Title: Missing exif info on apple X photos
Post by: masteroffnone on December 04, 2020, 02:56:50 PM
I have many Iphone 10 photos with missing correct exif creation date. For example this photo was taken on 2020:7:29 (Looking in my agenda, it was an import event).

What am I doing wrong? I'd like to organize my photos in <year><month><day> folders and this leads me to issues.

I'm starting the think it might has to do something with dropbox. I have been uploading some of my photos automatically to dropbox.

Looks like i use .heic originally and when uploading to dropbox it gets to .jpg and removing some exif data  :(

All I can say is that this definitely isn't an original iPhone JPG image.

That seems to be a very strange for Dropbox to be changing the format of the image, but it looks like it's an option.  See here (https://help.dropbox.com/installs-integrations/mobile/ios-formats).

Have you checked to see if the originals are still on the phone?

Otherwise, there isn't any time data in the file to fix it with and the filename isn't a timestamp.

After testing with one photo with dropbox camera upload (iphone X to dropbox) it does not indicate it's changing the EXIF data. Thats the good news. Have to look further what has gone wrong in my setup..
