PhotoLab’s Optical Modules only take into account photos recorded in raw format if the shooting characteristics have been analysed by DxO’s laboratory . All the available corrections are grouped under the term “Optical Module“.
* Only raw photos taken with an analysed Digital Camera (DC) can be edited by PhotoLab. DNG format photos from a supported DC after conversion by Adobe DNG Converter or Lightroom only are also supported.
See
the tutorial “Mastery of PhotoLab – Two export modes to DNG”
PhotoLab does not open all low resolution or compressed raw formats.
PhotoLab can only apply its advanced PRIME noise reduction algorithms (Elite edition only) to raw files from a supported DC.
See
the tutorial “Efficiency with PhotoLab – Noise Reduction”
PhotoLab can always open a JPEG image from any source (unknown DC, third party software, scanner, …).
* Lens characteristics is a second benefit of the application of DXO’s optimal corrections. The technical improvement of these known and repeatable photo defects can be done automatically and without any intervention by the user because these defects are known and repeatable.
In the case of optics for which there is no Optical Module, the various tools used to improve the image are still available, but it is up to the user to determine the correct settings.

* When opening a photo for the first time, PhotoLab offers to download the optical module of the combo (DC+lens) if it has not previously been downloaded.
To avoid the display of this invitation to download.

all existing camera/lens combinations

Some combos have two modules, one for raw images offering total optical corrections of the raw sensor image, the other for direct JPEGs providing additional corrections to those of the DC.
This icon indicates that no optical module is available.
See the
tutorial “Mastery of PhotoLab – Software Configuration” for downloading out of modules.
The various corrections resulting from the availability of a combo (DC + Lens) optical module.
(1) Sharpness adjustment, chromatic aberration corrections, vignetting and optical distortion will be applied automatically in addition to those applied by the DC
(2) as well as an RGB file (JPEG or TIFF) of any origin (software, scanner …)
DxO does not allow PhotoLab to process raw photos from unsupported DCs. This is because the company wants to ensure that a user’s photos are developed in the highest quality controlled environment.
The same constraint applies to new cameras. You have to wait until they are supported. The DxO lab can take a long time to create a profile. This is frustrating when the cameras are close to the previous range and look similar to older models.
See the
tutorial in the Appendix: “Editing EXIF” for an unauthorized solution.
To match an image to a module, DxO uses several pieces of Exif/MakerNote information in the following order:
– Lens name (LensName)
– Lens specification (LensID)
– Description (e.g. 18-35mm F3.5-5.6) (LensInfo )
– Shooting information about the focal length and aperture (F-number)
The first two pieces of information are supposed to be unique, but not all manufacturers comply with this requirement. Sometimes they are not available (especially for older generation APNs). When an optical module is misidentified, PhotoLab may suggest one or more other lenses with an ambiguous designation.
DxO reports that lens recognition problems are becoming increasingly common. The optical field is evolving with improved versions and products from independent manufacturers.
PhotoLab is not fully compatible with Adobe’s Super Resolution DNG files.
