Gemini Photo Editing Prompt Guide

The formula behind the prompts on Hixa — so you can adapt them or write your own.

Updated

The 5-part formula

Good edit prompts answer five questions in order: 1) What must stay the same (face, expression, body)? 2) What is the subject wearing? 3) Where are they? 4) What is the light? 5) What camera and format? Example: "Keep my face and expression exactly the same. Dress me in a black chiffon saree with silver jhumkas. Place me on a Mumbai rooftop at dusk. Soft golden-hour backlight with warm rim light. Shot on an 85mm lens, shallow depth of field, 4:5."

Face-lock phrases that work

"Keep the face 100% identical to the uploaded photo", "do not alter facial features, skin tone or expression", "maintain exact identity". Put this at the start of the prompt — models weigh early instructions more.

Lighting words that change everything

Golden hour, blue hour, direct on-camera flash, window light, rim light, neon backlight, overcast soft light. Pick one main light source; mixing several produces flat images.

Camera words for realism

Lens (35mm, 50mm, 85mm), depth of field (shallow, f/1.8), film stock (Kodak Portra 400), device (iPhone, disposable camera) and grain. These cues push the model away from the glossy "AI look".

FAQ

How long should a Gemini prompt be?

For photo edits, 60–200 words is the sweet spot: long enough to describe face-lock, outfit, place and light, short enough that nothing gets ignored.
