​In the tradition of portraiture, portraits express the implication, imagination, or critique through a person's identity by their color of skin, gender, expression, eyes, clothing, or background details. In the series "Anonymous Existence", however, I attempt to create an "anonymous portrait" that challenges the dependence of portraiture on identity. I use infrared images to capture spontaneous thermal information, and AI-generated digital strokes to erase information about the person's race, nationality, and even facial emotions. By doing this, I hope to create portraits that are more fundamental and closer to the essence of life, and create portraiture without the interference of identity thought.
