E-commerce Photography — Side-by-Side Results
Prompt
"A 25–32-year-old woman with shoulder-length wavy dark hair, minimal makeup, wearing a light gray oversized hoodie and black biker shorts, holds a matte stainless steel insulated water bottle (product) close to the phone camera while looking slightly above the lens with a casual half-smile. Candid kitchen moment at a white countertop with a clean, uncluttered background, natural window light from the side, catalog-ready exposure and true-to-life colors like a Shopify listing. Include a “multiple angles” feel by showing a second view in-frame (mirror or quick hand-held tilt) that reveals the bottle’s full height and lid detail, still selfie-style and not editorial."
