Fashion Photography — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy dark hair in a casual white ribbed tank, oversized denim jacket, and worn-in sneakers holds her phone slightly above eye level for a candid selfie, glancing near the camera mid-laugh like she’s filming an Instagram story. She’s standing in a real neighborhood café line with a tote bag and iced coffee, soft window daylight and a little background bustle, slightly imperfect framing like a quick TikTok thumbnail. Natural lighting only, authentic skin texture, no glam styling, everyday approachable vibe."
