|SOLVED] Glob JPGs, read EXIF, update file timestamp?

[Winfried]

Hello,

My digital camera has no GPS, so I sometimes take pictures with my smartphone when I need to get geotagged pics.

Problem is, I noticed the time on the camera on my last trip was about 1h ahead than the time on the smartphone which is correct since set from the GSM network.

So, to make it easier to create a slideshow, I need to write a Python script to update the file time on all the pics that were taken with the camera, and substract 1h so they're about the right time.

Pseudo-code:

Glog *.jpg including subdirs
	Read EXIF
	If no GPX //Camera, not smartphone
		Substract one hour
		Update timestamp

Would someone have some code to share?

Thank you.

Edit: Almost there:

#pip install pathlib
from pathlib import Path
#pip install exifread
import exifread, sys

for mypath in Path('c:/my/path/').rglob('*.jpg'):
	p = Path(mypath)
	p = p.resolve()
	with open(p, 'rb') as f:
		tags = exifread.process_file(f)
		if "GPS GPSLatitude" in tags:
			print("GPS: ", p)
		else:
			print("NO GPS")
