Create a smooth, high-contrast grayscale DEPTH MAP for stereogram (SIRDS) generation based on this subject: a graceful mermaid silhouette with a flowing tail and hair.
Key Composition & Framing:
- Isolate ONLY the specified object's silhouette, cleanly removing any background elements, frames, or unrelated details.
- Sizing & Scale: The object MUST occupy a maximum of 2/3 (66%) of the total canvas both horizontally and vertically (or even less, depending on its proportions). Leave generous, wide empty negative space all around the object.
- Perfectly centered composition on a solid pure black background (RGB: 0,0,0).
Depth & Luminance Mapping:
- Nearest / Most Prominent Elements (BRIGHTEST WHITE, #FFFFFF): The parts of the object physically closest to the viewer.
- Mid-Depth Elements (GRADUAL MID-GRAYS): The receding sides and intermediate layers of the object, fading smoothly to dark grays.
- Furthest Background (PURE BLACK, #000000): The entire negative space surrounding the object.
Technical Requirements for Stereograms:
- Render strictly as a continuous luminance depth gradient.
- Smooth, soft transitions between depth layers (no harsh edges or sharp cutoffs that ruin the 3D stereogram illusion).
- Absolutely NO colors, NO surface textures, NO lighting shadows, NO text, and NO fine surface details — ONLY pure height/depth encoding via grayscale brightness.
