It only checks IPTC:Caption-Abstract and XMP:Description, in that order.Įditing the data online, then downloading the image does not seem to change the metadata that was originally uploaded.Īctually, I typed too soon - I thought making the update got google photos to recognize the proper date/time, but it still did not.

Google Photos seems to ignore everything else except a description. IPTC:DateCreated + IPTC:TimeCreated are not set as often in most pictures straight out of a camera in my experience.Įdit: Checking for other metadata. Personally, I would suggest making sure that EXIF:DateTimeOriginal is set properly as that is a better standard in my opinion. So, the file was set to 12:20 and changed it to 15:20. My computer's current timezone is -7 hours, but Google Photos set it to -4 hours and adjusted the time. This one was odd, as it was different than the gps timezone modifier. System:FileModifyDate +Timezone modifier. GPS:GPSDateStamp + GPS:GPSTimeStamp + TimeZone Modifier (-6 hours in my test)

Here are the results from highest priority to lowest. I did some testing to try and figure out the priority of which metadata Google Photos uses as the date for images.
