MyArwReader 0.1.1

A lightweight package to read metadata from Sony .ARW files

MyArwReader

A lightweight Python package to read metadata from Sony .ARW files.

Overview

MyArwReader provides a simple interface to extract metadata from .ARW files using the pyexiftool library. It supports accessing all metadata tags (EXIF, XMP, IPTC, etc.) or specific tags like ISO, camera model, or timestamp.

Installation

pip install path/to/MyArwReader-0.1.0-py3-none-any.whl

Requirements
Python: 3.6 or higher
pyexiftool: Installed automatically as a dependency
exiftool: Must be installed separately and available in your system PATH. Download from the official ExifTool website and follow the installation instructions.


Usage
Basic Example
Extract specific metadata tags from an .ARW file:

from MyArwReader import ARWReader

file_path = "path/to/your/file.ARW"
reader = ARWReader(file_path)
print(f"File: {reader.file_path}")
print(f"ISO: {reader.get_tag('EXIF:ISO')}")
print(f"Camera: {reader.get_tag('EXIF:Model')}")
print(f"DateTimeOriginal: {reader.get_tag('EXIF:DateTimeOriginal')}")

Full Metadata Example

from MyArwReader import ARWReader

reader = ARWReader("path/to/your/file.ARW")
metadata = reader.get_metadata()
print(metadata)

Batch Processing Example
Process multiple .ARW files in a directory:

import os
from MyArwReader import ARWReader

arw_dir = "path/to/your/arw/files"
file_paths = [os.path.join(arw_dir, f) for f in os.listdir(arw_dir) if f.lower().endswith('.arw')]

for file_path in file_paths:
    reader = ARWReader(file_path)
    print(f"File: {reader.file_path}")
    print(f"ISO: {reader.get_tag('EXIF:ISO')}")
    print(f"Camera: {reader.get_tag('EXIF:Model')}")
    print(f"DateTimeOriginal: {reader.get_tag('EXIF:DateTimeOriginal')}")
    print()

Methods
get_metadata(): Returns a dictionary of all metadata tags.
get_tag(tag): Returns the value of a specific tag (e.g., 'EXIF:ISO') or None if not found. For a list of Sony-specific EXIF tags, see the Sony Tag ID documentation. https://exiftool.org/TagNames/Sony.html

Notes
Ensure your .ARW file paths are valid; a FileNotFoundError will be raised if the file doesn’t exist.
Install exiftool separately and ensure it’s in your system PATH for pyexiftool to work. See the ExifTool download page for the latest version. https://exiftool.org/
