How does it work?

exif_file_renamer.py was designed to automate renaming photo files with an information useful for photographers e.g. date, exposure time and aperture. It extracts metadata from image files and uses it to rename them.

New filename follows this pattern:

DATE_TIME_FOCALLENGTH_EXPOSURE_APERTURE_ISO

Example:

180515_16025102_70mm_1-360s_f7.1_ISO-1600

The script is looking for JPG files first, but it also checks for Nikon RAW (.nef) files of the same name and renames them as well if they're exist.

Installation

Make sure you have Python installed. You can check it by running this command in terminal:

python

You'll also need a pip package manager. Download get-pip.py file and run:

python get-pip.py

Alternatively you can run this command:

python -m pip install --upgrade pip

Once pip is installed you need to install Pillow. It's a fork of Python Imaging Library used by python-exif-file-renamer for extracting EXIF data from images.

Run this command:

python -m pip install --upgrade Pillow

And you're ready to go!

Usage

Run exif_file_renamer.py script and pass (as an argument) path to the folder containing photos you want to rename.

You can do this by navigating to the directory with the script and running the following command:

python.exe exif_file_renamer.py MyFolder

You need to specify an absolute path for the directory.
