Prompt: A middle-aged man sits on a park bench, head bowed in profound sadness, gazing at the ground. His silhouette portrays a sense of solitude and sorrow, as if his emotions are unattended and unacknowledged. The details in the scene are intricate, captured through the lens of a single-lens reflex (SLR) camera with a specific focus on using a 30mm lens. The composition emphasizes central focus, high contrast, and an exposed ambiance.
