I02 — An empty room, staged, at dusk, and listed

An empty apartment photographs badly: white walls, a bare floor, nothing to make a buyer imagine living there. Furnishing it for a shoot costs days; showing it at dusk, with the fire lit, costs another visit. And whatever is done, a listing has one rule that must never bend: the room in the picture must be the room that is for sale.

This example furnishes the room and lights it for the evening without moving a wall, a window or a floorboard, then builds everything the listing needs in the agency’s look — and checks the one part that must work in the reader’s hand, the QR code, before it is delivered.

The exact graph is the workflow (as a diagram).

The case

An agency lists a four-room apartment in a nineteenth-century building. The agent sends one photo of the living room, empty; the furniture partner provides photos of two pieces — a gilded armchair and a painted vase.

Input	Who provides it	Reference run
Empty Room Photo	the agent	the living room, herringbone parquet, a window, a fireplace, 1376 × 768
Armchair, Vase	the furniture partner	product photos on grey
Listing Headline	the agent	Haussmann apartment · 4 rooms · 112 m²
Price	the agent	€ 890,000
Listing Link	the website	https://example.com/listings/rue-claire-4
Agency Mark	the agency	its mark, an SVG

What it shows

• The photograph is kept; only what is asked is added. The staging step is Image Transform with the room as the first picture and the furniture after it, and an instruction that starts with what must not change — camera, perspective, framing, walls, window, fireplace, floor, light. The armchair arrives by the window at the room’s scale and light, the vase on the mantelpiece; the room is the agent’s photo.
• Two moments from one photo. The dusk picture is the staged room with only its light changed: blue hour in the window, the fire and the lamps lit — the photo an agent waits for an evening to take.
• A layout that is exact every time. The listing photo, the before-and-after, the flyer and the social post are deterministic steps: Resize, Text on Image in the agency’s fonts and colours, Overlay for the mark, Stack, Extend Canvas for the QR’s place — the same look on every listing of the agency.
• A code that is proved to work. The QR code to the listing is drawn with the agency’s mark in its centre and read back by the step before it is returned: the run reports scanned: true, matches: true (Layouts, batches and codes).

The workflow, step by step

Phase	Steps	What they do here
A — stage	A1 Stage the Room	Image Transform on Nano Banana 2 Edit with three pictures — room, armchair, vase — and aspect_ratio: match_input, so the frame is the photo’s
B — dusk	B1 The Same Room at Dusk	Image Transform on the staged room: only the light changes
C — listing pack	C1 Mark at 110 px, C2 Listing Photo 1600 px, C3 Headline on the Photo, C4 Price on the Photo, C5 Agency Mark	the staged room at 1600 × 900 with the headline and the price on the free floor, the mark top right
	C6–C8 Before and After	the empty room and the dusk room side by side
	C9 QR to the Listing, C10 QR at 300 px	QR Code & Barcode from the link, rounded modules in the agency’s green, the mark in the centre; read back
	C11–C15 Flyer	the listing photo over the before-and-after, extended with room at the bottom for the QR and a call to action composed from the price
	C16 Social Post at Dusk	Resize for Platform, Instagram square

The reference run

Output	Result
staged_room, dusk_room	1376 × 768, the agent’s frame
listing_photo	1600 × 900, headline, price and mark
before_after	1600 × 439
flyer	1720 × 1819
qr_code, qr_check	an SVG; read back, matches the link
social_post	1080 × 1080, the room at dusk — full size

10 credits: 5 to furnish, 5 for dusk; the whole pack 0.

Honest staging

A staged photo is a promise. Keep it:

• Start from the photo and add to it. Here Image Transform gets the room first and each piece after it, so several pieces go in at once; for one piece, Showroom Visualizer with room_image does the same — it keeps the room as photographed and adds the product.
• Say what must not change before what to add, and compare the result with the photo: walls, windows, doors, floor.
• Label it. Many markets require staged or retouched pictures to say so; a line of Text on Image — “Virtually staged” — is one more step at no cost.

Adapt it

• Every room. Run the workflow once per room — the facts stay, the photo and the furniture change — or over a list of rooms with an iteration.
• Other furniture. Add pictures after the room (images_3, images_4…) and name them in the instruction; the default model reads up to 14.
• Other channels. Portals and social networks each get a Resize for Platform step, free.
