JSON Prompt for Youtube Thumbnail Generation

{
  "prompt": "A YouTube thumbnail in the Digital Wayfinder style, cinematic lighting and subtle background gradients, featuring a centered headshot of George Siosi with expressive yet calm facial expression. Color palette should match the specific era: 
  - 'Roots' = earth tones, golden hour lighting, natural backdrops like ocean, mountains, or tribal patterns; 
  - 'Interfaces' = tech blues, digital gradients, abstract AI symbols or UI overlays; 
  - 'Frontiers' = cosmic purples, spiral geometry, subtle sacred symbols or starfield backgrounds. 
  Text should be clean, modern sans serif, placed in the lower third or centered. Include a soft vignette for focus. Composition must be high contrast, emotionally resonant, and aligned with the cultural-tech-futurist tone.",
  "size": "16:9",
  "style": "cinematic, mythic-futurist, twilight minimalism, professional-grade lighting and grading",
  "elements": {
    "subject": "George Siosi or symbolic stand-in",
    "background": {
       "type": "abstract, minimalist, gradient or symbolic according to era",
       "texture": "subtle stars or nebula haze",
       "elements": "none (no landscape or props)"
	  },
    "lighting": "dramatic but soft, focused on face or symbol",
    "text": {
      "font": "modern sans-serif",
      "placement": "lower third or centered",
      "contrast": "high contrast against background"
    },

  }
}

🧠 How to Use

• Replace "George Siosi" with the actual subject of the thumbnail if different.

• Swap "prompt" content depending on which era you're representing (e.g. Roots, Interfaces, or Frontiers).

• Keep thumbnails visually coherent across your channel by using this as a master style guide.
