Full comparisonCompare Models (select 4)
Wedding photography demands more than “pretty pictures”—you need believable skin tones, accurate fabric detail (lace, tulle, satin), flattering lighting, and consistent styling across bridal portraits, ceremony coverage, and romantic couple shots. Flux Ultra 1.1 and Seedream 4.5 are both premium options inside Influencer Studio, each priced at 16 credits per image.
Flux Ultra 1.1 leans into ultra-high detail and photorealism for polished, camera-like results. Seedream 4.5 pairs strong image quality with image-to-image editing, making it especially useful when you need to refine a pose, adjust composition, or iterate on an existing wedding look without starting over.
Wedding Photography — Side-by-Side Results
Prompt
"A candid iPhone selfie of a mid‑20s woman with long wavy brown hair in a simple white slip dress and light cardigan, holding a small bouquet and looking slightly past the camera with a shy smile while her partner (late‑20s man in a rolled‑sleeve white shirt and beige trousers) leans in close behind her. They’re standing on a quiet park path near a gazebo with string lights, soft warm golden-hour sunlight, dreamy bokeh, and a slightly imperfect “Instagram story” framing like they just captured a quick wedding-day moment. Natural lighting, realistic skin texture, subtle motion blur from the handheld phone-camera."

Flux Ultra 1.1 Strengths
- Exceptional photorealism for bridal portraits, with crisp detail in skin texture, makeup, and hair
- Strong rendering of intricate wedding materials (lace patterns, beading, veil transparency) and fine highlights on satin
- Premium “finished” look that suits editorial-style couple portraits and hero images for wedding campaigns
- Reliable high-detail output for close-ups (rings, bouquet details, dress bodice) without the scene feeling soft
Seedream 4.5 Strengths
- Image-to-image editing for practical wedding workflows (refine framing, adjust styling, iterate on a selected pose)
- Versatile styling range—from classic film-inspired ceremony coverage to modern editorial couple shots
- High-resolution output that holds up for wide ceremony scenes and venue backdrops
- Efficient for consistency: reuse a base image and make controlled variations for an album-like series
Verdict
If your priority is maximum photorealism and ultra-fine detail—especially for bridal hero portraits and close-up wedding details—Flux Ultra 1.1 is the stronger pick. It’s well-suited to “final deliverable” images where fabric realism and facial detail matter most.
If you expect to revise and refine (for example, adjusting a couple’s pose, reworking a ceremony angle, or keeping a consistent bridal look across multiple variations), Seedream 4.5 stands out thanks to its image-to-image editing and flexible styling. Since both cost 16 credits per image, the best choice comes down to whether you value pure photoreal finish (Flux Ultra 1.1) or iterative editing control (Seedream 4.5).
