Gemini AI Photo Prompts: How to Write Them
Gemini AI photo prompts work best when they are long and specific: Google's image models in the Nano Banana family keep track of many conditions and can combine several uploaded photos in one picture.

On MarketVideo you reach these models through Create photo, and many catalog templates are written for them. Open a card below to read a working example, or paste your own detailed text and attach the pictures it refers to.
Write long, but in a fixed order
Where many models drop conditions after the third or fourth, Gemini keeps going. List them in a steady sequence: subject, material, surroundings, light source and its direction, camera angle, palette, mood. The 3×3 Product Campaign Grid template shows the scale it handles: nine separate concepts, one per cell, with the same product in each.
Give each uploaded image a job
With several pictures attached, say what each one contributes: the person from the first, the setting from the second, the colors from the third. Showing is often quicker than describing. Cosmos in Your Eyes works this way, taking two photos of irises and keeping their real color and pattern in a single composition.
Ask for texture by name
Left alone, Gemini leans toward a clean, slightly polished look. If you want grain or roughness, write it plainly: skin with visible pores and no smoothing, rough paper with visible fibers, film grain. Portrait templates such as Luxe Portrait in White spell out real skin texture and a fully recognizable face for the same reason.
Prompts for men, products and photo edits
The same structure covers every subject. For a man's portrait, fix the medium, background and composition, as Half Sketch, Half Real does for any face. For editing, state what changes and what stays: Lime Splash Product Visual keeps the jar completely unchanged and builds only the scene around it.
When another model fits better
Gemini's image line is not the answer to everything. For lettering on packaging, GPT Image 2.5 is often more accurate; for bold artistic styling, try Seedream 4.5. The model is picked before the run, so the same text can be tried on several of them and compared, keeping in mind that each attempt spends stars.

FAQ
Can I copy and paste a Gemini prompt?
Yes. Paste it into the text field on Create photo, choose a Nano Banana model and attach any photos the prompt mentions. If it says the person from my photo, the upload must show you or a person who consented.
How many images can one Gemini prompt use?
Several at once is fine. What matters more than the count is that the text names a role for each image, such as the face from one and the room from another, so the model does not have to guess.
Is a very long prompt worth it?
Mostly yes. Gemini holds more conditions than most models, but a list without order still loses details. Group related points, cut repeated words, and if something is ignored, move it closer to the start and run again.
What does running a prompt cost?
Generations use stars. A newly registered account receives five after the email address is verified, and each model displays its price in stars ahead of time. Larger balances are bought on the Pricing page.
