Wedding Photography — Side-by-Side Results
Prompt
"A candid phone-camera selfie of a mid-20s bride-to-be with long wavy brown hair in a simple white slip dress and oversized denim jacket, holding a small bouquet and looking just past the lens with a nervous-smile while walking through a sunlit city park path. Her partner (mid-20s, short dark hair) steps into frame adjusting his tie and laughing, with soft warm golden-hour light, dreamy bokeh trees behind them, and a “real Instagram story” vibe (slightly imperfect framing, natural skin texture). Romantic wedding-photography feel but captured like an everyday moment on a smartphone."

GPT-Image 1.5 Strengths
- Strong prompt adherence for precise bridal details (gown silhouette, veil length, bouquet type, hair and makeup notes)
- High-fidelity, detailed scenes that handle ceremony context well (aisle décor, altar florals, venue architecture)
- Reliable composition control for classic wedding framing (full-length bridal, three-quarter portraits, wide ceremony establishing shots)
- Flexible quality tiers (8/16/32 credits) to match quick concepting vs hero-image generation
Seedream 4.5 Strengths
- Built-in image-to-image editing for wedding-specific refinements (adjusting dress details, bouquet colors, background cleanup)
- High-resolution output that suits print-like bridal portraits and crisp couple close-ups
- Versatile styles for different wedding aesthetics (editorial, film-inspired, airy romantic, moody candlelit)
- Straightforward per-image pricing (16 credits) that’s easy to budget for iterative edits
Verdict
Pick GPT-Image 1.5 when you need strong prompt accuracy and richly detailed scenes from scratch—ideal for generating bridal portraits and ceremony moments that closely match a written shot list. Its tiered pricing also makes it convenient for both rapid moodboarding (low) and polished deliverables (high).
Pick Seedream 4.5 when your wedding workflow involves refining images—especially if you want to iterate on an existing bridal or couple shot (swap floral palettes, adjust lighting mood, tidy backgrounds) while keeping the core composition. If editing and high-res consistency are central, Seedream 4.5 is often the smoother choice.
