A powerful retouching technique. Separating the skin's tone from its texture, allows for realistic retouching.
Frequency Separation is the virtual process of decomposing of a images data into separate frequencies, so that we can edit image details in frequencies independently. There can be any number of frequencies in each image, and each frequency will contain certain information. Typically, we break down the information data in our images into high (texture) and low (tones & color) frequencies.
Use Frequency Separation to make your retouching a lot faster, easier and more natural looking results.
