How to Create AI Product Photography with Nano Banana Pro
Nano Banana Pro is the highest-resolution image model on Astorie, offering 1K, 2K, and 4K output tiers. At 4K, product textures — leather grain, brushed metal, fabric weave — render with enough detail for print catalogs and large-format displays. Unlike Imagen 4 (text-only), Nano Banana Pro supports up to 8 reference images, making it powerful for creating product shots that maintain visual consistency with existing brand assets or reference photos.
Step-by-Step Guide
Choose resolution based on final output destination
Nano Banana Pro has three resolution tiers: 1K, 2K, and 4K. For social media and web thumbnails, 2K is sufficient and renders faster. For Amazon zoom-in product viewers, e-commerce hero images, or any print material, 4K is the right choice — the texture detail at 4K makes product labels readable and material finishes distinguishable (matte vs. satin vs. gloss).
Use reference images for brand consistency
Nano Banana Pro accepts up to 8 reference images — a unique capability among product photo models. Upload existing product photos, brand style guides, or mood board images as references, then describe the new shot you want. The model maintains visual style, color palette, and aesthetic from the references while generating a new composition. This is invaluable for creating consistent product series where every image needs the same lighting and staging style.
Select output format for your workflow
Choose between JPEG and PNG output. JPEG produces smaller files ideal for web and social media. PNG preserves lossless quality needed for print production and post-processing in design tools. For product images that will go through further editing (background compositing, retouching), always use PNG to avoid compression artifacts. For images going directly to web listings, JPEG saves storage without visible quality loss.
Generate multiple variants with batch count
Set the count to 2-4 to generate multiple compositions from the same prompt in one run. Each variant introduces natural variation in angles, lighting emphasis, and element placement. Compare them side by side on the canvas, then select the strongest for the final 4K render. This batch-then-upscale workflow keeps exploration efficient: ideate at 2K with 4 variants, then re-render only the best at 4K.
Prompt Examples
Luxury macro photography — "macro level detail on leather grain and brushed metal" specifically leverages 4K resolution. At 1K/2K, this level of material detail washes out. The "dark walnut surface" and "dramatic side lighting" create the premium aesthetic that luxury brands require.

Minimalist lifestyle shot — the "Japanese aesthetic, clean and serene" style anchor guides the model toward restrained, intentional compositions. Reference images of existing Japanese-style product photography would further refine this direction.

Parameter Tips
Three resolution tiers: 1K, 2K, and 4K. 4K is only worth choosing when the image will be viewed at full size (product zoom, print, large displays).
Use PNG output format for print materials and post-processing. Use JPEG for web-only images to save file size.
Up to 8 reference images can be attached — use existing product photos or brand style guides to maintain visual consistency across a product catalog.
The batch-then-upscale workflow is the most efficient: generate 4 variants at 2K, pick the best, then re-render at 4K for the final image.
What to Expect
Nano Banana Pro at 4K delivers the highest-resolution product images on Astorie — print-ready quality with visible material textures. Compared to Imagen 4 Ultra (also photorealistic), Nano Banana Pro supports reference images and batch generation — essential for product catalogs where consistency matters. For fast product concept exploration, Imagen 4 Fast renders quicker. For editing existing product photos, use FLUX Kontext instead.

FLUX Kontext
FLUX Kontext is the best model for product photography that requires placing your actual product into new scenes. Unlike Imagen 4 (which imagines a product from text) or Nano Banana Pro (which composites from multiple references), FLUX Kontext takes your real product photo and re-contextualizes it — swapping backgrounds, adjusting lighting, and placing the product in lifestyle scenes while preserving the exact appearance of labels, colors, and textures. Two quality tiers are available: Pro for standard shots and Max for hero images requiring maximum detail fidelity. You can generate 1-4 images per run across 9 aspect ratios.
View guideImagen 4
Imagen 4 is the best choice when you need to create product photos from a text description alone — no reference photo required. It generates photorealistic images with exceptionally accurate lighting, material rendering, and surface detail. The three-tier quality system (Fast, Standard, Ultra) lets you iterate quickly on concepts with Fast, then render the final hero shot at Ultra for near-studio quality. Unlike FLUX Kontext or Nano Banana Pro, Imagen 4 is text-to-image only — it imagines the product from your description rather than editing an existing photo.
