Ever been curious to know which focal lengths (or ISO, or lens) you're using the most often in your pictures? This script extracts these values (if available) from the JPEG EXIF data and shows the usage count, optionally grouping the records by camera model.
You need the PIL library:
pip install PIL
usage: python lens-stats.py [-h] [-g] [-i | -l] DIRECTORY
Extracts stats from a picture folder
positional arguments:
DIRECTORY the directory to scan
optional arguments:
-h, --help show this help message and exit
-g, --group-by-camera
group by camera model
-i, --iso extract ISO value
-l, --lens extract lens model
The script will look recursively for all JPEG files within the folder. Example output:
» python lens-stats.py .
