Grainy 35mm Street Photography

Transform this photo into authentic 35mm street photography shot on Kodak Tri-X 400 black and white film. Apply heavy natural grain throughout the image. Convert to true black and white with rich tonal range: deep blacks, bright highlights, and smooth mid-tones. Add slight vignetting around the edges. The contrast should be punchy but not harsh. Simulate the look of being developed in a darkroom with slight inconsistencies in exposure. The person should look like they were candidly captured by a street photographer. Add subtle motion blur to the background as if shot while walking. The overall mood should be documentary and raw.
