The Concept Of Frequency Separation In Professional Picture Editing

Professional Picture Editing
Frequency Separation Concept

Frequency separation is a technique that has been doing the rounds in photo retouching services for while now. Often, the technique is misunderstood by amateur photographers who try to retouch the skin in Photoshop going in vain. In frequency separation, editors isolate the main details of an image from the colors as well as the tones, in order to retouch both details separately. The main benefit of frequency separation is that the editors can easily retain the details especially when doing in-depth professional picture editing and thereby have better control over color and tone.

Editors work on duplicate layers to separate spatial frequency data on an image uploaded in Photoshop. All the in-depth edits are done on the high copy layer. Editors use high copy layer as a backup so that if something goes wrong while retouching spatial frequency data, they can use that layer to retouch again.

Luminosity layer lets professional picture editing services adjust the color and tones. However, editors will not always rely on frequency separation to retouch each and every image. For instance, if the skin is perfect, the technique may lead to extreme luminance and plastic-like skin tone with less realism.

When retouching the skin, editors will consider the aim their client has set for themselves. For instance, if the aim is to beautify the skin, editors will strive to achieve luminance which client desires with the Lasso tool. Editors select an area on the image using the Lasso tool and then will blur the same area using the Gaussian blur filter in Photoshop. Gaussian blur will give the effect of smoothing the transition between color and tone giving editors control.

Control Over Color And Tone

Using Gaussian blur filter, professional picture editing services easily render the luminance skin tone which may look less realistic when luminance become extreme. The Gaussian blur filter may also create the blurry skin provided editors use low opacity only.

Some clients desire the plastic-skin for their online portals containing fashion photos, headshots of models, whereas other clients prefer blurry skin for wedding portraits. This is why editors rely on dodge and burn layers, which gives more flexibility while retouching the luminosity of an image.

As of now, these are the overriding concepts that are driving most editors indulged in skin retouching with frequency separation.
