Wedding Photography — Side-by-Side Results
Prompt
"A late-20s woman with long wavy brown hair in a simple white slip dress and an oversized denim jacket holds her phone up for a mirror selfie, glancing toward the camera with a shy smile while her partner (late-20s man in a rolled-sleeve white button-down and tan chinos) adjusts a small bouquet behind her. They’re in a cozy apartment bedroom with an unmade bed, string lights, and a few wedding invite samples on the dresser—soft warm window light, dreamy bokeh in the background, candid “getting ready” vibe like an Instagram story. Natural, slightly imperfect framing from a phone camera, authentic and intimate rather than posed."

Flux Ultra 1.1 Strengths
- Exceptional photorealism for bridal close-ups, with strong micro-detail in lace, beadwork, veils, and bouquet textures
- Premium-looking lighting and depth that can resemble high-end editorial wedding photography
- Ultra-high detail holds up well for full-resolution hero images (invites, website headers, album covers)
- Strong results for romantic couple portraits where natural skin rendering and realistic bokeh are priorities
GPT-Image 1.5 Strengths
- Strong prompt adherence for specific wedding shot lists (e.g., “first kiss,” “ring exchange,” “recessional,” “golden hour couple walk”)
- Versatile output for varied wedding styles (classic church, modern rooftop, beach elopement, rustic barn) and composition requests
- Handles detailed scenes well—multiple people, décor, aisle florals, and venue context—when you need story-rich ceremony frames
- Flexible quality tiers (8/16/32 credits) to match the task: quick concepts vs. polished finals
Verdict
If your priority is premium photorealism and ultra-fine bridal detail—think hero bridal portraits, editorial couple shots, and high-end album cover imagery—Flux Ultra 1.1 is the stronger “wow” option at a consistent 16 credits per image.
If you need reliable control and variety across a full wedding gallery (specific moments, venue-accurate scenes, different styles) and want to scale quality up or down by budget, GPT-Image 1.5 is often the better workflow choice—especially when prompt precision matters as much as realism.
