An elderly man, weathered by time and hardship, sits on a dilapidated bench in an urban alleyway, his face etched with the lines of a lifetime's worth of stories. Capture his raw humanity with a Canon EOS 5D Mark IV camera paired with a Canon EF 24-70mm f/2.8L II USM lens. Set the aperture to f/4, ISO to 800, and use natural lighting for authenticity. Aim for a gritty, black-and-white rendering to convey the harsh realities of life. Achieve an output resolution of 6720 x 4480 pixels to preserve every detail.
