How to use
How about a detective pet portrait, straight out of a 1940s film noir? This prompt creates the black and white scene full of mystery. Send your pet's photo along with the JSON prompt in the same message, in Gemini, NanoBanana or ChatGPT, and the AI puts on the fedora and the trench coat while preserving your animal's breed, fur colour and markings.
1. Choose a sharp photo of your pet, face forward and with good light.
2. Paste the full JSON prompt in the same message where you attach the photo.
3. Stress that the AI must keep the breed and the muzzle markings under the hat and the coat.
4. Generate variations by choosing between pure black and white or a light sepia tone.
5. Download the version that looks most like your pet in high resolution.
Remember the costume only exists in the image: in real life, use light, comfortable accessories only, and for a short time.
