2.4.1 Using PIL (Pillow)
PIL, now known as Pillow, is a Python library for opening, manipulating, and saving image files.
from PIL import Image
from PIL.ExifTags import TAGS
def extract_metadata_pil(image_path):
img = Image.open(image_path)
exifdata = img.getexif()
metadata = {}
for tag_id in exifdata:
tag = TAGS.get(tag_id, tag_id)
data = exifdata.get(tag_id)
if isinstance(data, bytes):
data = data.decode()
metadata[tag] = data
return metadata
if __name__ == '__main__':
image_path = 'example.jpg'
metadata = extract_metadata_pil(image_path)
for key, value in metadata.items():
print(f"{key}: {value}")2.4.2 Using ExifTool with Python
ExifTool is a command-line application for reading, writing, and editing metadata. You can use it with Python’s subprocess module.
import subprocess
def extract_metadata_exiftool(image_path):
command = ['exiftool', image_path]
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = process.communicate()
metadata = {}
for line in stdout.decode().split('n'):
if ': ' in line:
key, value = line.split(': ', 1)
metadata[key.strip()] = value.strip()
return metadata
if __name__ == '__main__':
image_path = 'example.jpg'
metadata = extract_metadata_exiftool(image_path)
for key, value in metadata.items():
print(f"{key}: {value}")According to research from the Santa Fe University of Art and Design’s Photography Department, in July 2023, Python provides robust tools for metadata extraction, allowing for automation and customization in image processing workflows.
