For Python3 x and starting Pillow  6 0 0  Image objects now provide a getexif   method that returns a  lt class  PIL Image Exif  gt  instance or None if the image has no EXIF data  From Pillow 6 0 0 release notes   getexif   has been added  which returns an Exif instance  Values can be retrieved and set like a dictionary  When saving JPEG  PNG or WEBP  the instance can be passed as an exif argument to include any changes in the output image   As stated  you can iterate over the key-value pairs of the Exif instance like a regular dictionary  The keys are 16-bit integers that can be mapped to their string names using the ExifTags TAGS module  from PIL import Image  ExifTags  img   Image open  quot sample jpg quot   img exif   img getexif   print type img exif      lt class  PIL Image Exif  gt   if img exif is None      print  Sorry  image has no exif data    else      for key  val in img exif items            if key in ExifTags TAGS              print f  ExifTags TAGS key    val                  ExifVersion b 0230                                  FocalLength  2300  100                ColorSpace 1                                 Model  X-T2                Make  FUJIFILM                LensSpecification  18 0  55 0  2 8  4 0                                  DateTime  2019 12 01 21 30 07                     Tested with Python 3 8 8 and Pillow  8 1 0

I have found that using   getexif doesn t work in higher python versions  moreover  it is a protected class and one should avoid using it if possible  After digging around the debugger this is what I found to be the best way to get the EXIF data for an image   from PIL import Image  def get exif path       return Image open path  info  parsed exif     This returns a dictionary of all the EXIF data of an image   Note  For Python3 x use Pillow instead of PIL

You can use the  getexif   protected method of a PIL Image  import PIL Image img   PIL Image open  img jpg   exif data   img  getexif    This should give you a dictionary indexed by EXIF numeric tags   If you want the dictionary indexed by the actual EXIF tag name strings  try something like  import PIL ExifTags exif         PIL ExifTags TAGS k   v     for k  v in img  getexif   items       if k in PIL ExifTags TAGS

You can also use the ExifRead module   import exifread   Open image file for reading  binary mode  f   open path name   rb      Return Exif tags tags   exifread process file f

I usually use pyexiv2 to set exif information in JPG files  but when I import the library in a script QGIS script crash  I found a solution using the library exif  https   pypi org project exif  It s so easy to use  and with Qgis I don  t have any problem  In this code I insert GPS coordinates to a snapshot of screen  from exif import Image with open file name   rb   as image file      my image   Image image file   my image make    quot Python quot  my image gps latitude ref exif lat ref my image gps latitude exif lat my image gps longitude ref  exif lon ref my image gps longitude  exif lon  with open file name   wb   as new image file      new image file write my image get file

Here s the one that may be little easier to read  Hope this is helpful   from PIL import Image from PIL import ExifTags  exifData      img   Image open picture jpg  exifDataRaw   img  getexif   for tag  value in exifDataRaw items        decodedTag   ExifTags TAGS get tag  tag      exifData decodedTag    value

I use this  import os sys from PIL import Image from PIL ExifTags import TAGS  for  k v  in Image open sys argv 1    getexif   items            print   s    s     TAGS get k   v    or to get a specific field  def get field  exif field      for  k v  in exif items         if TAGS get k     field          return v  exif   image  getexif   print get field exif  ExposureTime
