The DxO ClearView (Dehaze on other software) is a special treatment for landscapes that boosts contrasts to remove the atmospheric veil and blurs the mist.
It is available with the Elite Edition of PhotoLab, in global correction and Local Adjustment.

PhotoLab offers an exclusive treatment which is a concentrate of MicroContrast accentuation coupled with an increase in color saturation.
Once again, this is not a recipe dosed with traditional sliders but an analysis of the image coupled with a specific treatment using particular algorithms.
It is not possible to reproduce the effect of Clear View by combining various traditional corrections.

* The Clearview does most of its work on dark pixels contained in the light and medium areas.
  By restoring deeper blacks, it adds contrast to the image and liveliness to colors.
* It is dependent on the brightness; exposure compensation and selective tone settings
* Color rendering is often a bit cold
* It easily gives a dramatic atmosphere to the images by increasing the contrast and saturation.
* For DxO, like other editors, the default settings on this type of function are a little forced to show the effect. On a landscape, values of 10 to 20 are generally sufficient for a subtle effect.

I myself do not systematically activate ClearView in my preset when opening photos, to appreciate the effect when it’s applied.

* Prefer to use it for Local Adjustments, to modulate its effect according to the elements in the image. Do not apply it to foregrounds, for example.
* Always try to use it at the minimum power necessary, and prefer to increase the fine contrast slightly (FilmPack license).

* In my own preset the ClearView is inactive in order to appreciate its effect when I judge its application.
* It is prepositioned to 15 by default. I then activate it by Right-Clicking on the right-hand part of the rail so that it is set to the starting value of 20.

See the tutorial “Efficiency with PhotoLab – Presets

The ClearView must be activated before using the tools of the “Contrast” palette in order to have the desired rendering right away. Do not hesitate to use both corrections at the same time.

Some busy users use the ClearView to adjust contrast, microcontrast and saturation with a single slider. This is an mistake that causes you to lose control of the overall correction and increases the risk of artifacts.

Clearview has been improved in version 4 of PhotoLab to give more natural and pleasing results with subtle details. DxO calls this version 2 “Clearview Plus” without allowing access to the first version (like PRIME for example). This adverb makes the name unnecessarily cumbersome.

The ClearView to give character to an image  
The application of the ClearView gives a portrait some hardness. Apart from this effect the ClearView is generally not recommended for this purpose.
On this image with a chilly atmosphere, it was the means to give this chiseled atmosphere that freezes.

Compensating for the excess of Clearview
For this image of a red kite on the hunt, which is a bit soft at first, 
Selective tone: highlights -40, midtones +60, shadows +20,
The ClearView processing is very strong: +70
Yet the values are consistent. The subject is the bird that it is important to highlight by ensuring the consistency of the image.

The ClearView as a local adjustment mask 
In a populated landscape like this one, the animals are too saturated by the ClearView.
– Do not use the ClearView on the global image
– Use a gradient filter (Local Adjustments) to densify the sky and another for the sea

Neutralize the color change  
The ClearView has enhanced this image, but has distorted the shade of the metallic blues and lost the bronze mirror look.
– Then use the desaturation of the blues in the HSL Adjustment
