want to apply to your image.

A visualization palette for precise adjustments.

An upper toolbar that includes tools for viewing and navigation.

Lower toolbar for resetting or applying corrections.

Image size in pixels.

Correcting distorsion

All lenses are more or less affected by distortion, whether barrel (lines bending outward towards the edges of the image) or pincushion (lines bending toward the center of the image) — and sometimes both at once. Thanks to the inclusion of DxO Optics Modules, DxO ViewPoint 2 lets you automatically correct the distortions of your speciﬁc lens.

NOTE

DxO ViewPoint 2 optimally corrects distortion for RAW or JPEG images that come straight out of the camera without having ﬁrst been modiﬁed either by the camera or by third-party software.

Step 1 - Open an image in DxO ViewPoint 2 by clicking on File >

Open, or by clicking on and dragging your image into the application

window.

Step 2 - In the Distortion palette, click on the Automatic button

located on the left.

Step 3 - A dialog box will tell you if the correct DxO Optics Module

for your equipment has been installed, or if not, if one is available for downloading (installing a DxO Optics Module does not require restarting the application).

Step 4 - Click on OK to download the DxO Optics Module if necessary

and to correct the image.

Step 5 - Save your image by clicking on File > Save As.

NOTE

If your equipment isn’t supported by a DxO Optics Module, you can still manually correct your image. For more information, see the complete user guide on our website at http://www.dxo.

com/intl/photography/tutorials.

Correcting volume deformation

Volume deformation occurs frequently when using a wide-angle lens to take photos of objects, people, or groups of people. The subjects situated on the edge of the image are stretched or elongated. In our example below, we can see that the young woman’s arm and head are distorted, so we need to apply an appropriate correction to our image to give her a more natural and proportionate look.

BEFORE AFTER

Step 1 - Open an image in DxO ViewPoint 2 that has the same kind

of ﬂaw as shown in the example above by clicking on File > Open, or by clicking on your image in (or dragging your image into) the application window.

Step 2 - Activate the volume deformation correction by checking the

box in the Volume deformation palette.

Step 3 - Click on the Diagonal button on the right. The correction is

immediately applied and the image is automatically cropped.

Step 4 - Save your image by clicking on File > Save As.

TIP

You m ay cancel your corrections at any time by clicking on the Reset correction button located on the upper right side of the palette.

NOTE

DxO ViewPoint 2 also lets you apply horizontal/vertical corrections to objects that are distorted horizontally or vertically. To do this, click on the Horizontal/Vertical button, then follow the same steps as above. You can also ﬁne-tune your corrections by using the advanced tools in the Volume deformation palette. For more details, read the complete user guide on our website:

http://www.dxo.com/intl/photography/tutorials.

Correcting keystoning and horizons

In architectural photos, photographers often shoot a building while standing at its base or from above. In both cases the subject is distorted, with what should be parallel lines becoming increasingly skewed as they approach the edge of the image. In our example, we are at the foot of the building. This perspective lends an unseemly aspect to our composition, so we will have to straighten the convergent lines.

BEFORE AFTER

Step 1 - Open your image in DxO ViewPoint 2.

Step 2 - In the Perspective palette, click on the Force vertical

parallel button. Two vertical lines, each with two circular anchor points, will be superimposed on your image.

Step 3 - Choose two vertical reference elements in your image.

Place the mouse cursor on one of the anchor points displayed and move it to the top or bottom of your reference element. Move the second anchor point such that it lines up with your vertical element. Do the same with the second superimposed line.

TIP

You may more precisely place your anchor points by using

Visualization palette, and you can adjust the zoom level for

even more precision.

Step 4 - Verify your correction by clicking on the Preview button that

appears in the lower toolbar. DxO ViewPoint 2 will darken the parts of the image that will be suppressed when the image is automatically cropped.

Step 5 - Click on the Apply button. The correction is immediately

applied and the image is automatically cropped.

Step 6 - Save your changes by clicking on File > Save As.

You can also manually adjust the cropping of your image. To do this, click on the Crop tool in the Correction palette. Use the composition grid superimposed on your image to deﬁne the crop. You can preserve the original proportions of your image or modify them by using the Aspect ratio menu. Click on the Close button. The correction is applied and the image is cropped.

NOTE

DxO ViewPoint 2 also lets you correct horizontal or even more complex perspective problems. You can also ﬁne-tune your corrections by using the advanced settings in the Keystoning palette.
