In the last of our series on expat photographers, we meet Nicolas Witczak - for whom photography became his gateway into the world. After reading books and learning techniques through videos, Witczak's self-taught skills are seen through powerful and vibrant photos. To help him overcome his shyness and keep him motivated as a photographer, he has began posting one photo a day on his Instagram account. He wants his pictures to help people understand him, and help him understand the world.
