FLUX.2 Klein E-commerce-Grade Product Image Quality Rewriting

Based on the single-reference-image editing capability of FLUX.2 [klein] 9B, this demonstrates a prompt approach for "e-commerce-grade image generation": taking an ordinary casual product snapshot as the reference image, and using structured prompts to rewrite the lighting position, background, material reflections, and lens look all at once into a studio-grade product image, while preserving the product's own shape, color scheme, logo, and other identity features. The reference image is first generated by the production line (matte white background, soft ambient light, grayish casual-snapshot look), then handed to the image-to-image pipeline for same-composition rewriting, so developers can directly compare "what kind of input + what kind of prompt → what kind of final result." The prompt breaks the controllable items into four groups: lighting position and softbox arrangement, background and floor materials, material and reflection performance, and lens and depth of field. The step count is set to 4 (within the 4–8 range), matching the model's low-latency characteristics after step distillation and making it easy to reproduce in real-time pipelines. Suitable for batch production of e-commerce main images / detail page hero images, A+ content illustrations, brand asset style unification, and scenarios where old images need to be upgraded to a unified studio style without reshooting.
