Wedding Photography — Side-by-Side Results
Prompt
"Mid-20s woman with long wavy brunette hair in a simple white slip dress and an oversized cream cardigan, holding her phone slightly above eye level for an Instagram Story selfie while glancing near the camera with a shy smile. She’s standing in a small city park garden next to her partner (late-20s man in a light linen button-down and beige trousers) as he gently adjusts a tiny bouquet in her hands, candid “pre-ceremony” vibes with soft warm golden-hour sunlight and dreamy bokeh from string lights behind them. Natural handheld phone-camera look, slightly imperfect framing, authentic skin texture, romantic wedding-photography feel without looking editorial."
