Frequency Separation Made Easy
To put it as easily as possible, frequency separation is a Photoshop technique which separates the texture of an image from its shape creating two layers, one storing color and luminosity information and the other one, storing the detail. Activating a curve adjustment layer, restricted to operate on the high frequency layer, you can change the detail level of the image by steepening or flattening the curve. You will also be able to easily clone over defective parts with no visible side-effects.
What’s new in Wow! Frequency Equalizer Pro Vs Classic
Wow! Classic works on five different frequency layers, but where are they? Well, they’re hidden: you actually manipulate them with the sliders, but there’s nothing else you can do. Wow! Pro adds the option to turn each frequency into its own pixel layers. You can paint, clone and heal on the very exact frequency layer that contains the features you need to target, with great precision, giving you unprecedented control over the retouching process.
