E-commerce Photography — Side-by-Side Results
Prompt
"A 20s woman with wavy dark-brown hair in a messy bun, wearing an oversized oatmeal hoodie and black leggings, holds a minimalist stainless-steel insulated water bottle (logo facing camera) while taking a casual phone selfie in a bright kitchen with a clean white countertop and light backsplash. She’s looking near the camera with a relaxed half-smile, one hand on the bottle and the other holding the phone, natural morning window light with soft shadows and catalog-clean clarity. Include a “multiple angles” feel by showing the bottle once in her hand and once set upright on the counter in the same frame, like a Shopify/Amazon lifestyle listing but still UGC-authentic."

Verdict
