This guide shows you how to prompt effectively, with real test case comparisons, plus pro workflows inside Photoshop.
Introduction
The Gemini-2.5 Flash Image (codename Nano Banana) was released at the end of August, and it instantly went viral.
From 3D figures to cyberpunk collabs, it powered weeks of internet hype. But while many users celebrated its colour accuracy and character consistency, others struggled with broken generations and mismatched prompts.
To bridge that gap, Google AI Studio published an official prompt guide. Combined with the new Flux Kontext Photoshop integration, Nano Banana is no longer just a meme — it’s a serious creative tool.
Prompting Principles
Golden Rule: Don’t list keywords → describe the scene.
Nano Banana thrives on natural language. A mini-story almost always outperforms a messy word list.
Six Core prompting scenarios
1. Photorealistic scenes
Template:
A photorealistic [shot type] of [subject], [action], in [environment]. Lit by [lighting]. Captured with [camera/lens]. Emphasising [details].
Example (official): Elderly ceramicist inspecting a tea bowl in golden hour.
Replica: Young chef chopping ingredients in a sunlit home kitchen.
2. Stylised illustrations & stickers
Template:
A [style] sticker of [subject], featuring [traits]. White background.
Example: Kawaii panda with bamboo.
Replica: GTA-style girl with sunglasses + tattoos.
3. Accurate text in images
Template:
Create a [design type] for [brand], with text “[text]” in [font]. [Style], [colour scheme].
Example: Minimalist logo “The Daily Grind.”
Replica: Retro logo “The Decker Store” with anchor icon.
4. Product mockups & commercial photography
Template:
Studio-lit product photo of [product] on [surface]. Lighting [setup]. Camera [angle]. Sharp focus on [detail].
Example: Black ceramic mug on polished concrete.
Replica: Whisky bottle with condensation on the crystal surface.
5. Minimalist & negative space design
Template:
A minimalist composition featuring [subject] in [position]. Vast [colour] background. Soft light. [Aspect ratio].
Example: Maple leaf with off-white negative space.
Replica: Seagull with baby blue ocean background.
6. Sequential art (Comics / Storyboards)
Template:
A single comic panel in [art style]. Foreground [character/action], background [setting]. Dialogue “[text]”. Lighting [mood].
Example: Noir detective under a rain-soaked streetlamp.
Replica: Cyberpunk heroine on skyscraper rooftop.
