BeforeAfter
Before: the sample photo. After: made with Nano Banana Pro from this exact prompt. The sample photo is AI-generated.

What each part of the prompt does

Identity line first
The prompt opens with "keep the face exactly the same" before any scene detail, so the model locks the face before it starts inventing clothes and streets. Put it later and you tend to get a stranger in a good costume.
Period wardrobe
Flared trousers, a wide-collar patterned shirt and aviators "pushed up on the head" are three cues that read as 1970s at a glance. Sunglasses on the head also keep the eyes visible, which helps likeness.
Street props
The pale blue scooter, painted shop signs and the black and yellow taxi place the scene in Bombay rather than any old city. Naming the taxi colours stops Gemini drawing a modern yellow cab.
Film look and frame
"Faded 1970s colour photo look, warm tones, slight grain" ages the image like a print from a family album, and "4:5 frame" gives a tall crop that fits an Instagram feed.

Variations to try

Same idea, one thing changed. These have no example image yet.

  • Marine Drive seafront

    Using my uploaded photo, keep the face exactly the same and place the person on Marine Drive in 1970s Bombay. They lean against a pale blue vintage scooter parked by the sea wall, wearing flared trousers, a patterned shirt with a wide collar and aviator sunglasses pushed up on the head. The curved seafront, the grey-blue Arabian Sea and a black and yellow taxi passing behind them fill the background. Faded 1970s colour photo look, warm tones, slight grain, 4:5 frame.

  • 1980s instead of 1970s

    Using my uploaded photo, keep the face exactly the same and place the person in a 1980s Bombay street scene. They lean against a red vintage motorcycle, wearing high-waisted jeans, a denim jacket over a printed T-shirt and large square sunglasses pushed up on the head. Hand-painted film posters, a black and yellow taxi and people in 1980s clothes fill the background. Saturated 1980s colour photo look, soft flash, slight grain, 4:5 frame.

  • Safari suit

    Using my uploaded photo, keep the face exactly the same and place the person in a 1970s Bombay street scene. They lean against a pale blue vintage scooter, wearing a beige short-sleeved safari suit with a belt and aviator sunglasses pushed up on the head. Old painted shop signs, a black and yellow taxi and people in period clothes fill the background. Faded 1970s colour photo look, warm tones, slight grain, 4:5 frame.

If the result isn't right

  • If the face comes back looking like a generic actor, reply in the same chat: "The face has changed. Use the exact face from my photo and redo only the face."
  • Gemini sometimes slips in modern details such as mobile phones or LED shop signs; type "remove anything made after 1979" to strip them out.
  • When the result looks too clean and digital, ask for "more fading, a slight yellow colour shift and visible grain, like a scanned family print".
  • If the scooter turns into a motorbike, describe it more closely: "a pale blue classic step-through scooter with a curved front shield".
