# Wavelet Sharpen

Razor sharp images.

Wavelet Sharpening lets you sharpen an image at different scales. That means you can sharpen details of different sizes independently. It is a very fast and powerful way to bring out the details in your photos. In more detail, the image is broken down into different wavelet bands. Each band corresponds to a detail size. The wavelet bands (detail sizes) can be sharpened independently and then recombined back to produce a sharpened image.
