Hyper-curvy Gym Selfie Prompt Json | HowToWritePrompt

A structured Image Generation prompt optimized for midjourney. Utilizes a 85mm optical perspective and Rembrandt 3-point studio lighting with 45° key light and soft fill bounce to produce crisp, high-detail results without artificial smoothing.

Master Prompt Template
{ “subject”: { “description”: “A vertical mirror selfie photograph taken in a dimly lit gym, featuring two young women with long dark hair posing closely together.”, “body”: { “physique”: “Both women possess extremely exaggerated, hyper-curvaceous ‘slim-thick’ fitness physiques. They have very small, defined waists that transition sharply into massively accentuated, round, and prominent glutes and shapely thighs. This dramatic hourglass shape is the central focus of the image, highlighted by the tight clothing and pose.”, “pose”: “The woman on the right holds a silver smartphone (with stickers) in her right hand to take the mirror selfie, angling her body slightly and looking at the phone. The woman on the left stands in a sharp side-profile next to her, aggressively arching her lower back to maximize the projection of her glutes towards the mirror, looking back over her left shoulder.”, “features”: “Both have long, dark, straight hair falling over their shoulders/backs. Their facial features are similar.” } }, “wardrobe”: { “outfit”: “The woman on the left wears a black sports bra and tight, dark grey seamless ‘scrunch-butt’ gym leggings. The woman on the right wears a black sports bra with cleavage strap details and tight, solid black seamless ‘scrunch-butt’ gym leggings.” }, “pose_action”: “Taking a double mirror selfie in a gym, specifically posing to highlight their glutes.”, “scene”: { “environment”: “A modern commercial gym environment, likely at night.”, “elements”: “The background is filled with various gym equipment with grey metal frames, large mirrors reflecting other areas of the gym, and distinct warm yellow LED strip lighting on the ceiling. Other blurred gym patrons are visible in the background reflections.”, “composition”: “Vertical 9:16 aspect ratio full-body mirror selfie.” }, “lighting”: { “setup”: “Mix of functional artificial gym lighting and warm ceiling accent strips.”, “details”: “The lighting creates highlights on the tight fabric of the seamless leggings, emphasizing the contours of their bodies.” }, “camera”: { “technical”: “High-resolution smartphone mirror selfie photograph. Sharp focus on the two women’s reflection. Realistic textures of spandex and gym equipment.”, “aspect_ratio”: “9:16”, “constraints”: [ “CRITICAL: The subjects MUST have the exact exaggerated, hyper-curvy gym physique with tiny waists and massive glutes as explicitly described.”, “CRITICAL: The specific poses (one holding phone, one arching side-profile) and outfits (grey vs. black leggings) must be replicated exactly.”, “The final image must be a photorealistic vertical 9:16 photograph.” ] } }, 85mm telephoto lens compression with creamy background bokeh, captured on Leica M11 with Summilux-M 50mm f/1.4 ASPH lens, Soft overcast diffused daylight through a north-facing studio window, authentic skin micro-textures, true-to-life surface physics, ultra-detailed editorial photography, Straight-on symmetrical frontal angle, captured on 70-200mm telephoto compressed lens, Rembrandt 3-point studio lighting with 45° key light and soft fill bounce, natural surface physics, 8K ultra-detailed editorial photography --ar 9:16 --v 6.1 --style raw

- **Framing & Shot Type**: Wide environmental establishing shot (Straight-on symmetrical frontal angle)
- **Optics & Focal Intent**: 70-200mm telephoto compressed lens at f/2.8 balanced subject sharpness with soft background bokeh
- **Lighting Atmosphere**: Rembrandt 3-point studio lighting with 45° key light and soft fill bounce
- **Color Grading**: Clean high-key commercial color grade with vibrant true-to-life tones
- **Model Constraints**: Preserves natural skin texture; avoids oversaturated smoothing.

💡 **How To Customize**: Replace `{SUBJECT}` with your exact character or scene, or switch the Aspect Ratio to `9:16` for mobile reels and wallpaper formats.
