A reusable 6-part template for any prompt for Gemini AI

Use this structure every time you write a prompt for Gemini AI:

1. Subject and Identity - who or what is the focus (reference photo or product).
2. Action and Pose - what the subject is doing.
3. Scene and Context - environment, background, composition.
4. Style and Lens - era, mood, medium, film grain, lens feel.
5. Lighting and Color - time of day, key light, palette.
6. Constraints and Consistency - what must remain the same across variations.

Copy starter (paste into Gemini and attach a face or product reference):

"Create a photoreal portrait of the same woman from the reference image, standing on a rain-slick city street at dusk, shallow depth of field, soft golden practical lights in the background, subtle film grain, 85mm lens feel. Keep facial features, hairstyle, and jewelry consistent. Warm key light from camera left; muted, moody palette. Generate two variations with identical subject identity."

Keeping identity and constraints explicit helps Gemini preserve likeness as you iterate the same prompt for Gemini AI across a set.

Pro tips to sharpen your prompt for Gemini AI

• Use references plus text together. Upload a face or product reference and pair it with a precise prompt for Gemini AI so the model can fuse semantics with visuals.
• Annotate what to change. When you only need a regional edit, such as a logo fix or background cleanup, state it clearly in your prompt for Gemini AI and keep a do-not-change list.
• Iterate with variants. Save a baseline prompt for Gemini AI and spin three to five controlled variants. Change pose or lighting, while keeping identity and palette fixed.
• Think omnichannel. If you plan to move from stills to short motion with Veo 3 or similar tools, mirror the look and feel defined in the still-image prompt for Gemini AI.
• Stay trend-aware and brand-true. Trend prompts can boost reach, but translate them into your brand vocabulary so each prompt for Gemini AI remains authentic.
