Frequency separation is a technique used to separate the different frequency components of an image. This can be useful for retouching images, as it allows you to work on the different frequency layers separately. There are a number of ways to do this in Photoshop, but one of the most popular is to use an action.
To create a frequency separation action, you first need to create two new layers. On the first layer, apply a high pass filter to the image.
This will remove the low frequency components from the image, leaving only the high frequencies. On the second layer, apply a low pass filter. This will remove the high frequency components, leaving only the low frequencies.
PRO TIP: Frequency separation is a technique in Photoshop that is used to separate the textures in an image from the colors. This can be useful for retouching photos, as it allows you to make changes to the texture without affecting the color. However, it is important to be careful when using this technique, as it can easily lead to over-processed photos.
You can then work on each of these layers separately. For example, if you want to remove wrinkles from an image, you would work on the low frequency layer.
If you want to sharpen an image, you would work on the high frequency layer. Once you have finished working on each layer, you can merge them back together to create a final image.
Conclusion:
Frequency separation is a powerful tool that can be used for retouching images in Photoshop. By separating the high and low frequencies into separate layers, you can work on each independently and then merge them back together for a final result.

Frequency separation retouching is a technique used to split an image into two separate layers in Photoshop – one layer containing the high frequencies (details and textures), and the other layer containing the low frequencies (larger areas of color and tone). The high frequency layer is then edited first, and the low frequency layer is left untouched. This preserves the overall skin tone and color while still allowing you to make Targeted adjustments to the details and textures.
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 technique used in Photoshop to separate the high frequency detail from the low frequency color information in an image. This allows for more Targeted editing of each layer, which can lead to more realistic results. The basic idea behind frequency separation is that the human eye is more sensitive to changes in brightness than changes in color.
