E-commerce Photography — Side-by-Side Results
Prompt
"A 20s woman with shoulder-length wavy brown hair in a casual oversized gray sweatshirt and biker shorts holds a minimalist stainless-steel insulated water bottle close to the phone camera, glancing toward the lens with a relaxed half-smile like a TikTok UGC ad. Shot in a bright kitchen with a clean white countertop and uncluttered background, natural window light, catalog-ready clarity with a “multiple angles” feel (front-facing selfie plus slight tilt showing the bottle’s cap and logo). Casual handheld phone-camera framing, true-to-life colors, no glam retouching, authentic everyday moment."

Flux Ultra 1.1 Strengths

- Image-to-image editing for fast iteration (swap backgrounds, adjust styling, refine framing while keeping the core concept)
- High-resolution output suited to marketplaces and PDP requirements, with flexibility across brand styles
- Versatile looks for seasonal campaigns and multi-SKU collections (from minimal studio to lifestyle scenes)
- Practical for producing consistent variants from an existing reference image or prior approved creative
Verdict
Choose Flux Ultra 1.1 when your priority is the most premium, photorealistic product-on-model imagery straight from text—especially for hero shots where micro-detail and realism drive trust and conversions.

With equal pricing, Seedream 4.5 often wins for teams optimizing speed and variant production.
