Application Guide
Create stylized character figures
Let's explore how to generate collectible figure-style artwork using FLUX Dev.
Example Prompt Structure:
| Prompt ：“Anime-style collectible figure of a blue-haired girl in a school uniform, displayed inside a clear acrylic display case with LED base lighting. 1/7 scale PVC figurine with long twin-tails, black jacket, white shirt, and pleated skirt. Dynamic pose on a translucent blue effect base. Studio photography, product shot on a white background, softbox lighting, high detail, professional product photography.” |
|---|
If you want to generate a more detailed image, you can try the higher quality advanced prompt words.
Advanced Prompt for Maximum Quality:
| Prompt ："Premium Japanese anime figure, magical girl character with flowing pink twin-tails, ornate battle dress with metallic accents, holding crystalline staff, mid-action pose on hexagonal display base, LED effects highlighting translucent parts, 1/6 scale figure in display case, professional figure photography, depth of field, Canon 5D Mark IV, 85mm lens, product showcase lighting" |
|---|
This “figurine-style” generation scenario addresses users’ needs for creativity, personalized expression, and collectible transformation. It also enhances the value of sharing and showcasing on social platforms, combining creativity, practicality, and emotional engagement to deliver a more immersive user experience.
Environmental Concept Art
Example Prompt Structure:
| Prompt ："Cyberpunk cityscape, neon-lit streets, flying vehicles, rain-slicked pavement reflecting lights, towering holographic advertisements, atmospheric fog, cinematic composition, concept art style, detailed architecture, moody lighting" |
|---|
Let me try to further optimize the prompt words.
Advanced Prompt for Maximum Quality:
| Prompt ："Futuristic Tokyo street level, dense urban environment, multilayered architecture with bridges and walkways, neon signs in Japanese and English, crowded marketplace below, flying delivery drones, volumetric lighting through fog, blade runner aesthetic, detailed environmental storytelling, professional concept art, digital painting style" |
|---|
The model's speed allows artists to generate dozens of variations in minutes, rapidly exploring different moods, compositions, and color palettes. This makes it ideal for pre-production phases, client presentations, and creative brainstorming sessions.
High-Fashion Editorial Photography
Example Prompt Structure:
| Prompt ："High fashion editorial portrait, model wearing avant-garde structured blazer with geometric cutouts, dramatic shadow play, shot by Annie Leibovitz for Vogue, Hasselblad H6D-100c, natural window light, minimalist studio setting " |
|---|
Let's go a step further.
Advanced Prompt for Maximum Quality:
| Prompt ："Luxury fashion campaign, ethereal white silk gown with intricate embroidery, model in motion creating fabric flow, golden hour backlight through sheer curtains, shot in Château de Versailles, medium format film aesthetic, editorial styling by Grace Coddington, dreamy atmospheric mood, professional retouching, high-end fashion photography " |
|---|
The model demonstrates a sophisticated understanding of complex art direction, style references, and technical photography terminology, translating nuanced creative visions into stunning visuals. This approach generates magazine-ready images with professional lighting, composition, and post-processing aesthetics that rival actual fashion photography shoots.
Children's Book Illustration
FLUX Dev excels at creating consistent, charming illustrations perfect for children's literature:
Example Prompt Structure:
| Prompt ："Watercolor illustration for children's book: friendly purple dragon wearing a yellow raincoat and red boots, splashing in puddles in a magical forest, soft pastel colors, whimsical style, white background with subtle texture, cheerful expression" |
|---|
Optimization Techniques:
● Specify art medium (watercolor, digital, pencil)
● Include mood descriptors (whimsical, cheerful, cozy)
● Define color palette explicitly
● Request consistent character features
Example Prompt Structure:
| Prompt ："Children's book illustration series: Scene 1: Small bear cub with blue scarf discovering a glowing acorn in autumn forest, warm orange leaves falling, soft morning light Scene 2: Same bear cub sharing the magical acorn with forest friends (rabbit, owl, squirrel), sitting in circle under large oak tree Scene 3: Bear cub and friends planting the acorn together, rainbow appearing in background, celebrating with joy Style: Gentle watercolor with soft edges, storybook illustration, warm and inviting colors, consistent character design throughout" |
|---|
The model's consistency ensures characters remain recognizable across multiple illustrations, while its understanding of artistic styles creates cohesive visual narratives perfect for publishing.
Advanced Publishing-Ready Prompt:
| Prompt ："Professional children's book double-page spread: Left page: Young astronaut mouse in detailed spacesuit floating near colorful planet Right page: Same mouse landing on planet surface meeting friendly alien creatures Art style: Modern digital illustration with texture overlays, vibrant but not oversaturated colors, dynamic composition, age 4-8 target audience, print-ready quality with bleed considerations" |
|---|
This level of control, along with noticeable image stylization, makes FLUX Dev ideal for professional publishing projects that require specific layouts and consistent character representation.
Best Practices with FLUX Dev
● Be Specific: The more detailed the prompt, the closer the result.
● Iterate & Refine: Generate first, then adjust with instructions like “make the lighting warmer” or “change to night scene.”
● Use Photographic Terms: Terms like “35mm lens, cinematic lighting” enhance realism.
● Layered Prompts: Build complex scenes step by step (background → subject → details).
● Research Extensions: Leverage open weights for fine-tuning, style transfer, or domain-specific adaptation.
