Biometric six-pack ID photos

@dotey dropped a Nano Banana prompt that automates the entire ID photo workflow. It first calls up official requirements for each country and document type, then runs Gemini 3 Pro in Nano Banana to output six perfectly matched head-and-shoulder shots arranged on a 6x4-inch sheet so you can hand the file straight to a photo lab or home printer without retouching anything.

Prompt

Generate an ultra-realistic personal ID photo for [Document Type], precisely replicating all facial features from the uploaded photograph without any beautification, editing, or alterations, strictly complying with official standards for the specified document.
Step 1: Retrieve or request the official photo guidelines based on user-selected country and [Document Type] (e.g., passport, ID card, visa, driver's license, student card). Capture: Background Color (default solid white), Facial Position (face forward, head centered from crown to chin), Expression (neutral, eyes open facing camera), Eyewear (no glasses unless medically required with reflection-free lenses), Accessories Restrictions (no hats/headscarves/headphones unless religious), Photo Dimensions (e.g., 2 x 2 inches; provided by user or fetched automatically).
Step 2: Generate the photo strictly following the guidelines: subject faces directly forward, expression calm and neutral, mouth gently closed, both ears visible, shoulders fully captured. Use professional, soft, evenly balanced front lighting with zero harsh shadows; match the specified background color exactly. Composition must keep head and shoulders centered and proportioned per the official rules. Finally, deliver 6 identical ID photos arranged vertically in a 2x3 grid on one 6x4-inch print-ready sheet with a light grey background, uniform spacing, and high resolution ready for printing. -- Document Type: US Visa

Recommended settings

  • Gemini 3 Pro • biometric ID workflow
  • Nano Banana document compliance pipeline
  • 6x4 inch 2x3 grid export

Execution notes

  • Have the model fetch the document policy first so background, expression, and crop stay compliant before rendering.
  • Ending the brief with a 2x3 grid requirement produces a ready-to-print sheet for visa or passport submissions.
