问题
Recently used Google Takeout to download 60GB+ of photos and video from Google+.
This has resulted in plenty of files -- but valuable metadata including the original dates for photos and often location is stored in a separate metadata.json file for every album, instead of in EXIF.
This means I can't import it to any other photo service without essentially scrambling all the dates based on what G+ made automatic edits to the photos.
Can't find an answer anywhere -- solving this should help anyone out who is hoping to move their photos from Google's service elsewhere.
回答1:
There is a Exif tool out there from http://www.sno.phy.queensu.ca/~phil/exiftool/
Plenty of docs there, but some examples:
called like this
exiftool -json=picture.json picture.jpg
or
exiftool -filename -imagesize -exif:fnumber -xmp:all image.jpg
