Automate boring tasks with coding

I was 5 years into an design engineering role when I decided to learn coding to automate stuff.

In this very simple example I have three images of Darth Vader contained in an input folder. The code chunk below loads them all up and applies a filter and some text. Now imagine if you had three hundred images. Imagine if instead of just a filter, you apply a tonne of effects. The possibilities are endless.
