In July 2017, SPRING/Guinea held a six-day training with illustrators and the IT manager from Guinea and Sierra Leone, Peace Corps Guinea staff, and volunteers on a graphic design technique known as the Photo-to-Illustration (PTI) process. The PTI process involves taking a reference photograph, tracing a line drawing, and using graphic design software to add color, shading, and patterns for a realistic image that is useful in social and behavior change communication visuals for nutrition, health, and agriculture.
