How to use
A watercolour portrait turns your photo into a delicate painting, with thinned pigment bleeding into the paper, soft spatters and the white reserved for the light. This prompt recreates that hand-painted effect while preserving your face, and it works in Gemini, NanoBanana and ChatGPT.
1. Pick a sharp photo of yourself, ideally with your face well lit.
2. Send the image in the same message where you are going to paste the prompt.
3. Paste the full JSON prompt right below your photo.
4. Repeat in your request that your features must be kept completely, changing only the technique to watercolour.
5. Generate two or three variations and choose the one that is most faithful and most beautiful.
6. Save it in high resolution to print and frame as a picture.
Tip: in the technique field you control how strong the spatters and the bleeding are, making the painting looser or more contained.
