Explore The New Nano Banana PRO in Photoshop

Nano Banana PRO Changes the Whole Scene Around Your Subject

Compositing a person into a new background is a real job. You cut them out, you fix the edges, you match the color temperature, you rebuild the light on their face, and if the clothes are wrong for the new setting you’re looking at another hour of work or a reshoot.

Nano Banana PRO — Google’s Gemini 3 model, now available inside Photoshop’s Generative Fill — does the whole thing from a sentence. You select the canvas, describe the scene you want, and it rebuilds the background, matches the lighting, and keeps your subject recognizably themselves. It will change their clothing in the same pass if you ask.

What This Model Does Differently

It Understands Conversational Prompts

You don’t need prompt syntax or keyword stacking. “Place the subject on a rooftop in a major city and match the lighting” is a sentence, and it works as one.

The Subject Stays the Same Person

The main failure of earlier generative background work was identity drift — the face came back subtly different. Nano Banana PRO holds the subject’s features consistent while everything around them changes.

It Relights Rather Than Pastes

Ask for a beach and the light on your subject changes to match a beach. That relighting step is the one that used to take the longest by hand, and it’s the reason the results integrate instead of looking cut out.

Select the Canvas and Open Generative Fill

1. Select All

   Select > All, or Cmd/Ctrl + A. This is counter-intuitive if you’re used to selecting the thing you want to change — here you’re telling the model the entire frame is available to rework, subject included.

2. Click Generative Fill

   It appears in the Contextual Task Bar as soon as the selection is active.

3. Choose Nano Banana PRO From the Model List

   The panel defaults to Adobe’s own Firefly model. You have to pick the advanced model explicitly — skipping this step is why people try the workflow and wonder what the fuss was about.

Write the Prompt in Plain English

4. Describe the Scene You Want

   Write it the way you’d say it: “place the subject in a beach scene and match the lighting to the background”, or “place the subject on top of a rooftop in a major city”. Naming the lighting explicitly is worth doing — it’s what pushes the model toward integrating the subject rather than compositing them.

5. Combine Background and Wardrobe in One Prompt

   This is where it gets genuinely useful: “place our subject into a stadium and change their clothing to match the colors of that stadium”. Two jobs that would normally be two separate pieces of work, handled in one generation.

6. Click Generate

   The model returns quickly, and each result arrives on its own generative layer with your original untouched underneath.

Review the Variations

7. Click Through the Options in the Properties Panel

   Compare them on the things that are hard to fix afterwards — the direction of the light, the edge where the subject meets the background, and whether the perspective of the new scene matches the angle the subject was photographed from.

8. Keep the Generative Layer Rather Than Flattening

   Every result sits on its own layer above the original. That means you can mask parts of the generation away, or reveal a piece of the real photograph underneath, which is often what turns a good generation into a convincing one.

What It Costs

Nano Banana PRO is a partner model, so it draws on generative credits at a much higher rate than Adobe’s own Firefly models — roughly ten credits per generation at the time of writing, against one for standard Firefly features. Adobe has flagged that figure as promotional, so check the current cost by hovering over the model icon in the Properties panel before you generate.

On plans with unlimited standard Generative Fill this is still a metered feature, and on a limited monthly balance it will empty it quickly. The practical approach is the one that applies to every partner model: explore with the cheap options, then spend the expensive generation once you know what you’re asking for. Our free guide to generative credits covers which tools cost what.

Where It Still Falls Short

Vague Prompts Get Generic Scenes

“A nice background” produces exactly what you’d expect. Specific settings, specific times of day, specific light — the more you decide, the less the model decides for you.

Mismatched Camera Angles

A subject shot from below placed into a scene rendered at eye level reads as wrong even when every other element is right. Look at perspective first when comparing variations.

Hands, Text and Fine Detail

Still the weak spots of generative models generally. Zoom in on them before accepting a result.

Regenerating Instead of Rewriting

At ten credits a go, a second attempt with the same prompt is an expensive way to hope. Change the prompt.

What This Changes, and What It Doesn’t

A tool that relights a subject into a new environment from a sentence removes the most laborious part of compositing. That’s a real change, and it’s worth being direct about: some work that used to take an afternoon now takes a minute.

What it doesn’t remove is the judgement. Knowing that the light is coming from the wrong side, that the perspective doesn’t match, that the edge is too clean to be real — those are the things that separate a composite that holds up from one that doesn’t, and they come from having done it by hand. The model generates; you still have to be able to see.

Try It on a Portrait

Select All, open Generative Fill, switch the model to Nano Banana PRO, write a full sentence describing the scene and the light, and generate. Download the three free sample images and the layered PSDs, and work through the exact prompts first — then write your own for a portrait where the background let the picture down. For the manual compositing skills that tell you whether a generation is actually working, our PRO Photoshop Learning Path is where to go next.
