Best Practices

最佳实践

Choosing Scale Factor

选择放大比例

  • 2x: Sufficient for most web and social media use cases
  • 4x: Standard for print quality (300 DPI equivalent)
  • 8x+: Only for large format where viewing distance is greater
  • 2倍：满足大多数网页和社交媒体场景需求
  • 4倍：印刷质量的标准选择（等效300 DPI）
  • 8倍及以上：仅适用于观看距离较远的大幅面场景

Quality Tips

质量提升技巧

  • Source Quality Matters: Higher quality input produces better upscaled output
  • File Format: Use PNG or high-quality JPEG (90%+) as input when possible
  • Face Enhancement: Enable only for images with human faces
  • Noise Reduction: Use aggressively for low-light or heavily compressed images
  • 原图质量很重要：输入图片质量越高，放大后的输出效果越好
  • 文件格式：尽可能使用PNG或高质量JPEG（90%以上）作为输入
  • 人脸增强：仅在包含人脸的图片中启用
  • 降噪处理：在低光或严重压缩的图片中使用高强度降噪

Output Considerations

输出注意事项

  • File Size: Higher scale factors produce significantly larger files
  • Processing Time: 8x and 16x upscaling takes longer - be patient
  • Viewing Distance: Large format prints are viewed from distance; extreme detail isn't always necessary
  • 文件大小：放大比例越高，生成的文件体积越大
  • 处理时间：8倍和16倍放大耗时更长，请耐心等待
  • 观看距离：大幅面印刷品是远距离观看的，并非始终需要极致细节

Prompt Tips for Image Upscaling

图片放大提示词技巧

When requesting upscaling, include these details in your prompt:
  1. Scale Factor: Specify 2x, 4x, 8x, or 16x
  2. Use Case: Web, print, large format display
  3. Image Type: Photo, AI art, product shot, portrait
  4. Special Requirements: Face enhancement, noise reduction, artifact removal
  5. Output Intent: Final use case helps optimize processing
请求放大时，请在提示词中包含以下细节：
  1. 放大比例：指定2倍、4倍、8倍或16倍
  2. 应用场景：网页、印刷、大幅面显示屏
  3. 图片类型：照片、AI艺术作品、商品图、肖像
  4. 特殊需求：人脸增强、降噪、失真去除
  5. 输出用途：明确最终使用场景有助于优化处理效果

Example Prompt Structure

提示词结构示例

"Upscale this [image type] [scale factor] for [use case].
[Special requirements like face enhancement or noise reduction].
[Additional context about the source image quality or intended output]."
"将这张[图片类型]放大[比例]，用于[应用场景]。
[特殊需求，如人脸增强或降噪]。
[关于原图质量或预期输出的额外说明]。"

Mode Selection
