Frequently Asked Questions
What is the difference between sharpening types?
Basic Sharpen enhances overall details. Unsharp Mask provides professional control with radius and threshold. Edge Sharpen targets only edges. Clarity enhances mid-tone contrast. Structure brings out fine textures.
When should I use Unsharp Mask?
Use Unsharp Mask for professional sharpening when you need precise control. It's perfect for portraits, landscapes, and product photography where you want to enhance details without creating halos.
What does Clarity adjustment do?
Clarity enhances mid-tone contrast, adding depth and texture to your photos. Positive values add punch and definition, while negative values create soft, dreamy effects. It doesn't affect pure whites or blacks.
How much sharpening is too much?
Over-sharpening creates halos, noise, and unnatural edges. Start with low values (50-150) and gradually increase. Use the preview to check for halos around high-contrast edges. Stop before you see obvious halos.
Can sharpening fix blurry photos?
Sharpening can improve slightly soft or out-of-focus photos, but cannot fix severely blurred images. It enhances existing detail rather than creating missing information. Results vary based on the original image quality.
What is the threshold parameter in Unsharp Mask?
Threshold determines which edges get sharpened. Lower values (0-30) sharpen more edges including subtle ones. Higher values (100-200) only sharpen strong edges, reducing noise amplification.
Is it safe to use this sharpen tool?
Absolutely. All processing happens directly in your browser using JavaScript. Your images are never uploaded to our servers, ensuring complete privacy and security.
