Processing an image with DxO PhotoLab Essential Edition


Photo taken on the dam of Petten in the Netherlands in the afternoon

A- Automatic application of the "DxO Standard" preset

The "DxO Standard" preset is applied by default.
The parameters of all available tools are judiciously adjusted according to the
shooting conditions (optics used, diaphragm, light and ISO speed).

DxO PhotoLab makes the most of your photos especially if
the optic module (Camera + Lens) has been calibrated by DxO.
Processing photos in raw format is highly recommended.

The relevant tools are activated (Windows: white square / Mac OS X: blue square)
In addition to the "Essential Tools" palette settings
with the "1- DxO Standard" preset, DxO PhotoLab :

* Adjusts lens Sharpness to maximize sharpness results
* Suppresses Chromatic Aberrations
* Corrects Vignetting depending on the diaphragm used
Corrects Lens Distortions
* Protects saturated colors avoiding flattened areas 

When opening the photo, DxO already offers a relevant solution to the image.

B- Recreate the original image atmosphere

DxO PhotoLab brings a global solution to the image while
specifically treating the different areas according to their illumination.

The "Essential Tools" palette offers the basic tools for processing the photo.

Adjustments are needed:
* Either for restoring the atmosphere of the shooting that DxO PhotoLab
   cannot guess
* Or for customizing your image according to your desire

Use the tools in this palette from the top to the bottom.

White Balance: Nothing to do in full summer sun > Original

Exposure Compensation
The photo is slightly underexposed > Recover by 0.3 LI

DxO Smart Lighting: This exclusive feature of DxO PhotoLab analyzes the image (brightness and contrast) to balance the global tone over the entire available dynamic range.
SmartLighting lightens the shadows by preserving bright areas and retrieves details in clipped areas. The default is the "Uniform" option.

The scene being brightly lit, the subject is still too dark.

Spot Weighted: This option automatically detects faces, but Spot Weighted can be applied to any area of the subject.
- Activate the selection tool (illustration)
- Draw a square on the too-dark
man > Select mode Medium

Selective Tone: This function adjusts the SmartLighting corrections to create the atmosphere of the scene.
The sky lacks density > Highlights -20
The rendering of stones, black tillite, is too bright > Blacks -20

Contrast: For this camera + lens used, DxO uses a module measured by the laboratory.
The MicroContrast magic wand
proposes 16

Color Accentuation:
The very bright afternoon sky lacks saturation  > Vibrance +40
This menu, rather than Saturation, is specially designed to act only on the dominant colors of nature, blue and green.

Noise Reduction: DxO Standard preset activates it from the beginning.
DxO PhotoLab knows the camera, the selected sensitivity and the lighting of the scene will automatically apply an optimized noise treatment to the areas that need it.

C- Improve the image

Horizon: A horizontal dam would strengthen the image >

- Click on the "Horizon"
tool in the upper bar (illustration)
   Ignore the blue line proposed by default for a more efficient method.
- Left Click determines the first point (1)
- Hold the click while crossing to the second point (2)
- Release

Cropping: DxO PhotoLab automatically selects the whole image.

The image corresponds to the original atmosphere of the shot.

D- Take ownership of the image

The foreground is too present.
The clear silhouette of the man helps make adjustments.

Local Adjustments:
Foreground paving stones must be blurred
> Graduated Filter, Blur

- Launch the "Local Adjustments" tool in the upper bar (illustration)
- Right Click: Select Graduated Filter (A)
- Left Click on the bottom of the image (1)
- Holding the click while crossing to the third of the image (2)
- Release, Apply a Blur value +8%

The generated blur quickly becomes too much. We have to stay on low values.
Click and hold the blur adjustment slider and move it to the right for more precision (Windows only).

The man's face is in the shadow.
> Control Point, Exposure +0.5IL

- Right Click: Choose Control Point (B)
- Left Click on the man's face

- Drag to adjust the diameter tool application (3)
- Release, Apply Exposure value at +0.5 LI

- Close the "Local Adjustments" tool with the button on the top bar
   or the "ENTER" key

Now the picture is well-balanced.
