Food Photography — Side-by-Side Results
Prompt
"Casual influencer food post: a woman in her mid-20s with shoulder-length wavy brown hair wearing an oversized cream sweater, leaning on a kitchen counter and glancing toward the phone camera with a relaxed half-smile while holding a fork mid-air. In front of her is a beautifully plated avocado toast with poached egg and chili flakes on a ceramic plate, styled with a rumpled linen napkin, matte-gold cutlery, scattered microgreens, and a latte in a glass mug; shot at a dramatic 45-degree angle with soft window light and slight handheld phone-camera realism. Cozy, everyday “quick lunch at home” vibe—authentic and not overly polished."
