Generates structured prompts for Gemini 2.5 Flash Image (Nano Banana) following best practices from October 2025. The main insight here is to write natural scene descriptions instead of keyword lists, which apparently works better for this model. You get templates for photography (with specific lens and lighting specs), product shots, landscapes, illustrations, and text rendering. It pushes 50-100 word prompts as the sweet spot and includes a multi-turn editing workflow since Nano Banana handles conversational refinements well. The checklist format is practical: subject, action, environment, lighting, mood, style, aspect ratio. If you're doing any serious work with this specific image model, the camera terminology and lighting references alone save you from fumbling around.
