Frequently Asked Questions
What's the difference between structure sharpen and regular sharpen?
Structure sharpen is more sophisticated than regular sharpen. It works on multiple levels - enhancing fine details, improving local contrast, defining structures, and sharpening textures separately, rather than just applying a uniform sharpening effect.
Which sharpening method should I use?
Use Adaptive Structure for most images as it adapts to content. Choose Multi-scale for landscapes with varied details, High Pass for technical precision, or Unsharp Mask for classic sharpening control.
How do I avoid over-sharpening?
Start with lower strength values (30-50%), use appropriate threshold levels, enable shadow/highlight protection, and use the Edge Only mode for targeted enhancement. Monitor the preview closely.
What's the difference between Detail, Structure, and Texture?
Detail enhances fine elements like hair and fabric, Structure improves overall form and shapes, while Texture brings out surface characteristics like wood grain or skin texture.
Should I use Luminance Only mode?
Use Luminance Only when you want to enhance details without affecting color saturation. This is ideal for portraits and when you want to maintain natural color reproduction.
