In Photoshop, frequency separation is a technique used to separate two different types of image information: low-frequency information that includes things like color and overall tone, and high-frequency information that includes things like skin texture and individual hairs. By separating these two types of information, you can make changes to one without affecting the other.
For example, you could use frequency separation to smooth out skin texture without affecting the overall skin tone.
Frequency separation is a fairly simple technique that involves creating two separate copies of your image, one for the low frequencies and one for the high frequencies. You then apply a blur to the low-frequency copy and a sharpen to the high-frequency copy.
The two copies are then combined, with the low-frequency copy on top and the high-frequency copy on bottom. By using different layer blend modes, you can control how the two copies interact with each other.
There are a few things to keep in mind when using frequency separation. First, it’s important to use a gentle blur on the low-frequency copy and a gentle sharpen on the high-frequency copy.
Second, you’ll need to experiment with different layer blend modes to find the one that works best for your image. And finally, frequency separation is not a panacea – it won’t fix every problem with your image. But it can be a helpful tool in your Photoshop toolbox.
However, frequency separation can also be used to create images that look unnatural, or that have artifacts that are difficult to remove. If you are not careful, you may end up with an image that looks worse than it did before you started.
If you are going to use frequency separation, be sure to read tutorials and understand how the technique works before you start. Otherwise, you may end up with an unusable image.
