Google Nano Banana 2 Prompt: { "aspect_ratio": "9:16", "prompt": "Photorealistic bathroom mirror scene of the same woman (exact face reference from uploaded photo, preserve every facial feature, skin texture, pores, natural imperfections, no beautification or smoothing) standing in front of a large rectangular bathroom mirror, brushing her teeth with a white electric toothbrush in her right hand. Framed to show her full face and upper shoulders clearly in the mirror reflection, looking straight at her reflection in the mirror with a neutral/relaxed expression, slight foam at the corners of mouth from toothpaste. Mouth slightly open during brushing motion, toothbrush angled naturally against teeth. Shot from the viewer's perspective as if standing behind her looking into the mirror (mirror reflection composition), eye-level framing. Bright even bathroom lighting from overhead LED fixtures (cool-white 4000-5000K) plus soft warm vanity lights around the mirror edges, creating realistic skin highlights, subtle shadows under chin, natural eye catchlights, authentic wet-look shine on lips/teeth from toothpaste/foam. Medium-length chestnut brown hair loosely tied back in a messy low ponytail or bun, a few loose strands framing face. Wearing a simple light gray cotton t-shirt or basic crew-neck top, fully clothed, modest coverage. Delicate fine-line tattoo visible on right forearm if present in reference. Foreground details: modern white porcelain sink with chrome faucet/tap running slightly (small stream of water visible), toothbrush charger on counter, tube of white toothpaste open nearby, marble or white tiled countertop with minor water spots for realism. Background softly blurred: tiled bathroom wall in light neutral tones, shower curtain or glass door faintly visible behind. Ultra-sharp focus on face/reflection, hyper-photorealistic skin details (visible pores, subtle redness, natural texture, light oil sheen on forehead), candid everyday smartphone or point-and-shoot photo aesthetic, natural color grading, high dynamic range, no artificial glow, no over-sharpening, believable depth of field with creamy bokeh on background.", "negative_prompt": "blurry, deformed face, changed facial features, plastic skin, beauty filter, airbrushed, doll-like, heavy makeup, exaggerated symmetry, bad hands, extra fingers, warped mirror reflection, text, watermark, logo, oversaturated, cartoonish, 3D render, low quality, jpeg artifacts, noise, night time, dim lighting, suggestive pose, exposed skin beyond normal casual, no selfie hand/phone visible", "style": "hyper-photorealistic, candid bathroom mirror everyday moment", "quality": "high-resolution, ultra-detailed skin pores/hair/texture/foam details" }

Creative Blueprint & Recipe Breakdown

How to Master & Adapt This Visual

Professional prompts rely on modular tokens. Use this recipe breakdown to swap subjects, control studio lighting, and eliminate common AI artifacts.

Prompt Variables Blueprint (What to Customize First)

Iterate on one variable group at a time to maintain stylistic consistency:

1Change the subject block first: { "aspect_ratio": "9:16", "prompt": "Photorealistic bathroom mirror scene of the same woman (exact face reference from...
2Adjust the mood through light and backdrop cues: Bright even bathroom lighting from overhead LED fixtures (cool-white 4000-5000K) plus soft warm vanity lights around the...
3Keep the finish constraints aligned while you test variants: Ultra-sharp focus on face/reflection, hyper-photorealistic skin details (visible pores, subtle redness, natural texture,...

3 Style Recipes

Swap the subject, keep the frameRecipe #1

Replace { "aspect_ratio": "9:16", "prompt": "photorealistic bathroom mirror scene of the same... with your own subject while leaving the camera and composition cues intact.

Retune the mood, not the structureRecipe #2

Keep the subject block, then rewrite bright even bathroom lighting from overhead led fixtures (cool-white 4000-5000k) plus... to move the image into a new lighting setup.

Change the finish without breaking geometryRecipe #3

Test a new texture or rendering finish by rewriting ultra-sharp focus on face/reflection, hyper-photorealistic skin details (visible pores,... while leaving the scene structure alone.

Production Quality Guide: Best Use vs. Pitfalls

Ideal Use Cases (Where it Shines)
  • •Portrait studies, beauty concepts, and tightly framed editorial references.
  • •Reference-image workflows where identity, product shape, or silhouette should survive the restyle.
  • •Realism-heavy outputs where believable materials, skin, or product finishes need to hold up in close view.
  • ✓Start with a sharp reference image. This prompt is written to preserve source identity, silhouette, or product structure before stylization.
  • ✓Use 9:16 on the first run, then test alternate crops after the base composition is working.
  • ✓This prompt suppresses text or logos. Remove that constraint before asking for branded packaging, typography, or visible watermarks.
Pitfalls to Avoid (Common Mistakes)
  • !Ignoring the recommended 9:16 crop on the first run. The prompt's composition cues were written for that frame.
  • !Using a muddy reference image and expecting the prompt to repair identity, silhouette, or packaging structure on its own.
  • !Asking for readable type, logos, or packaging text without first removing the no-text constraint.
  • ✕Skip if: You need a wide environment shot or multiple subjects competing for attention in the same frame.
  • ✕Skip if: You need to begin with a radically different crop than 9:16 instead of honoring the existing composition hints.
  • ✕Skip if: Your reference image is low-resolution, badly lit, or cluttered enough to break subject preservation.
