How to Change image captured date in python?

Question

I have over 500 images (png /jpg) having wrong captured date (Date taken) because of wrong camera date settings. I moved photos to mobile and mobile gallery sorts photos on the basis of 'Date Taken'. I want all photos to be displayed in order.

So how can I change captured date (Date taken) using python script?

Answer 1

This is quite easy to do using the piexif library:

from datetime import datetime
import piexif

filename = 'image.jpg'
exif_dict = piexif.load(filename)
new_date = datetime(2018, 1, 1, 0, 0, 0).strftime("%Y:%m:%d %H:%M:%S")
exif_dict['0th'][piexif.ImageIFD.DateTime] = new_date
exif_dict['Exif'][piexif.ExifIFD.DateTimeOriginal] = new_date
exif_dict['Exif'][piexif.ExifIFD.DateTimeDigitized] = new_date
exif_bytes = piexif.dump(exif_dict)
piexif.insert(exif_bytes, filename)

This script will insert the new date 2018:01:01 00:00:00 into the DateTime, DateTimeOriginal and DateTimeDigitized EXIF fields for image.jpg.

No real need to write Python, you can do it in one line in the Terminal using jhead. For example, adjust all EXIF times forward by 1 hour

jhead -ta+1:00 *.jpg

Make a COPY of your files and test it out on that first!
