Ctrl+Paint is a free learning resource dedicated to the basics of digital painting. Each bite-sized video covers a different concept, allowing you to learn complex subjects in manageable increments.

This is the Library, where you’ll find all of the free Ctrl+Paint videos. If you’re a total beginner, try watching the videos in the order they’re listed! I’ve ordered these videos to ease you from traditional techniques into digital ones. If you’re looking for a specific topic, or want to build your own curriculum, I invite you to watch them in any order you like! Scroll down to see the whole list, and have fun painting!
