Nano Banana Prompt Tutorial
Learn how to build stronger image prompts using clear building blocks: subject, style, lighting, camera, composition and mood.
1. Start with the subject
Say what the image is actually about first. Strong prompts usually begin with a concrete subject, not abstract adjectives.
2. Add visual direction
Use style, lighting, camera language and composition to steer the model toward the look you actually want.
3. Finish with mood
Mood is the emotional glue. It makes a prompt feel cinematic, premium, dreamy, eerie, elegant or playful.

Your generated prompt
What good prompts do
They reduce vagueness. The model does better when you tell it what matters visually, rather than hoping it guesses your taste.
What weak prompts do
They rely on vague words like “nice”, “cool” or “beautiful” without enough direction. That often leads to generic, forgettable imagery.
Teaching tip
Get students to change one variable at a time. Swap only the lighting or only the camera language to see exactly what changed.
