Read the exact prompt
A slow, precise camera orbit moves from the front three-quarter view towards the side of this orange suede running shoe. The shoe stays perfectly still on the limestone. Gentle blue sea ripples move in the background and a natural glint travels across the amber sole. Warm late-afternoon light, realistic texture, subtle shallow depth of field. One continuous product shot, no cuts, no added objects, no lettering or shape changes. Preserve product identity, shape, and package proportions. Keep brand text and logos readable; avoid hallucinated text or misspellings. Use smooth natural motion and coherent camera movement with no warping. Maintain commercial-grade lighting consistency and realistic material behavior. Do not alter core packaging design elements or create extra products.
