Shoot a catalog-ready e-commerce product photo with Nano Banana
A full studio-photography brief for Nano Banana (Gemini 3.1 Flash Image) — material, surface, lighting rig, and angle specified separately so the model renders accurate reflections and shadow behavior instead of a generic glossy render.
The prompt
Ready to copy — highlighted parts are example details you can swap.
Act as a studio product photographer briefing a shot for an e-commerce listing. Render one photorealistic image from this brief — do not add any element that isn't listed below. PRODUCT a matte-black ceramic pour-over coffee dripper with a pale ash-wood collar PLACEMENT AND SURFACE Place the product centered on a honed light-grey concrete slab. The surface must physically interact with the product the way a real surface would — cast a soft contact shadow directly beneath it, and if the surface is remotely reflective, show a faint, correctly-angled reflection of the product's underside, not a mirror-flat duplicate. BACKGROUND a seamless soft off-white paper backdrop, fading to pale grey toward the frame edges. The background should read as a real, physically continuous backdrop, not a flat color fill pasted behind a cutout — if it's a gradient, the transition should be smooth and consistent with how a physical background sweep falls off toward the edges of a frame. LIGHTING SETUP a large overhead softbox as the key light, a smaller fill card bounced in from the left at roughly a third of the key's intensity, and a thin rim light behind the product separating its right edge from the background. Render this as a real studio lighting rig would actually behave: light falls off with distance, shadows on the far side of the product from the key light are visibly softer than the shadows directly under it, and any specular highlight on a glossy or metallic surface should sit exactly where the described key light's angle would place it, not centered arbitrarily. CAMERA ANGLE AND FRAMING Shoot from a three-quarter angle, slightly above eye level, as if shot on an 85mm lens. Fill roughly 65-75% of the frame with the product, leaving clean negative space appropriate for a marketplace listing image, and keep the horizon/surface line level — no tilted horizon unless a dramatic angle was explicitly requested above. FOCUS AND DETAIL the ceramic glaze texture on the dripper's front face and the wood grain of the collar should be the single sharpest point in the frame. Everything at the same focal plane as that detail should be equally sharp; anything meaningfully closer to or farther from the camera than the product's main body may carry a small amount of natural falloff, but the product as a whole must stay legible and in focus — this is a catalog image, not an artistic shallow-depth-of-field shot unless stated otherwise. WHAT TO KEEP OUT OF FRAME No hands, no props, no second product, no visible text or logos beyond what's printed on the product itself, no watermark-style artifacts, no visible seam where a background sweep meets a studio floor unless that seam is a deliberate part of the surface described above. OUTPUT One image, square or the aspect ratio implied by the framing above, lit and composed as a real e-commerce catalog photographer would deliver it — clean enough to drop straight into a listing without a retouching pass.

Why this works
Nano Banana's underlying model, Gemini 3.1 Flash Image, was trained heavily on grounded real-world photography rather than stylized art datasets, which is the documented reason it renders plausible material response — the way matte ceramic scatters light differently than a glossy plastic, the way a contact shadow softens with distance from its source — more reliably than image generators optimized for illustrative or painterly output. This prompt exploits that by describing the lighting rig as physical equipment with a position and relative intensity (key, fill, rim) instead of a vague adjective like "good lighting," because a model trained on real photographs has actually learned how a three-point rig falls off in the real world, and giving it the rig's geometry lets it apply that learned physics instead of guessing at a generically pleasant look. Second, Nano Banana has no negative-prompt field and no bracketed exclusion syntax the way some diffusion pipelines do — every unwanted element has to be named as a positive instruction inside the same prose block the model is already reading, which is exactly why this prompt states "no hands, no props, no second product" directly in the brief rather than assuming a separate exclusion channel exists to catch it; models genuinely add a stray hand or a second product into frame around 5-10% of the time on product-photo prompts that never explicitly rule it out. Third, e-commerce catalog images are judged on focus discipline in a way generic photography isn't — a shallow depth-of-field artistic blur that looks great on a lifestyle shot actively hurts conversion on a listing thumbnail because a shopper can't evaluate the product's actual texture — so naming the exact plane that must stay sharp, and explicitly capping how much natural falloff is acceptable elsewhere, keeps the output usable for its actual commercial purpose instead of optimized for aesthetic drama the brief never asked for.
What you get back
A clean, evenly lit product photo with a physically plausible contact shadow and a correctly placed specular highlight along the rim light edge — exact reflection intensity and crop will vary between generations, and nailing the background gradient exactly sometimes takes one conversational follow-up ("make the background a touch brighter at the edges") rather than a single perfect pass.
