Prompt
A photo of a small bedroom split exactly down the middle by a clean vertical line: the left side is 1975, with orange flowered wallpaper, a shag rug and a rotary phone and the right side is 2025, with white walls, a low platform bed and a smart speaker, in the same room from the same camera angle. Furniture positions line up across the split so the two halves read as one space. Natural daylight, realistic interior photography.

Scene prompt guide
How the scene is composed
A small bedroom split down the middle by a clean vertical line, with one half in 1975 featuring orange flowered wallpaper and a rotary phone and the other half in 2025 with white walls and a low platform bed, is what Nano Banana 2.1 makes from this prompt. It works because both halves share one camera angle and aligned furniture, so the eye reads a single room changing across time. Natural daylight and realistic interior photography keep the result believable.
- Scene and split line
A photo of a small bedroom split exactly down the middle by a clean vertical line
This sets the room and the one hard edge that divides it. Without the clean vertical line the image turns into a mixed-up room, so the split reads as a deliberate design choice.
- 1975 side details
the left side is 1975, with orange flowered wallpaper, a shag rug and a rotary phone
These items set the 1975 mood with orange flowered wallpaper, a shag rug and a rotary phone. Remove the shag rug or the phone and the left half loses its era cues, so it looks like any older room.
- 2025 side details
the right side is 2025, with white walls, a low platform bed and a smart speaker
The 2025 side uses white walls, a low platform bed and a smart speaker to signal today. Changing the bed to a tall four-poster would shift the era read, while keeping the low platform bed keeps the contrast clear.
- Shared camera view
in the same room from the same camera angle.
This phrase locks the camera so both halves are photographed from one spot. Delete it and the model may shift the viewpoint between sides, which breaks the sense of one room.
- Alignment and light
Furniture positions line up across the split so the two halves read as one space. Natural daylight, realistic interior photography.
This line-up rule keeps the furniture at matching depths across the split, so the two halves read as one room. Natural daylight and realistic interior photography give a plain, believable look that suits a real-estate style shot.
Camera and light
The prompt sets one camera position and one kind of daylight, so the camera and light do most of the work here. Small changes to these two notes shift the mood without changing the split.
- Camera
- The phrase 'from the same camera angle' fixes one viewpoint for both halves, which is what makes them read as one room. To change the view, name a height and direction, such as 'from a higher camera angle above the doorway', and keep it the same on both sides.
- Light
- Natural daylight gives soft, even light with gentle shadows, which keeps the colors true. For more drama, replace it with 'soft window light from the left' so the shag rug and bed get a clear shadow edge.
- Scale
- The small bedroom keeps every object close together, so a bed or phone that looks too big is noticed quickly. Add 'a low platform bed sized for a small room' if the furniture overwhelms the frame.
- Split line
- The clean vertical line is the one hard edge in the image and carries the whole idea. Adding 'thin, straight line down the center' makes it crisper, while removing it turns the image into two unrelated rooms.
Variations on the scene
Evening lamplight
Swaps the daylight for warm evening lamplight, so the orange wallpaper glows and the room feels cozier.
Prompt
A photo of a small bedroom split exactly down the middle by a clean vertical line: the left side is 1975, with orange flowered wallpaper, a shag rug and a rotary phone and the right side is 2025, with white walls, a low platform bed and a smart speaker, in the same room from the same camera angle. Furniture positions line up across the split so the two halves read as one space. Warm evening lamplight, realistic interior photography.
Higher camera angle
Moves the camera higher to look down across both halves, useful when you want the full floor and furniture alignment visible.
Prompt
A photo of a small bedroom split exactly down the middle by a clean vertical line: the left side is 1975, with orange flowered wallpaper, a shag rug and a rotary phone and the right side is 2025, with white walls, a low platform bed and a smart speaker, in the same room from a higher camera angle above the doorway. Furniture positions line up across the split so the two halves read as one space. Natural daylight, realistic interior photography.
Kitchen split instead
Keeps the same split and structure but swaps the bedroom for a kitchen, useful when you want a 1975 versus 2025 comparison in a different room.
Prompt
A photo of a small kitchen split exactly down the middle by a clean vertical line: the left side is 1975, with avocado green cabinets, a checkered floor and a wall-mounted phone and the right side is 2025, with white flat-front cabinets, an induction cooktop and a smart speaker, in the same room from the same camera angle. Cabinet positions line up across the split so the two halves read as one space. Natural daylight, realistic interior photography.
Model and settings
Keep the 3:2 ratio, since its wide frame gives both halves of the room enough space to show their details. Keep 1k for quick tests of the split and the furniture alignment, then raise the resolution once the layout looks right. This is a text-to-image prompt, so no input picture is needed; switch to image edit only if you want to restyle a room photo you already have. For a tall phone-style image, change the ratio, but check that the split line still sits in the center.
- Nano Banana ProPick Nano Banana Pro when the furniture alignment across the split matters most, since its tagline says it plans the layout first. That planning helps keep the bed, rug and phone in matching positions on both sides.
- Seedream 5.0 ProPick Seedream 5.0 Pro if you have reference photos of a real 1975 room and a real 2025 room, since its tagline promises high detail from up to ten references. That lets you match the actual wallpaper and furniture rather than relying on words alone.
When the scene falls apart
- Extra furniture fills the room, so the 1975 and 2025 details get lost in a cluttered frame.
- Add 'uncluttered, with open floor space' after the camera angle sentence, or delete any object not named in the prompt.
- The model paints the orange wallpaper or white walls past the split line, so the two eras blur together.
- Add 'the wallpaper stops at the vertical line' to the first sentence so the boundary is explicit.
- Flat light makes both halves look equally grey, so the 1975 colors lose their punch.
- Replace 'Natural daylight' with 'soft window light from the left' to give the two halves some shape.
- The years 1975 and 2025 come out as printed text or signs on the wall.
- Add 'no text, no labels, no signs' at the end of the prompt.
Questions about this scene prompt
How do I keep the split line straight in a Nano Banana 2.1 room image?
The prompt already asks for a clean vertical line and one camera angle, which gives the model a clear brief. If the line bends or drifts, regenerate and check that the wall corners and floor edge match on both sides before you use the image.
Do I need to upload a photo of a real bedroom to make this split image?
No, this is a text-to-image prompt, so Nano Banana 2.1 builds both eras from the words alone. Upload a room photo only if you want to edit an existing room, because the split effect works from the description.
Why does the 1975 side sometimes look like it has modern objects in it?
Nano Banana 2.1 can blend era details, so a smart speaker or modern lamp may drift into the 1975 half. Name the left side's objects again, for example 'no modern objects on the left side', to keep the decade clean.
