Use this two-step workflow: ### Step 1: Generate with Clean Background **For FLUX.1 [schnell]** (preferred for white backgrounds): ``` [Object description], isolated on pure white background, studio product photography, even diffused lighting, no shadows on background, sharp focus, high detail ``` **For FLUX.1 [dev]** (avoid "white background" - causes blur): ``` [Object description], game asset style, clear background, centered in frame, full object visible, clean edges, studio lighting, minimal shadows ``` **For Product Shots:** ``` Professional product photo of [product] on polished surface, bright studio lighting with soft shadows, clean seamless backdrop, ultra-realistic, sharp focus, high detail, minimal reflections ``` ### Step 2: Remove Background After generation, use background removal tools: - Flux Background Remover (fluxai.pro/background-remover) - Remove.bg or similar AI-powered tools - Manual masking in image editors ### Tips for Clean Cutouts - Use "game asset" in prompts for cleaner edges - Specify "full body" or "complete object visible" - Avoid complex backgrounds that bleed into subject - Request "centered in frame" for easier masking ## Photorealistic Images ### Camera & Lens References ``` Shot on [Camera Model], [focal length] lens at f/[aperture] ``` **Examples:** - `Shot on Canon 5D Mark IV, 85mm lens at f/1.8` - Portrait - `Shot on Sony A7R IV, 35mm lens at f/8` - Landscape - `Shot on Fujifilm X-T5, 50mm macro at f/2.8` - Product - `Shot on iPhone 16 Pro, wide angle` - Casual/authentic ### Lighting Descriptions - `soft diffused key light` - Even, flattering - `dramatic rim lighting` - Silhouette emphasis - `golden hour lighting` - Warm, directional - `three-point studio setup` - Professional - `high-key lighting` - Bright, minimal shadows - `low-key lighting` - Dramatic, deep shadows ### Era-Specific Styles - `2000s digicam aesthetic` - Early digital look - `80s vintage photo` - Film grain, warm tones - `Polaroid instant photo` - Square, faded edges - `35mm film photography` - Classic analog feel ## Text in Images Flux can render text accurately when properly prompted. ### Syntax ``` The text "[YOUR TEXT HERE]" appears in [style] [position] ``` ### Examples ``` A neon sign reading "OPEN 24/7" glowing in red and blue, mounted above a diner entrance at night A vintage poster with the text "JAZZ NIGHT" in bold art deco lettering, cream and gold color scheme Coffee cup with "Good Morning" written in elegant script on the ceramic surface ``` ### Text Rendering Tips - Use quotation marks around exact text - Specify font style (serif, sans-serif, script, bold) - Describe placement relative to other elements - Keep text concise - shorter phrases render better - Flux supports hex color codes: `text in #FF5733 orange` ## Artistic Styles ### Style Prompting Technique Simple "in the style of" often fails. Use this pattern: ``` [Subject], [artist/movement] art style, [technique description] ``` **Example:** ``` A sunflower field, Van Gogh art style, visible impasto brushstrokes, swirling sky, bold yellow and blue color palette, post-impressionist painting ``` ### Common Style Keywords **Illustration:** - `vector illustration, flat design, bold outlines` - `watercolor painting, soft edges, color bleeding` - `digital art, clean lines, vibrant colors` - `concept art, painterly style, atmospheric` **3D/Rendering:** - `3D render, Octane render, volumetric lighting` - `isometric illustration, clean geometry` - `low poly art, geometric facets, minimal` - `photorealistic CGI, ray tracing, subsurface scattering` **Photography Styles:** - `editorial photography, magazine quality` - `street photography, candid, documentary` - `fashion photography, high contrast, dramatic` - `architectural photography, straight lines, symmetry` **Artistic Movements:** - `art nouveau, organic curves, decorative borders` - `art deco, geometric patterns, gold accents` - `minimalist, negative space, simple composition` - `surrealist, dreamlike, impossible geometry` ## Aspect Ratios & Resolution ### Recommended Sizes | Use Case | Aspect Ratio | Resolution | |----------|--------------|------------| | Square/Profile | 1:1 | 1024x1024 | | Landscape/Web | 16:9 | 1920x1080 | | Portrait/Mobile | 9:16 | 1080x1920 | | Social Feed | 4:5 | 1080x1350 | | Print | 3:2 | 1536x1024 | | Cinematic | 21:9 | 2560x1080 | ### Resolution Guidelines - **1024x1024:** Fast, good quality baseline - **1920x1080:** Optimal quality/speed balance - **2560x1440:** Diminishing returns, longer render - **4K+:** Often blurry, not recommended for FLUX.1 ## Common Mistakes to Avoid ### Don't Use - Negative prompts (`--no`, `not`, `without`) - Flux ignores them - Weight syntax `(word:1.5)` - Not supported - "White background" in FLUX.1 [dev] - Causes blur - Overly long prompts (>500 tokens) - Gets truncated - Vague terms ("beautiful", "nice", "amazing") ### Do Instead - Describe what you want, not what to avoid - Place important words at prompt start - Use "clear background" or "game asset" for isolation - Be specific about style, lighting, composition - Use concrete descriptors over subjective ones ## Layer-Based Prompting (Complex Scenes) For detailed scenes, describe in layers: ``` BACKGROUND: Rolling hills at sunset, warm orange and pink sky MIDDLE GROUND: A rustic wooden farmhouse with smoke from chimney FOREGROUND: A winding dirt path with wildflowers on both sides ATMOSPHERE: Golden hour lighting, pastoral peaceful mood STYLE: Impressionist landscape painting, visible brushstrokes ``` ## Flux Kontext (Image Editing) For editing existing images with Flux Kontext: ### Action + Constraint Framework ``` [What to change] while [what to preserve] ``` **Examples:** ``` Change the car to bright red while keeping everything else identical Replace the background with a beach scene while maintaining the person's exact position, scale, and pose Transform the clothing to medieval armor while preserving exact facial features and expression ``` ### Kontext Tips - Be specific, not vague ("change to red" vs "make it better") - Avoid pronouns - always reference "the woman with black hair" - Work incrementally for complex edits - Kontext understands context - describe changes only ## Quick Reference Templates ### Product Photography ``` Professional product photo of [PRODUCT], centered on [SURFACE], bright studio lighting, soft shadows, clean white background, ultra-realistic, sharp focus, commercial quality ``` ### Portrait ``` Portrait of [SUBJECT DESCRIPTION], [EXPRESSION], [POSE], studio headshot, 85mm lens f/1.8, soft diffused key light, subtle rim light, neutral backdrop, natural skin ``` ### Landscape ``` [SCENE DESCRIPTION], [TIME OF DAY], [WEATHER/ATMOSPHERE], sweeping vista, shot on medium format camera, [STYLE: photorealistic/painterly/etc] ``` ### Abstract/Artistic ``` Abstract composition featuring [ELEMENTS], [COLOR PALETTE], [MOVEMENT/FLOW], [ART STYLE], museum quality fine art ``` ## Further Reading - See [references/style-gallery.md](references/style-gallery.md) for 50+ tested style prompts - See [references/product-templates.md](references/product-templates.md) for e-commerce prompts - See [references/troubleshooting.md](references/troubleshooting.md) for fixing common issues --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/code-sensei) — claim your Tome and manage your conversions.
