Background Photo Edits

5 prompts

Keep Subject Change Room

1/30

✨ What it does

Nano Banana keeps the adult in [YOUR PHOTO] and [OUTFIT] and rebuilds only the room as [SETTING] matching [LIGHT DIRECTION], 4:5. Check shoulder blend, then keep the take if no extra occupant appeared.

Using the uploaded [YOUR PHOTO], keep the adult, pose, [OUTFIT] and light on the skin exactly. Replace only the room with [SETTING], a quiet interior that matches the existing key from [LIGHT DIRECTION]. Blend shoulder edges. Add no extra occupant and no celebrity. Treat as 50mm at f/2.2. Crop 4:5. Nano Banana conversational edit (Gemini image model). Do not generate a new person from scratch.

💡

Pro tip: The phrase 'keep everything the same but the room' is the most reliable scope.

Soft Grey Paper Sweep

2/30

✨ What it does

Nano Banana lifts the adult in [YOUR PHOTO] onto grey seamless in [OUTFIT] with a contact shadow, 4:5. Inspect flyaways, then keep the sweep if it still looks like a studio photograph.

Edit [YOUR PHOTO] onto a seamless grey paper sweep. Preserve hair flyaways, face and [OUTFIT]. Soft contact shadow. No extra figure. Optics: 85mm at f/4. Crop 4:5. Nano Banana (Gemini image model) cutout edit, photoreal, not a sticker, not a new generated model.

💡

Pro tip: If the sweep goes pure white, restated 'medium grey paper' usually fixes it.

Coast Path Behind

3/30

✨ What it does

Nano Banana puts the adult from [YOUR PHOTO] on a coast path in [SETTING], keeps [OUTFIT], 3:2. Check foot contact and sky color on skin, then keep the still if the path is empty of extra hikers.

Keep the adult in [YOUR PHOTO] and [OUTFIT]. Replace the backdrop with a windy coast path in [SETTING], grass and sea, overcast. Match color on the face to the new sky. No extra hiker, no celebrity. Camera feel 35mm at f/4. Crop 3:2. Nano Banana instruction edit of the upload, feet planted on dirt, not a generated travel ad.

💡

Pro tip: Name the sea color (grey-green, not tropical turquoise) for northern coasts.

Bookstore Bokeh Wall

4/30

✨ What it does

Nano Banana holds the adult in [YOUR PHOTO] sharp, keeps [OUTFIT], and turns the backdrop into 85mm bookshelf bokeh, 4:5. Confirm spines are untitled, then keep the portrait if no extra reader appeared.

💡

Pro tip: Ask for 'untitled spines' so famous covers do not appear in the blur.

Concrete Gallery Wall

5/30

✨ What it does

Nano Banana stands the adult from [YOUR PHOTO] in [OUTFIT] before a concrete gallery wall, 4:5, even light. Check that no famous painting appeared, then keep the still if the room stayed empty.

💡

Pro tip: Say 'blank wall, no paintings' if you only want concrete.

Light Photo Edits

5 prompts

Window Lift Without Blowout

6/30

✨ What it does

Nano Banana lifts the dark face in [YOUR PHOTO] with fill from [FILL SIDE] and holds the window in [SETTING], keeping [OUTFIT], 4:5. Check highlight detail, then keep the relight if pores remain.

No extra person. 85mm feel. Crop 4:5. Nano Banana (Gemini image model) relight of this file, pores kept, not a new generated interior.

💡

Pro tip: Say 'hold window detail' or the glass becomes a white slab.

Rembrandt From The Upload

7/30

✨ What it does

Nano Banana relights [YOUR PHOTO] as Rembrandt from [KEY SIDE], keeps [OUTFIT] and the same room, 4:5. Confirm the triangle on the far cheek, then keep the take if the furniture is unchanged.

Overcast Flatten

8/30

✨ What it does

Nano Banana flattens hard sun on [YOUR PHOTO] to overcast while keeping [SETTING] and [OUTFIT], 3:2. Check building edges, then keep the edit if the place did not jump.

Nano Banana (Gemini image model) lighting edit of the upload, not a generated cloudy park and not a new street.

💡

Pro tip: Name a landmark in the background so the location cannot drift.

Practical Lamp Key

9/30

💡

Pro tip: If both cheeks go dark, ask for 'a white card bounce from the far side'.

Catchlight Refresh

10/30

✨ What it does

Nano Banana adds round catchlights from [LIGHT DIRECTION] on [YOUR PHOTO] without changing eye color or [OUTFIT], 1:1. Compare irises to the upload, then keep the crop if the rest of the face is still.

No extra person. Crop 1:1. Nano Banana (Gemini image model) micro-edit of this file, not a new generated beauty stare.

💡

Pro tip: One catchlight per eye. Two sources often look like studio kits you did not have.

5 prompts

Charcoal Overshirt

11/30

✨ What it does

Nano Banana swaps the outer layer in [YOUR PHOTO] for a charcoal overshirt from [OUTFIT NOTES] matching [LIGHT DIRECTION], 4:5. Check body size, then keep the edit if the cotton has real folds.

Linen Shirt Summer

12/30

💡

Pro tip: Ask for 'visible linen slub' so the cloth does not look like polyester.

Black Turtleneck Simplify

13/30

✨ What it does

Nano Banana puts a black turtleneck on the adult in [YOUR PHOTO], respects [KEEP JEWELRY], and keeps the background, 4:5. Check the neck knit, then keep the simplify if identity held.

Work Jacket Layer

14/30

Swap To A Dress Shirt

15/30

✨ What it does

Cleanup Photo Edits

5 prompts

Photobomber Fill

Nano Banana (Gemini image model) skin tidy, undetectable, not a generated porcelain face and not a makeup restyle.

💡

Logo And Sticker Lift

💡

Pro tip: List the keepers (glass, plate, notebook) or the table will go empty.

Sensor Spot Dust

20/30

✨ What it does

Nano Banana removes dust specks in [ZONE] of [YOUR PHOTO] without smoothing the adult or [OUTFIT]. Compare the sky or wall, then keep the cleanup if skin texture is untouched.

💡

Pro tip: Clone sky spots first. Running a face retouch at the same time often over-softens.

Color Photo Edits

5 prompts

Warm Kitchen Grade

21/30

✨ What it does

💡

Pro tip: Add 'keep lips and cheeks living' so cool grades do not corpse the face.

Match Brand Tile

23/30

✨ What it does

Nano Banana grades [YOUR PHOTO] toward [REFERENCE NOTES] on a 1:1 tile, keeping [OUTFIT] and furniture. Check identity, then keep the match if contrast now sits with your grid.

Grade [YOUR PHOTO] to sit on a grid with [REFERENCE NOTES] (contrast, palette words, how hard the blacks are). Keep identity, [OUTFIT] structure, furniture and the original crop intent. Crop 1:1. Nano Banana (Gemini image model) color match of this file, not a generated new campaign scene.

💡

Pro tip: Three palette words beat a long mood paragraph.

On [YOUR PHOTO], even skin a little, tidy flyaways, brighten eyes slightly, keep pores, age and [OUTFIT]. Grey or original backdrop. No extra person. 85mm. Crop 1:1. Nano Banana (Gemini image model) polish of this adult, not a generated headshot from scratch.

💡

Pro tip: Stop after one polish pass. A second pass usually over-smooths.

Open The Midtones

27/30

✨ What it does

Nano Banana lifts face midtones on [YOUR PHOTO] without clipping [BRIGHT AREA], keeping [OUTFIT], 4:5. Check the histogram in your own tool, then keep the lift if identity held.

Teeth And Eye Quiet

28/30

Pro tip: The word 'slight' matters. Default tooth work often looks like strips.

Jawline Shadow Tidy

29/30

Nano Banana softens a harsh jaw or neck shadow on [YOUR PHOTO] from [LIGHT DIRECTION] without changing face shape or [OUTFIT], 4:5. Check the jaw, then keep the tidy if the adult was not slimmed.

💡

Pro tip: Add 'do not slim the face' every time you touch a jaw shadow.

Glasses Glare Cut

30/30

✨ What it does

Nano Banana cuts glasses glare on [YOUR PHOTO] so eyes show, keeps frames unless [REMOVE GLASSES] is yes, and keeps [OUTFIT], 1:1. Confirm the irises match the upload, then keep the crop.

Frequently Asked Questions

Nano Banana is Google's Gemini image model in the Gemini app and Google AI Studio. These prompts are conversational edits on a photo you upload, not a separate product with its own chat.

No. Every job starts from [YOUR PHOTO]. You change background, light, clothes, cleanup or color on that file. If you want generation from text, use a Gemini image generation page instead.

Scope the change: keep everything the same but one thing. Restate age, hairline and pores. If identity slips, edit the last result with a smaller instruction instead of starting over.

You can, but Nano Banana often rebuilds the person when two big changes land together. Swap the room, check the face, then change the coat on that result.

No. Describe your own adult in the upload, skip famous lookalikes, skip extra invented people, and skip sexual clothing or posing. Ordinary wardrobe and rooms only.
