Saudade is a deep emotional state of nostalgic or profound melancholic longing for an absent someone that one loves, while simultaneously having positive emotions towards the future.
My father passed away when I was 15 years old. Before he died he wanted to emigrate to Portugal to write a novel. He never got there to fulfill his wish. Many years later I went to Portugal to photograph the story that has never been written. Saudade is a search for something that never happened.
