Overview

Introducing DxO PhotoLab 7

We have tested your camera and lenses

Of course, we should start by introducing our company. DxO is a high-technology firm that specializes in digital image processing. Our engineers have published papers in some of the world’s most respected journals. This scientific, or more accurately — mathematical, background has enabled us to develop DxO PhotoLab as a tool aimed at not just at improving image quality, but at achieving perfection, or rather automatic perfection to be precise.

What makes DxO PhotoLab so special is that we test all of the equipment that you use in our laboratories. Each camera and lens spends several days in the hands of our technicians, who measure not only optical defects such as distortion, vignetting, and lens softness, but also the noise, colorimetry, and tone curves for each piece of equipment. They even analyze any in-camera processing that is applied to images.

The results are gathered together in a unique world-first database. It is this database that gives DxO PhotoLab the information it needs about the camera and lens used to shoot a given image, along with the aperture, focal length, exposure time, etc., to be able to calculate all necessary corrections — that this pixel needs to be brightened by x%; that that pixel needs to be moved by a particular distance in a particular direction; that yet another pixel needs its red channel adjusted, and so on. But all of these corrections require no effort on your part: the software downloads the profiles of your camera and lens all by itself, and then applies the necessary changes automatically.

Our software analyzes each of your images individually

Each photograph is unique — even photographs of the same subject under similar shooting conditions will differ from one another. One may contain a slightly overexposed area. The other might be too grainy because of noise in a dark shadow. A third photo might lack a bit of contrast. How do you deal with such variance?

For most photo software developers, the answer is simple: they will provide you with a number of correction tools and then leave you to fix each of your photos one at a time. That is not our approach. We think DxO PhotoLab, and not you, should analyze each image to determine whether corrections are necessary and apply them. This leaves you to judge the resulting output and then adjust any of the applied corrections according to your own tastes if you wish.

What DxO PhotoLab does to your images

• If your original photo is in RAW format, DxO PhotoLab deals with it using the latest and best RAW converter. During the “demosaicing” process (which converts raw data from the sensor into red, green, and blue pixels), this converter produces an image that is free of artifacts.
• Without any user intervention required, DxO PhotoLab corrects four optical defects: distortion, vignetting, lateral and longitudinal chromatic aberrations, and lens softness. It does this thanks to a unique database containing years of information on the optical defects of photographic equipment (lenses and cameras) tested in our laboratories.
• DxO PhotoLab subtly retains highlights, while preventing clipping, and even recovers certain details from areas that have already been clipped. We advise you to work in RAW to take advantage of the greater latitude in processing.
• Thanks to our laboratory measurements, DxO PhotoLab includes unrivaled denoising tools.
• DxO PhotoLab offers an exclusive correction to selectively improve contrast and brightness in the shadows. This correction’s effect is similar to fill-in flash, radically transforming underexposed, backlit, or extremely high contrast images.
• DxO PhotoLab a unique tool for modifying the color rendering of an image to make it look as though you took the shot with a different camera, or were using negative film.
• Essentially, the software automatically performs nearly all of the corrections mentioned above, leaving you to just fine-tune or adapt the results to your taste.

The functions that are only available in the ELITE edition of DxO PhotoLab are highlighted throughout this guide.

For easy reference, special features for computers on Microsoft Windows are indicated by “PC “, while those running macOS are marked with “Mac ”.

About DxO FilmPack plugin for DxO PhotoLab

DxO FilmPack brings all the quality and emotion of Fine Art photography to digital photos by associating the precise look of silver-emulsion film with quality rendering and creative effects. Based on DxO Labs’ advanced calibration technologies, DxO FilmPack faithfully restores the characteristic colors, contrast, saturation, and grain of dozens of legendary films.

DxO FilmPack for PC and Mac comes in two editions, ESSENTIAL and ELITE, which differ in terms of the number of film renderings and features available. DxO PhotoLab contains a trial version of DxO FilmPack, which can be launched via the Help menu (PC) or the DxO PhotoLab menu (Mac). The free trial lasts for 31 days.

As a plug-in for DxO PhotoLab, DxO FilmPack is completely integrated into the DxO workflow and appears as a dedicated palette in the Customize tab. This version gives you the best performing and most comfortable of user experiences. Indeed, it lets you deal with a whole batch of images in one go as part of a totally reversible RAW workflow.

About DxO ViewPoint plug-in for DxO PhotoLab

DxO ViewPoint fixes even the most complex perspective problems, and easily restores the natural shapes of subjects situated on the edges of images. It also lets you locally correct image geometry and apply a miniature effect.

As a plugin, DxO ViewPoint integrates perfectly with DxO PhotoLab: all features are easily accessible in a new dedicated palette. DxO ViewPoint can also be used as a standalone application or as a plugin for Adobe Photoshop, Photoshop Elements, and Adobe Lightroom Classic.

Once installed, DxO FilmPack and DxO ViewPoint can be activated using their respective activation codes, directly from within DxO PhotoLab via the File menu (Mac) or the Help menu (PC).

Getting started with DxO PhotoLab

After installation, when you are using DxO PhotoLab for the first time, or following an update, the program will run a number of functions to help keep you informed:

• Choosing the default correction preset
• The default workspaces

Choosing the default correction preset

The first time you install and launch DxO PhotoLab, whether it is the first time following your purchase of the software or its installation on a new computer, a dialog and information window will ask you to choose a default correction preset which will determine the behavior of the program accordingly. These presets are:

1. DxO Style – Natural: Choice #1 lets you apply automatic corrections upon opening images in the program. These corrections include the default DxO Style – Natural preset, which corrects tonality and noise, and the DxO Optics Module which takes care of the corrections of lens defects in the camera/lens pair. This is the normal operation of DxO PhotoLab and is intended for those who use it as their primary image processing software.
2. DxO Optical Corrections: Choice #2 is intended for photographers who just want to entrust the automatic correction of camera/lens defects to DxO PhotoLab, while leaving them to manually set all other corrections, either in DxO PhotoLab itself or in another program. .
3. No correction: Choice #3 lets experienced photographers take control all of their corrections, so no automatic adjustments will be applied to images when they are opened in DxO PhotoLab.

To make your selection:

1. Click on one of the three options.
2. Click on Set as Default.

If you want to change the default behavior, simply select the desired correction setting in the Preferences:

• PC: Go to Edit > Preferences > General, and then in the Correction Settings section, choose the desired preset for RAW and RGB files (JPEG, TIFF).
• Mac: Go to DxO PhotoLab menu > Preferences > General, and, in the Default Preset section, choose the desired preset for RAW and RGB files (JPEG, TIFF).

The default workspaces

DxO PhotoLab offers 2 default workspaces, which you can select from the Workspace menu:

• DxO Standard: For beginners or minimalist users, this workspace displays the Basic Tools palette in the Customize tab, which groups together the most common tools you will use during image correction.
• DxO Advanced: For advanced users, displays all correction tools in the Customize tab.

Of course, if you use a custom workspace, you can return to it at any time by selecting it from the Workspace menu.
