How to Use Brother-Sister Prompts

Open Gemini’s image-generation feature and paste a prompt into the chat box. You can ask for a photorealistic photograph, cartoon illustration, watercolour painting, vintage photograph, cinematic image, or festive portrait.

A useful prompt structure is:

Create a [type of image] of a brother and sister [activity] in [location]. The brother is wearing [outfit], and the sister is wearing [outfit]. Add [props or decorations]. Use [lighting], [mood], [photography style], and [aspect ratio].

For example:

The brother is wearing a light-blue shirt and beige trousers, and the sister is wearing a pastel dress. Add natural smiles, soft sunlight, gentle background blur, and a vertical 4:5 composition.

For editing a real sibling photograph, use an instruction such as:
