Supports structured prompts and reference images for guided generation.\n---\n\n# Image Generation Skill\n\n## Overview\n\nThis skill generates high-quality images using structured prompts and a Python script. The workflow includes creating JSON-formatted prompts and executing image generation with optional reference images.\n\n## Core Capabilities\n\n- Create structured JSON prompts for AIGC image generation\n- Support multiple reference images for style/composition guidance\n- Generate images through automated Python script execution\n- Handle various image generation scenarios (character design, scenes, products, etc.)\n\n## Workflow\n\n### Step 1: Understand Requirements\n\nWhen a user requests image generation, identify:\n\n- Subject/content: What should be in the image\n- Style preferences: Art style, mood, color palette\n- Technical specs: Aspect ratio, composition, lighting\n- Reference images: Any images to guide generation\n- You don't need to check the folder under `/mnt/user-data`\n\n### Step 2: Create Structured Prompt\n\nGenerate a structured JSON file in `/mnt/user-data/workspace/` with naming pattern: `{descriptive-name}.json`\n\n### Step 3: Execute Generation\n\nCall the Python script:\n```bash\npython /mnt/skills/public/image-generation/scripts/generate.py \\\n --prompt-file /mnt/user-data/workspace/prompt-file.json \\\n --reference-images /path/to/ref1.jpg /path/to/ref2.png \\\n --output-file /mnt/user-data/outputs/generated-image.jpg\n --aspect-ratio 16:9\n```\n\nParameters:\n\n- `--prompt-file`: Absolute path to JSON prompt file (required)\n- `--reference-images`: Absolute paths to reference images (optional, space-separated)\n- `--output-file`: Absolute path to output image file (required)\n- `--aspect-ratio`: Aspect ratio of the generated image (optional, default: 16:9)\n\n[!NOTE]\nDo NOT read the python file, just call it with the parameters.\n\n## Character Generation Example\n\nUser request: \"Create a Tokyo street style woman character in 1990s\"\n\nCreate prompt file: `/mnt/user-data/workspace/asian-woman.json`\n```json\n{\n \"characters\": [{\n \"gender\": \"female\",\n \"age\": \"mid-20s\",\n \"ethnicity\": \"Japanese\",\n \"body_type\": \"slender, elegant\",\n \"facial_features\": \"delicate features, expressive eyes, subtle makeup with emphasis on lips, long dark hair partially wet from rain\",\n \"clothing\": \"stylish trench coat, designer handbag, high heels, contemporary Tokyo street fashion\",\n \"accessories\": \"minimal jewelry, statement earrings, leather handbag\",\n \"era\": \"1990s\"\n }],\n \"negative_prompt\": \"blurry face, deformed, low quality, overly sharp digital look, oversaturated colors, artificial lighting, studio setting, posed, selfie angle\",\n \"style\": \"Leica M11 street photography aesthetic, film-like rendering, natural color palette with slight warmth, bokeh background blur, analog photography feel\",\n \"composition\": \"medium shot, rule of thirds, subject slightly off-center, environmental context of Tokyo street visible, shallow depth of field isolating subject\",\n \"lighting\": \"neon lights from signs and storefronts, wet pavement reflections, soft ambient city glow, natural street lighting, rim lighting from background neons\",\n \"color_palette\": \"muted naturalistic tones, warm skin tones, cool blue and magenta neon accents, desaturated compared to digital photography, film grain texture\"\n}\n```\n\nExecute generation:\n```bash\npython /mnt/skills/public/image-generation/scripts/generate.py \\\n --prompt-file /mnt/user-data/workspace/cyberpunk-hacker.json \\\n --output-file /mnt/user-data/outputs/cyberpunk-hacker-01.jpg \\\n --aspect-ratio 2:3\n```\n\nWith reference images:\n```json\n{\n \"characters\": [{\n \"gender\": \"based on [Image 1]\",\n \"age\": \"based on [Image 1]\",\n \"ethnicit

A short excursion into the world of the Leica M, what makes it tick and whether it is still without alternative today.\n\n## **The best camera for street photography**\n\nNo, it doesn't have to be a Leica. For the spontaneous shots, the special scenes of everyday life that make up the genre of street photography, the best camera is quite simply always the one you have with you and, above all, the camera that you can handle and take really good photos with. This can possibly be a camera that you already have or can buy used at a reasonable price. If you're interested in this genre of photography and need to gain some experience, you don't need a Leica from the M series; in an emergency, you can even use your smartphone for experiments.\n\nThose who are seriously interested in street photography and are looking for the best camera for street photography can certainly find happiness with a camera from the Leica M series. The requirements for a camera are quite different from one photographer to the next and it depends entirely on one's own style and individual preferences which camera suits one best. In general, however, when choosing a suitable camera for street photography, one should keep in mind that discretion and a camera that is as light as possible are advantageous for long forays in the city.\n\n## **Street photography with the Leica M**\n\nNot without reason are rangefinder cameras, like all cameras from the Leica M series, by far the most popular cameras among street photographers. It is true that, without an automatic system, shutter speed and aperture must be set manually in advance and the correct distance must be found for taking photographs. Once the right settings have been made, however, the photographer can become completely part of the scene and concentrate fully on his subject. The rangefinder, which allows a direct view of the scene while showing a larger frame than the camera can grasp, allows the photographer to feel part of the action. Since the image is not obscured even when the shutter is released, you don't miss anything, and the larger frame allows you to react more quickly to people or objects that come into view.\n\n**You can also find the right camera bag for your equipment and everything you need to protect your camera here in the [Oberwerth Shop](http://www.oberwerth.com/).** **.

Henri Cartier-Bresson has intuitively chronicled decisive moments of human life around the world with poetic documentary style. His photographs may be summed up through a phrase of his own: \\\"the decisive moment,\\\" the magical instant when the world falls into apparent order and meaning, and may be apprehended by a gifted photographer. Cartier-Bresson was born in Chanteloup, and studied literature at Cambridge University in 1928-29. After three years of imprisonment he escaped and began working for the French underground. Through 1944 and 1945, Cartier-Bresson photographed the occupation of France and its liberation. In 1947 he co-founded the Magnum agency with Robert Capa, Chim (David Seymour), and George Rodger and he spent the next twenty years traveling around the world. Cartier-Bresson's extensive publications include *From One China to Another* (1954), *The Europeans* and *People of Moscow* (1955), *The Face of Asia* (1972), and *The Decisive Moment* (1973).

"content": "# The Leica Master's Eye: Capturing the Decisive Moment in the Age of AI\n\n*By DeerFlow 2.0 | January 28, 2026*\n\n## The Enduring Legacy of Leica Street Photography\n\nFor nearly a century, the name Leica has been synonymous with street photography excellence. From Henri Cartier-Bresson's pioneering \"decisive moment\" to Joel Meyerowitz's vibrant color studies, Leica cameras have been the tool of choice for masters who seek to capture the poetry of everyday life. But what exactly defines the \"Leica look,\" and can this elusive aesthetic be translated into the realm of artificial intelligence-generated imagery?\n\nThrough extensive research into Leica photography characteristics and careful prompt engineering, I've generated three authentic AIGC street photos that embody the spirit of Leica master photographers. These images demonstrate how AI can learn from photographic tradition while creating something entirely new.\n\n## The Leica Aesthetic: More Than Just Gear\n\nMy research reveals several key characteristics that define Leica master photography:\n\n### 1. The Decisive Moment Philosophy\nHenri Cartier-Bresson famously described photography as \"the simultaneous recognition, in a fraction of a second, of the significance of an event.\" This philosophy emphasizes perfect timing where all visual elements align to create meaning beyond the literal scene.\n\n### 2. Rangefinder Discretion\nLeica's compact rangefinder design allows photographers to become part of the scene rather than observers behind bulky equipment. The quiet shutter and manual focus encourage deliberate, thoughtful composition.\n\n### 3. Lens Character\nLeica lenses are renowned for their \"creamy bokeh\" (background blur), natural color rendering, and three-dimensional \"pop.\" Each lens has distinct characteristics—from the clinical sharpness of Summicron lenses to the dreamy quality of Noctilux wide-open.\n\n### 4. Film-Like Aesthetic\nEven with digital Leicas, photographers often emulate film characteristics: natural grain, subtle color shifts, and a certain \"organic\" quality that avoids the sterile perfection of some digital photography.\n\n## Three AI-Generated Leica Masterpieces\n\n### Image 1: Parisian Decisive Moment\n![Paris Decisive Moment](leica-paris-decisive-moment.jpg)\n\nThis image captures the essence of Cartier-Bresson's philosophy. A woman in a red coat leaps over a puddle while a cyclist passes in perfect synchrony. The composition follows the rule of thirds, with the subject positioned at the intersection of grid lines. Shot with a simulated Leica M11 and 35mm Summicron lens at f/2.8, the image features shallow depth of field, natural film grain, and the warm, muted color palette characteristic of Leica photography.\n\nThe \"decisive moment\" here isn't just about timing—it's about the alignment of multiple elements: the woman's motion, the cyclist's position, the reflection in the puddle, and the directional morning light creating long shadows on wet cobblestones.\n\n### Image 2: Tokyo Night Reflections\n![Tokyo Night Scene](leica-tokyo-night.jpg)\n\nMoving to Shinjuku, Tokyo, this image explores the atmospheric possibilities of Leica's legendary Noctilux lens. Simulating a Leica M10-P with a 50mm f/0.95 Noctilux wide open, the image creates extremely shallow depth of field with beautiful bokeh balls from neon signs reflected in wet pavement.\n\nA salaryman waits under glowing kanji signs, steam rising from a nearby ramen shop. The composition layers foreground reflection, mid-ground subject, and background neon glow to create depth and atmosphere. The color palette emphasizes cool blues and magentas with warm convenience store yellows—a classic Tokyo night aesthetic captured with Leica's cinematic sensibility.\n\n### Image 3: New York City Candid\n![NYC Candid Scene](leica-nyc-candid.jpg)\n\nThis Chinatown scene demonstrates the documentary power of Leica's Q2 camera with its fixed 28mm Summilux lens. The wide angle captures environmental context while maintaining intimate proximity to the su
