Digital Photography
In this part, we explore digital photography and more generally digital images. It is also an opportunity to talk about EXIF data, RGB colors, but also to manipulate images using the Python language.
Introduction
Digital photography is now obvious to us. But it has only existed for a few decades, and its ancestors were just as fascinating. Let's dive into history!
RGB Colors
There are several ways to encode colors. The RGB mode (for Red, Green, Blue) is the most commonly used.
Image Manipulation in Python
Digital image manipulation in Python is made easy thanks to the **PIL** package (Python Image Library). We will do some basic manipulations.
EXIF Data
EXIF data is information that can be associated with digital images. They are called **metadata**: this means they serve to describe other data, here a digital image.
