FAQ

Will the sharpen filter create noise in photos?

Moderate sharpening generally won't create noticeable noise, but excessive sharpening may cause noise at edges. It is recommended to choose appropriate intensity based on photo quality.

What types of photos are not suitable for sharpening?

Photos with high noise are not suitable for sharpening as sharpening will also enhance noise. It is recommended to denoise first, then sharpen.

Can I sharpen multiple times?

Yes, but it is recommended to use moderately. Over-sharpening can cause image distortion and unnatural appearance.
