How to Use Nano Banana 2 Prompts for Better Product Photography

TL;DR

Nano Banana 2 is Google's image model (Gemini 3.1 Flash Image) known for consistent subjects, sharp text rendering, and native 4K output. Better product photos come from prompts that specify subject, material, lighting, camera angle, background, and mood in a fixed order. Vague prompts produce generic results; structured prompts produce catalog-ready images.

What Are Nano Banana 2 Prompts?

A Nano Banana 2 prompt is a written instruction that tells the model exactly what product to render, how it should look, and where it sits — covering material, lighting, camera angle, and environment in one pass. The more precisely a prompt defines these variables, the closer the output matches a real studio shoot.

Nano Banana 2 is Google DeepMind's follow-up to the original Nano Banana and Nano Banana Pro models. It combines Gemini Flash speed with Pro-level image quality, supports resolutions up to native 4K, and keeps a subject consistent across multiple generated images — a feature that matters for product catalogs where every angle needs to match.

Why Prompt Quality Matters

Prompt wording directly controls:

• Realism — vague prompts default to generic, plastic-looking renders
• Lighting accuracy — naming a lighting style (softbox, cinematic, natural window light) changes shadow direction and highlight intensity
• Brand consistency — reused wording keeps colors and backgrounds uniform across a product line
• Composition — camera angle and focal length terms decide whether a shot looks like a hero image or a lifestyle scene

How Nano Banana 2 Handles Product Photography Prompts

The model reads a prompt, reasons over it (it supports adjustable "thinking levels" for more complex requests), then renders the scene while trying to keep the product's shape, label, and proportions intact. Because it follows multi-layered instructions more strictly than earlier models, a prompt that lists subject, environment, and lighting separately tends to render more accurately than a single run-on sentence.

Before vs. After

Weak prompt: "A nice photo of a watch." Optimized prompt: "Luxury steel watch, macro shot on black velvet, dramatic side lighting, reflective dial, 4K photorealistic, no background clutter."

The first prompt leaves lighting, angle, and background to chance. The second locks in every variable that affects how buyers perceive quality.

Common Prompt Mistakes

• Vague wording — "make it look good" gives the model no direction
• Missing lighting terms — leads to flat, inconsistent shadows
• Inconsistent backgrounds across a catalog — always reuse the same background phrase for a product line
• Overloading a single prompt — listing too many unrelated details confuses composition; keep to one clear scene
• Unrealistic requests — asking for physically impossible reflections or lighting can distort the product's actual shape

Best Practices Checklist

• Name the subject and material first
• Specify lighting style explicitly
• Include camera angle and lens/focal length
• Define the background or environment
• Add a mood or style descriptor
• Set aspect ratio to match the platform (1:1 for Amazon, 4:5 for Instagram)
• Add a negative prompt to exclude text, watermarks, or clutter
• Reuse the same phrasing across a product line for consistency
