of camera and lens, image content, constantly changing weather and lighting
conditions, manual and automatic settings, the photographer’s personal taste,
and so on.
With lm-based photography, unless the photographer developed his or her
own lm and prints, much of the workow was left to professional development
houses. Digital photography has changed this and has moved control over all
aspects of the picture creation process into the hands of the photographer. As
well as actually taking the picture, this involves saving, correcting, creative
interpretation, archiving and much more... DxO Optics Pro offers you a range of
incredibly powerful image enhancement tools that you can integrate easily into
your own workow.
DxO Optics Pro does not work in the same way as other post-production pro-
grams. Rather than presenting you with an uncorrected image and expecting
you to make corrections and adjustments manually, DxO Optics Pro automati-
cally determines the best combination of settings for each image you want to
process.
In fact, DxO Labs has calibrated and measured the defects in over 80 camera
bodies and in more than 2000 camera/lens combinations. The measurements
for each camera/lens combination are stored in a DxO Optics Module, which is
used by DxO Optics Pro to automatically correct the defects for this combination.
There are therefore as many DxO Optics Modules as there are calibrated camera/
lens combinations.
Provided the type of camera body you use to take your pictures has been cali-
brated by DxO Labs, DxO Optics Pro can:
• convert and reduce noise in RAW images (e.g. CR2, NEF, RAF, etc.)
• reduce noise in JPEG images
If, in addition, the DxO Optics Module for your camera/lens combination is availa-
ble, you will have access to all DxO Optics Pro corrections, including automatic
optical corrections. If there is no DxO Optics Module available, you will still have
access to all of the DxO Optics Pro corrections but the optical corrections will be
in manual mode (adjustment by user required).
If the type of camera body used to take your photos has not been calibrated by
DxO Labs, DxO Optics Pro will not be able to read its RAW les but will still be
able to make corrections to its JPEG les, including manual optical corrections.
NOTE: If your workow involves using other software as well,
the DxO Optics Pro software must be used as the rst step in pro-
cessing your images. See chapter 1.3 for further information.
1.2 Basic principles of an image enhancement
session
The way the DxO Optics Pro workow is organized deserves a few words of
explanation. Unlike traditional image editors, DxO Optics Pro works on projects,
not directly on images.
A project is a logical group of images that you want to process. The rst stage
in any project is therefore to add your images to it. As you add your images, a
combination of settings (a preset) that describes all the corrections that need to
be made is automatically associated with each one. Managing a project involves
four main steps, each of which has its own tab:
• Select
• Customize
• Process
• View.
Two steps are essential: adding images to the project (“Select” tab) and then
the automatic processing of all the images in the project (“Process” tab). Note
that processing can also be started by right-clicking on one of the thumbnails in
the “PROJECT” pane (cf. chapter 3).
There is also an intermediate step, in the “Customize” tab, which allows you
both to preview the corrections that will be applied to your images when they
are processed, and to manually adjust certain settings on particular images. The
new settings are saved and will be applied when the image is processed (in the
“Process” tab). They can also be saved as presets and applied subsequently to
other images. If you close the software before you have processed your images,
but after you have saved your project, you will nd the same settings for these
images next time you open your project in DxO Optics Pro. Lastly, a nal step
(“View” tab) allows you to check the corrected images.
When you add an image to DxO Optics Pro, the program reads the information
stored in the image’s EXIF data about the camera and lens you have used. This
information is used to link the image to the appropriate DxO Optics Module
and to automatically determine the optimal optical correction settings for one.
Generally, you can then simply start the image processing without making any
manual adjustments to the settings.
REMEMBER: The image data read by DxO Optics Pro must not
have been changed since they were generated by the camera.
If the distortion, lens softness or vignetting corrections are not
