Wedding Photography — Side-by-Side Results
Prompt
"A candid phone-camera selfie of a woman in her mid‑20s with long wavy brown hair, minimal makeup, wearing a simple white satin slip dress with a light cardigan and delicate pearl earrings, looking slightly off-camera while laughing and holding a small bouquet. She’s standing in a quiet city park beside a courthouse garden, golden-hour natural light with soft warm tones and dreamy bokeh, her partner (late‑20s, short dark hair) leaning in for a forehead kiss in the background. Authentic Instagram-story vibe, slightly imperfect framing, subtle motion blur from a real handheld shot."
