There is a poster of a town with a mountain in the background

Create a retro-style travel poster. The poster should feature a scenic landscape with Ponderosa pine trees, a small-town main street with historic buildings, and a backdrop of mountains. Include people enjoying outdoor activities like hiking or picnicking. The overall color palette should include warm, inviting tones with a vintage feel. Camera and Settings: Use a Canon EOS 5D Mark IV with a 24-70mm f/2.8 lens. Settings: ISO 100, aperture f/8, and shutter speed 1/125s to capture a sharp, vibrant image with a wide depth of field. The poster should have a slight grain effect to enhance the retro aesthetic.
