Options

• --tags TAGS Comma-separated list of EXIF tag names or IDs to filter.

• --thumbnail Show EXIF tags from image thumbnails instead of the main image.

• --json Output EXIF data as JSON instead of a table.

Examples

# View EXIF data for a single image
tagkit view image.jpg

# View EXIF data for all JPGs in a folder
tagkit view "*.jpg" --glob

# Filter by specific tags
tagkit view image.jpg --tags Make,Model

# Output as JSON
tagkit view image.jpg --json

API Usage

Extract EXIF Data

from tagkit import ExifImageCollection

# Get EXIF data for one or more images
exif_collection = ExifImageCollection(['image1.jpg', 'image2.jpg'], tag_filter=['Make', 'Model'])

# Access EXIF data for each file
for file_path, exif_image in exif_collection.files.items():
    print(f"File: {file_path}")
    for tag in exif_image.tags.values():
        print(f"  {tag.name}: {tag.formatted_value}")

Working with ExifTag

from tagkit.core.tag import ExifTag

tag = ExifTag(id=271, value="Canon", ifd="IFD0")
print(tag.name)             # e.g., "Make"
print(tag.exif_type)        # e.g., "ASCII"
print(tag.formatted_value)  # e.g., "Canon"
print(tag.as_dict())        # Dict representation

---

Notes

• Any EXIF bytes that cannot be decoded as UTF-8 will be displayed as base64-encoded strings.
• Shutter speed, aperture, and ISO are formatted in a style familiar to photographers.
• The CLI and API are extensible for custom workflows and formatting.
