In a visual journey of poetic images, the photographer examines how living with Parkinson's disease has changed her view of the world. Through the process, she commits to a more optimistic perspective. After discovering that she had Parkinson's disease, Torrance York focused her camera on the challenge to integrate this life-altering information into her sense of self. In Semaphore, York presents photographs of nature, the human body, medical images, details from daily life, and of light, to speak metaphorically about her shift in perspective post diagnosis. Plunged into an experience often described as dark or isolating, York surfaces with quiet, generous and luminous images that bare human vulnerability, while inspiring optimism and connection. Over ten million people worldwide are living with Parkinson's disease. While this book is relevant to the Parkinson's community, it connects with others whose journeys require growth, patience, and perseverance to move forward. Torrance York earned an MFA in photography from Rhode Island School of Design and a BA from Yale.
