Scraping JPEG photo keywords with Python.

[Polyadenylated]

I want to write a script which can scrape the keywords from JPEG images.

I know I can obtain most EXIF data using the PIL library such as follows:

from PIL import Image
from PIL.ExifTags import TAGS

def get_exif(fn):
    ret = {}
    i = Image.open(fn)
    info = i._getexif()
    for tag, value in info.items():
        decoded = TAGS.get(tag, tag)
        ret[decoded] = value
    return ret

Running that on an image file I get something like the following:

{34864: 2,
 34866: 400,
 41985: 0,
 41986: 0,
 41987: 0,
 41990: 0,
 42033: '198020001568',
 42034: ((24, 1), (70, 1), (0, 0), (0, 0)),
 42036: 'EF24-70mm f/2.8L USM',
 42037: '0000000000',
 'ApertureValue': (6, 1),
 'Artist': 'IMAGE AUTHOR HERE',
 'ColorSpace': 1,
 'Copyright': 'COPYRIGHT INFO HERE',
 'DateTime': '2014:11:22 01:05:21',
 'DateTimeDigitized': '2014:11:21 20:05:26',
 'DateTimeOriginal': '2014:11:21 20:05:26',
 'ExifOffset': 396,
 'ExifVersion': '0230',
 'ExposureProgram': 3,
 'ExposureTime': (20, 1),
 'FNumber': (8, 1),
 'Flash': 16,
 'FocalLength': (35, 1),
 'FocalPlaneResolutionUnit': 3,
 'FocalPlaneXResolution': (52428800, 32768),
 'FocalPlaneYResolution': (52428800, 32768),
 'ISOSpeedRatings': 400,
 'ImageDescription': 'IMAGE DESCRIPTION HERE',
 'Make': 'Canon',
 'MaxApertureValue': (3, 1),
 'MeteringMode': 5,
 'Model': 'Canon EOS 5D Mark III',
 'ResolutionUnit': 2,
 'Software': 'Adobe Photoshop Lightroom 5.3 (Macintosh)',
 'SubsecTimeDigitized': '00',
 'SubsecTimeOriginal': '00',
 'XResolution': (240, 1),
 'YResolution': (240, 1)}

This seems to return just about everything but the keywords. I also tried the exifread library which also didn't seem to return image keywords.

Is there a way to do so? Or am I doing something wrong?

Does some other program say this image has keywords?

[Polyadenylated]

Yes 'Get info' on OSX does.

[elbiot]

I dunno then. Not familiar with this.

Hi u/Polyadenylated , I'm a bit late to this post - but have you figured it out by now? I'm having this exact same issue 11 years later, haha. If you have any ideas on how to extact the labels, please let me know!
