Nano Banana Prompts: Image Editing and Consistency

An image task can be easier to review when the prompt separates what changes from what stays. Pexo presents Nano Banana for image generation and editing, including text and character-oriented work. Those are advertised uses, not a guarantee that every render preserves every detail. For brand work, supply the exact product, mark and approved wording instead of asking the model to invent them.

Developer source. Google's Nano Banana examples describe image creation and editing (checked 2026-10-20). The prompts below are original text examples, not tested Nano Banana results in Pexo.

Background replacement

Keep the photographed backpack, its straps, zipper layout, color and logo unchanged. Replace only the background with a clean home entryway in soft daylight. Maintain the original product scale and leave space above it for approved copy.

Product consistency across settings

Use the approved bottle photos as the product reference. Create a second lifestyle image at a work desk. Preserve the actual bottle shape, cap, label and approved color name. Change only the setting and lighting.

Portrait crop

With the subject's consent, use the supplied portrait to create a tighter editorial crop. Keep the person's facial features, clothing and skin tone consistent. Replace no identifiable personal detail; use a neutral background.

These are prompt text examples. No Nano Banana outputs from these prompts are displayed here.

For a poster, provide the exact headline and ask for a clear text area:

Use the supplied product image and approved headline "Carry what matters." Create a vertical poster concept with the real bag centered and a simple light background. Keep the product geometry unchanged. Place the headline in a readable area, then verify every character before use.

For a multi-image campaign, repeat the same approved reference files and explicitly preserve color, mark and product proportions. Compare the resulting images side by side for continuity. The review goal is fidelity, not an assumed model success rate.

An approved still can become a reference for a short video brief. Describe the real product action and state which image details must carry into motion. Pexo's product video workflow is a task entry point; check whether your account accepts the still as a reference. Review the video separately, because consistency in an image does not prove consistency in motion.

Use a video workflow when movement is the deliverable. For a different image model, run the same edit request and reference, then compare product fidelity and text accuracy using the actual outputs. This page does not rank Nano Banana against another model.

Start at the Nano Banana page and describe the change in ordinary language. Upload only assets you are permitted to use. Pexo describes automatic model handling; confirm the model and controls in your session before naming an output. Inspect unchanged areas, faces, logos and text before approval.
