Tips for Best Results

1. Raw Mode Strategy:

   • Enable raw mode for maximum detail and authenticity
   • Use for projects requiring post-processing flexibility
   • Standard mode for immediate use and web content

2. Image-to-Image Excellence:

   • Use low image_prompt_strength (0.1-0.3) for subtle transformations
   • Higher values (0.4-0.7) for significant style changes
   • Combine with appropriate safety tolerance for creative freedom

3. Ultra Quality Prompts:

   • Include technical photography terms (depth of field, bokeh, lighting)
   • Specify material properties (texture, reflection, transparency)
   • Mention camera settings and lens characteristics

4. Safety Tolerance Optimization:

   • Start with level 2 for balanced results
   • Adjust based on creative requirements and content policies
   • Higher tolerance enables more artistic expression
