Wedding Photography — Side-by-Side Results
Prompt
"A mid-20s woman with long wavy brown hair in a simple white sundress and a light cardigan holds her phone at arm’s length for an Instagram Story, glancing near the camera with a shy smile while her partner (late-20s, short dark hair) leans in beside her, both wearing subtle gold rings. They’re in a quiet park garden with a small bouquet and a coffee cup on a bench, caught in a candid “just got engaged” moment with soft warm golden-hour natural light and dreamy bokeh in the background. Casual, real-life vibe, slightly imperfect framing like a handheld phone selfie, gentle romantic mood."
