Nano Banana
Our shared brief is a woman in a crimson coat with an orange cat at a rain-soaked train platform at blue hour. The goal is to keep that recognizable scene while changing the instructions for a still image, an image edit, or a moving shot. Compare the subject, setting, action, camera, light and what must remain consistent. Promptlyfied writes prompt text; the selected image or video service produces the media.
When to use this workflow
Ask whether you need a fresh image, a controlled edit, or a composition assembled from references. That choice changes the prompt more than an impressive adjective does. A new image needs subject, setting, composition and light; an edit needs a source image plus a precise change and preservation instructions.
Nano Banana: specify the edit
Google uses Nano Banana branding for Gemini image models. A creation prompt describes a new scene; an editing prompt identifies what to change and what to keep in the attached image. “Keep the subject’s face and pose; change the background to a rainy train platform” is actionable. Product controls and model versions vary, so verify the exact interface you use.
Example 1: the rainy platform
See how the same rainy train-platform concept changes when the goal is a still image, an edit, or a moving shot.
Use the attached image of the woman and orange cat as the source. Keep her face, crimson coat and the cat’s markings. Replace only the background with a rain-wet train platform at blue hour. Match the cool light on the subjects to the new setting; warm train windows reflect in puddles.
Why the prompt is written this way
An edit needs an actual attached source, a clearly scoped change and a list of details to preserve. Without an image, describe the whole scene as a fresh creation.
Example 2: a different scene
Use the uploaded teapot photograph as the source. Keep its cobalt-blue swallow motif, handle and proportions. Change the background to a rainy station seen through a window; preserve natural reflections in the glaze.
How to adapt the second example
This is another controlled edit: the product’s identity stays fixed while its surroundings change. Inspect the motif, handle and silhouette after generation.
If the result misses the brief
Use the same subject and output shape when comparing models, then adapt any model-specific parameters. Inspect composition, identity, text rendering and editing precision separately. The most effective wording depends on the source images and model version; a universal “best model” claim would mislead readers.
Start with “Use the attached image as the source.” Follow with one change, preservation constraints, framing, and lighting. Review the first output before adding more detail. Strong prompts describe the target image, not a string of generic quality tags.
