If you're familiar with the process of utilizing frequency separation in your retouching workflow, then you're probably aware – and frustrated by – the lack of total control and somewhat average results you get while using it. While the method remains a skin retouching staple, the core approach to setting it up in Photoshop has been more or less the same for a while now, and accepted as such.
The basic premise of frequency separation is creating the ability in Photoshop to manipulate the base colors and textures separately, thus giving you the control to perfect skin tone without obliterating skin texture. On paper, this sounds to good to be true. For many retouchers, the discovery of this method is initially exciting, and then eventually discouraging due to the limitations of the classic frequency separation setup process.

Then add in the workflow slowdowns while processing the filters and other functions involved in the setup, and frequency separation becomes a necessary evil, perhaps, but one that leaves you feeling a little flat about your results.
But what if you could have a bit more control, all in one panel, and achieve better results? Perhaps you have higher demands in your retouching, and are always looking to step it up. Accepting and implementing what everyone else does is only going to get you so far. This is where Freqsep Control comes in.
