Shot: low angle, camera at ground level. A person sits on a curb; a high-top sneaker in the foreground is the intense focus, with all attention on its texture.

Detail to capture:
- the microscopic weave of the canvas upper
- scuff marks on the rubber sole
- the gritty, porous surface of the asphalt under the shoe

Background: out of focus (bokeh), with crisp specular highlights from wet city streetlights.

Technical specs:
- camera: Phase One IQ4, 150MP BSI CMOS sensor
- lens: 35mm wide-angle (adapted for perspective), f/2.8, ISO 100
- light: a mix of city sodium vapor light and controlled spectral bounce
- simulated real optical path with anisotropic reflection

Real-world imperfections on fabric and asphalt: oil, dust, light reflected by the lens, subsurface shadows.

Output: linear gamma, ProPhoto RGB, the equivalent of a 16-bit TIFF, color calibrated to D65, 600 PPI resolution.

Rules:
- no stylization, no post-enhancement, no bloom: raw optical realism only
- sharpness comes from real diffraction limits, never from digital sharpening
