Learn how to use animation as a narrative tool to emphasize an idea and develop a concept
Animation can be a powerful tool for telling a story. Over the years, illustrator Martín Tognola, whose clients include The Washington Post and The New York Times, has mastered the art of explaining things using animated loops.
In this course, learn how to use animation as a narrative tool for illustrating while also learning how to use Procreate. Your goal is to create a graphic solution for an idea, text, or script and convey the core message using only your animated loop. By the end of this course, you’ll be able to add motion to any illustration and bring it to life using Procreate.
