Duo Tone Portrait Nano Banana prompt example

Nano Banana prompt text

A creative, high-contrast studio portrait capturing a female figure in an intimate close-up with a mysterious and introspective atmosphere. The subject is posed with her head tilted slightly downward, her gaze directed toward the ground, just outside the frame, conveying a sense of deep contemplation. The most striking feature of the image is the dramatic lighting with dual-colored gels. One side of the face and body is bathed in vibrant cyan or teal light, while the opposite side is illuminated by contrasting red or magenta light. This creates a sharp color division in the center of the figure, sculpting the facial features with colorful highlights and deep shadows. She wears a simple black top with a low neckline, which allows the colored light to play across the skin of her décolleté and shoulders. Her makeup is defined, with eyeliner accentuating her eyes and lips with a subtle, light-catching gloss. The hair is long, straight, and dark, falling softly over the shoulders and framing the face, the strands capturing the reflections of the colored lights. The background is completely black and uniform, ensuring that all the focus remains on the subject and the vibrant play of light. Camera Settings: Captured with a prime portrait lens (e.g., 85mm or 100mm) on a full-frame camera for a sharp, distortion-free close-up. Aperture set between f/2.8 and f/4.0 to keep the face in sharp focus with a shallow depth of field. ISO 100-200 for maximum image quality, free of noise. Shutter speed from 1/160s to 1/250s. Lighting is key: two studio light sources (strobes or continuous lights) with colored gels (cyan and red) positioned on opposite sides of the subject to create a split-light effect, without using fill light to maximize contrast. Instructions for the "nano banana": "Please use the user's reference image to capture and apply all of their facial features, facial structure, eye color, skin tone, and hair style, color, and texture with maximum fidelity. The goal is to create a version of the user in this artistic portrait. The pose (head tilted down), the dramatic dual-gel lighting (cyan and red), the black top, and the dark background should be created as described, creating a seamless fusion between the user's identity and the modern, colorful aesthetic of the image."

Prompt workflow

How to use this Nano Banana prompt

Start with the full prompt so its subject, scene, and visual direction stay connected. Then adapt only the part that changes your result: the subject for a new concept, the scene for a different setting, or the style and composition for a new format.

Preserve the core brief

Keep the subject, visual style, and composition cues that make this prompt recognizable. Change one creative variable at a time when iterating.

Match the output to the channel

Choose the aspect ratio for the final placement, then add a clear crop, camera, or layout instruction instead of relying on a vague style word.

Use references for hard-to-name details

Upload references when a product shape, material, palette, or composition is easier to show than to describe in words.

Refine with a specific goal

Ask for a concrete change such as a different background, lighting direction, framing, or text treatment while naming the details that must remain.

Use this prompt with other image models

This remains a Nano Banana prompt first. Use these alternatives when the same brief needs a different kind of image control.

Nano Banana prompt FAQ

How should I adapt this prompt?

Keep the strongest subject, scene, and style instructions, then make one targeted change for the result you need. Clear changes are easier to evaluate than replacing the whole prompt at once.

When should I use a reference image?

Use a reference when you need to preserve a visual detail that text alone may not capture, such as a product silhouette, a material, a color palette, or a composition.

Which model should I choose?

Start with Nano Banana for fast iteration. Choose GPT Image 2 for text-heavy or precise edit requests, and Flux 2 Pro when detailed commercial art direction or multiple references matter most.
