Nano banana portrait prompts are structured text instructions that tell Gemini/nano-banana-style models exactly how to render a face: subject, lighting, camera, style, and aspect ratio. The prompts below are ready to copy, paste, and adapt—each includes concrete details so the model has less room to guess.
Nano banana models respond well to portrait work because they handle skin texture, eye detail, and hair strands without over-smoothing. But they still need direction. A prompt that says "beautiful woman, soft light" produces generic output. A prompt that says "35mm portrait, f/1.8, Rembrandt lighting, catchlights in both eyes, visible pores, 4:5 aspect ratio" gives the model a target. This guide gives you that level of specificity across realistic, stylized, and cinematic portraits.
How to structure a nano banana portrait prompt
A reliable nano banana portrait prompt has six parts, in this order:
- Subject — age, gender, expression, pose, wardrobe.
- Lighting — source, direction, quality (soft/hard), color temperature.
- Camera — lens, aperture, distance, angle.
- Style — photorealistic, editorial, painterly, cinematic.
- Texture — skin, hair, fabric details.
- Aspect ratio — 4:5 for portraits, 1:1 for headshots, 9:16 for vertical.
For a deeper breakdown of each part, see the prompt structure and syntax guide and the portrait styles guide.
Why order matters
Nano banana models weight early tokens more heavily. Put the subject first, then lighting, then camera. If you put style first, the model may lock onto a look and ignore facial details. If you put camera last, you may get a great composition with flat lighting.
Realistic nano banana portrait prompts
These prompts aim for photos you could pass off as camera captures. They specify lens, aperture, and skin texture.
Natural window light headshot
"Portrait of a 32-year-old woman with freckles and shoulder-length auburn hair, neutral expression, facing camera, wearing a linen shirt. Soft window light from camera left, 5600K, gentle falloff on the right cheek. 85mm lens, f/2.0, chest-up framing, eye-level angle. Photorealistic, visible pores, fine hair strands, catchlights in both eyes. 4:5 aspect ratio."
Golden hour outdoor portrait
"Portrait of a 28-year-old man with short dark hair and a light beard, slight smile, looking off-camera to the right, wearing a denim jacket. Golden hour backlight, sun 15 degrees above horizon, warm rim light on hair and shoulders, soft fill from a reflector. 50mm lens, f/1.8, waist-up framing, slight low angle.

Stylized nano banana portrait prompts
Nano banana models handle style transfer well when you name the style and keep the subject description tight.
Oil painting portrait
"Portrait of a 60-year-old man with a white beard, serious expression, wearing a wool coat. Oil painting style, visible brushstrokes, impasto texture, warm earth palette, chiaroscuro lighting. 3/4 view, bust framing. 4:5 aspect ratio."

Cinematic nano banana portrait prompts
Cinematic portraits use film-like color grading, shallow depth of field, and often a narrative context.
Film still portrait
"Portrait of a 35-year-old detective with a tired expression, wearing a trench coat and tie. Cinematic film still, teal and orange color grade, anamorphic lens flare, shallow depth of field. 40mm lens, f/1.4, medium close-up, eye-level.

Low-key lighting: single softbox at 90 degrees camera right, deep shadows, background falls to black. 85mm lens, f/2.8, head-and-shoulders framing, slight high angle. Photorealistic, visible skin texture, subtle rim light on hair. 4:5 aspect ratio."

Common mistakes and fixes
Mistake 1: Too few details
"Beautiful woman" gives you a random face. Add age, hair, expression, wardrobe, and pose.
Mistake 2: Conflicting lighting
Don't mix "golden hour" with "studio softbox." Pick one source and describe direction and quality.
Mistake 3: Ignoring aspect ratio
Portraits work best in 4:5 or 1:1. If you need vertical for social, use 9:16 and adjust framing to full-body or waist-up.
Mistake 4: Overloading style
One style is enough. "Oil painting, anime, cyberpunk" produces mud. Choose one and commit.
For more on avoiding conflicts, see negative prompts guide.
How to adapt these prompts
Change one variable at a time. Start with the subject, then adjust lighting, then camera. If the face looks too smooth, add "visible pores, skin texture, no retouching." If the lighting is flat, specify direction and quality. If the background distracts, add "plain dark background" or "blurred background."
For more control, see portrait poses and composition guide and portrait expressions and emotions control.
Nano banana 2 and future models
Nano banana 2 improves on skin texture and lighting consistency. The same prompt structure works, but you can push detail further. For example, add "subsurface scattering" for more realistic skin, or "anamorphic bokeh" for cinematic depth. See nano banana 2 prompts for more.
