What are you actually using?

Separate the model from the place where you use it. A model is the AI system doing the image work; an app is the interface where you upload a photo and give instructions. Google introduced this editing capability inside the Gemini app. Its Gemini announcement explains that starting point.

A prompt simply means your written instruction. You do not need an elaborate character description or technical vocabulary for a first attempt. Write what should change, what should stay, and where you will use the result.

For a hypothetical candle shop, that might mean changing the table behind a jar while preserving its label and wax colour. Make those requirements your review checklist. For broader tool selection, use the ChatGPT versus Gemini business guide to frame your next comparison.

How do you edit a photo with Nano Banana?

Upload a photo to Gemini and describe one change. Google also describes continuing the conversation to make further edits to the resulting picture. The official editing walkthrough supports this simple approach.

1. Save the original. Keep an untouched copy for comparison and future attempts.
2. Choose the destination. Specify whether the picture is for a product listing, campaign draft or social post.
3. Write the protected details. List the label, shape, colour and accessories that must stay accurate.
4. Request one edit. Begin with the background before adding more changes.
5. Compare both pictures. Inspect the product itself before judging the new setting.
6. Give a precise correction. Identify the wrong detail instead of asking for a generally better result.

A first prompt for a hypothetical candle shop

Use the uploaded candle photo. Replace only the background with a plain warm grey surface. Preserve the jar shape, label lettering, wax colour and lid. Leave clear space above the product for a headline that I will add later. Do not add props or text.

Read the label closely when the result arrives. Compare the lid, glass edge and candle proportions with the original. Reject the picture if it makes the product look like a different item, even when the background looks excellent.

A useful follow-up would be: “The background works, but the lid is now wider. Restore the lid proportions from the original image.” If repeated corrections keep changing the product, stop that attempt and use manual editing for the affected area.

What makes Nano Banana Pro different?

Consider Pro when the brief involves more demanding composition or text inside the image. Google identifies Nano Banana Pro as Gemini 3 Pro Image and highlights improved text rendering and creative controls. The Pro announcement explains this positioning.

The model identities and positioning come from Google's comparison. The trial tasks and review criteria are recommendations for choosing between them.

Compare the same brief

Do not compare a simple original-model edit with a completely different Pro poster. Give both options the same photo, instructions and acceptance checklist. Then record how much correction each result needs.

For a hypothetical workshop poster, supply the approved headline yourself. Keep booking details and the date separately editable in your final layout. My recommendation is to judge the complete deliverable, including any manual finishing, before deciding whether an upgrade helps.

Where can businesses access it, and is it free?

Check the Gemini app first for individual editing. Google's original announcement also names Google AI Studio and the Gemini API for developers, plus Vertex AI for enterprise use. An API is a connection that lets one piece of software request work from another. Google lists those access routes here.

The Pro launch announcement describes limited free quotas in Gemini and higher quotas with paid plans. It also describes introducing Pro into Google Ads. These are launch details, not a promise that your present account has unlimited free access. Read the access section and check the conditions shown in your account.

Before committing, confirm the available model, any payment request and your usage allowance. Do not treat an app subscription as proof that separate developer usage is included. Ask whoever manages your account to confirm the exact route you intend to use.

For occasional pictures, my recommendation is to postpone integration work. If your team needs a repeated catalogue process, first document one successful manual run. Use the team training guide to turn that run into a shared working method.

Which business tasks are worth trying first?

Choose work where you can clearly distinguish the creative setting from the product promise. The following hypothetical briefs are starting points. Replace the product details and destination before using them.

A florist preparing a seasonal campaign

Place this bouquet against a quiet cream background. Preserve the flowers, wrapping and ribbon shown in the supplied photo. Keep the bouquet fully visible and leave space on the left for campaign copy. Add no extra flowers, containers or price labels.

Ask the florist to check the arrangement before approving the image. Do not accept a prettier version with a different bouquet. Connect the finished picture to a specific offer using the florist marketing guide.

A maker preparing an online listing

Use this photograph of a handmade mug. Simplify the background while preserving the handle, glaze pattern and rim. Keep the mug at the same viewing angle. Do not smooth out marks that are part of the actual item.

For this hypothetical listing, keep an unedited product photo alongside your working files. Review the edited version against what the buyer will receive. If you are preparing your first shop, continue with the practical Etsy guide.

A marketing team presenting concepts

Prepare two background directions for the same approved product photo. Label both as concepts and ask the decision-maker to choose a direction before requesting polished campaign files. Agree on the message and placement before spending time refining decorative details.

For logo work, I would treat an AI picture as a concept requiring further design work. Ask a designer to prepare the final shapes, lettering and usable files. Use the small business branding guide to define the brief before commissioning that work.

How should you review results and run a weekly trial?

Approve accuracy before appearance. Google's original announcement acknowledges ongoing work on long text, consistent likeness and fine factual details. That makes a close product check a sensible part of your process. The developer announcement identifies those limitations.

• Compare shape, colour and packaging with the original.
• Read every label, headline and contact detail.
• Check that added props do not imply included accessories.
• Inspect edges, reflections and repeated patterns.
• View the picture at its intended display size.
• Record who approved the final file.

Before uploading, confirm that you have permission to use the source material. Remove customer details from the working image and avoid sharing confidential product launches without approval. Make the person responsible for the image clear from the start.

A manageable trial for this week

Pick one product and one placement. Prepare a background edit, review it, and write down the time spent on corrections. Repeat with another source photo only after the first result passes your checklist.

Use three possible decisions: keep the process, narrow its use, or stop using it for that task. A reasonable outcome might be keeping AI for campaign concepts while retaining conventional photography for detailed listings. Treat that as a useful finding rather than forcing every image through the same tool.

Before adding an approved file to your website, work through the image optimisation guide. Keep the original, approved export and prompt together. That gives the next person a clear starting point when the campaign needs another version.
