Learn how I used Python in my daily life to convert 5,000 RAW images into the JPEG format.

Introduction

I have a folder with 4,902 RAW images and I want to convert them into the format JPEG to make it easier to share them with friends and family.

I wasn't sure how I would convert almost 5,000 RAW images into another format but Python had my back. A quick Google search brought up a similar Stack Overflow question from someone trying to do something similar.

I installed the modules rawpy and imageio with python -m pip install rawpy imageio and it took me a couple of lines of code to convert my first image.

I added a loop to go over all the images, I added a Rich progress bar to see my code working, and I was done.

Here is a screenshot of the code showing the progress bar, so I know it is still doing work:

The full code for this script can be found below. Now, I wonder... How much time would I have spent if I did not know Python?!
