Nano Banana Pro Prompt Tips for Portraits, Products and Posters

Image models reward specific, visual prompts. These tips come from patterns we see across the Nano Banana Pro prompts in the Pavo AI prompt library.

Portraits

Name the framing (close-up, half-body), the light (soft window light, rim light), the lens feel (85mm, shallow depth of field) and one or two texture details such as skin, fabric or hair. Skip long lists of adjectives.

Product photos

Say what the product is, the surface it sits on, the background colour and the light direction. Add “clean studio shot” or “lifestyle scene” to choose between a catalogue image and an in-context one.

Posters and infographics

Write the layout like a brief: title position, number of sections, colour palette and the exact text to show in quotation marks. Short text renders more reliably than long paragraphs.

Editing your own photo

Upload a reference image and describe only the change: “keep the face and pose, change the outfit to a navy suit and the background to a city street at dusk”.

Iterate in small steps

Change one thing per run — light, angle or background — so you can tell what helped. When you find a result you like, save the prompt and reuse it with a new subject.
