Photography Statistics

Python library to extract statistics from JPG EXIF tags and show it as a histogram both on the commandline as well as matplotlib histogram plots.

Credit goes to Jason Millwards photography-statistics for providing a good foundation and inspiration for this script.

The script works for the following EXIF tags:

  • FocalLength
  • ISOSpeedRatings
  • ExposureTime
  • LensModel

It has been tested on my entire image folder which contains approx. 125 000 pictures.

Installation

Requirements

  • python 3
  • matplotlib
  • exifread

Usage

photostats.py [--exif-tags tag1 [tag2 tag3 ...]] [--dir <dir>]

Results

$ python stats.py --exif-tags FNumber FocalLength ExposureTime ISOSpeedRatings --dir ./images/

Found 134 images for statistics.
