flux-3-image e-commerce-grade product still life: perfume shot with warm-cool collision

A set of product photography texture exercises for e-commerce detail pages and main image scenarios: with a perfume bottle still life as the sole subject, control the three things—"material, lighting, background layering"—through prompts, so that flux-3-image outputs high-completion images that can go directly into the post-processing pipeline. Structurally it is divided into two layers: the first layer uses a reference image to constrain the bottle's shape proportions and label position, using it as the subject reference in image_urls to prevent the model from freely improvising and causing the bottle shape to drift; the second layer explicitly describes photographic language in the prompt—a mix of hard light source and softbox, reflections on the acrylic surface, a background gradient from warm orange to cool cyan, shallow depth of field and slight highlight bloom—thereby obtaining the "clean yet textured" finished image common in e-commerce. At the parameter level, a 4:5 vertical aspect ratio is used to fit mobile main images, and the resolution tier is set to 2K to facilitate cropping and detail retention; grounding remains enabled by default, used to supplement material common sense not explicitly stated in the prompt (glass refraction, metal cap reflections). Applicable scenarios: e-commerce main images and detail page header images, advertising placement materials, and multi-style exploration during the product concept stage. The prompt structure can be directly transferred to other categories such as cosmetics, beverages, and headphones—just replace the subject and color description.
