Usage Recommendations

Prompt Best Practices

1. Be Specific: Describe desired content and style in detail

   Example: "A professional product photo of a sleek black smartphone on a marble surface,
         with soft studio lighting and shallow depth of field"
   

2. Specify Style: Clearly state the required artistic style

   Example: "in the style of modern minimalist photography"
        "cinematic lighting, 4K quality"
   

3. Detail Description: Include important details and attributes

   Example: "warm color palette, golden hour lighting, subtle film grain"
   

Common Techniques

• Weight Control: Use descriptive words to emphasize important elements
• Negative Prompts: While Flux.1 Pro has high default quality, some platforms allow specifying content to avoid
• Resolution Settings: Choose appropriate output resolution based on use case
• Batch Generation: Generate multiple variants to select the best result

Technical Specifications

• Output Formats: PNG, JPEG
• Maximum Resolution: Supports up to 2048x2048 pixels (some platforms support higher)
• Generation Speed: Typically 10-30 seconds (depending on resolution and platform)
• Prompt Length: Supports longer descriptive prompts

Limitations

1. Content Policy: Follows strict content policies, prohibits generating inappropriate content
2. Commercial Use: Pro version allows commercial use, but must comply with terms of service
3. Generation Consistency: Cannot guarantee identical results across multiple generations
4. Portrait Restrictions: Does not generate portraits of real public figures
