are trying to do:
You have already edited the images on the iPad but you have imported the images to your Desktop where the changes aren't visible since you once again took them from the SD card?
As I understand it you have a different copy of the images on your device and the desktop since the edits weren't on the SD card once you imported them to the Desktop.
I still don't know which application you did these changes on the iPad or if your camera takes RAW's or JPG's.
