They can accomplish an entire creative workflow from concept to final edit within a single, conversational interface. This represents a fundamental shift in the industry from creating isolated “tools” to building foundational “workflow layers,” proving the model was built for work, not just for play.
How to Write Nano Banana Prompts
Writing effective prompts for the nano banana ai model involves using natural language that is both descriptive and precise. Since the model is built on the
Gemini foundation, it has a deep, semantic understanding of the real world.
Core strategies include:
Be specific: Use simple text to describe what you want to change or create. For example: “remove the stain from the t-shirt” or “make her smile and add soft lighting”. The model can handle precise local edits without the need for manual selection or masking.
Use descriptive language: For image generation, use photographic terms (e.g., “photorealistic,” “close-up portrait,” “85mm lens,” “bokeh”) or artistic terms (e.g., “kawaii-style sticker,” “cel-shading”) to guide the model toward a specific aesthetic.
Reference the subject: When editing, prompts should explicitly reference the person, pet, or object in the image to ensure the model maintains its identity and consistency. This is a core strength of nano banana google and what sets it apart.
With the model excelling at “prompt-based image editing” and understanding natural language , the “prompt” becomes the new “layer” or “brush”. This shift dramatically lowers the barrier to high-level creative work and changes the core skills required for many creative roles. The role of a “prompt engineer,” or someone who can effectively communicate with an AI model, is emerging as a new and valuable skill in the creative industry.
