DxO PureRAW can be used as a standalone program to process your RAW files. At the end of the process, you will have the choice to send the processed files to another editing program. You can also do batch processing by sending the files to a queue. Export to another program and queuing are described in the relevant pages of this user guide.

The first steps in the workflow when using DxO PureRAW in standalone mode is to do the following:

  1. Adding photos.
  2. Installing and managing DxO Optics Modules.
  3. Selecting the photos.
  4. Starting photos processing.
  5. Verifying and comparing photos.

Adding photos

DxO PureRAW does not allow you to import images directly from a camera or memory card. To do so, you’ll need to transfer the images to your hard drive using your choice of software or device. Once they’ve been added to your hard drive, DxO PureRAW allows you to add photos either by navigating to the folder where they’re saved, or by dragging and dropping them onto the program’s screen from a Finder (Mac) or File Explorer (PC) window.

The first time you use DxO PureRAW, the view that allows you to add photos is empty and instead suggests the following buttons and explanations:

Add RAW files with the Widget

You can ask DxO PureRAW to launch automatically when you insert a memory card or connect an external drive to your computer. To do this, you must activate this option in the Preferences:

Note that if the option in the preferences mentions SD memory cards, it naturally applies to any type of memory card.

To add RAW files with the Widget:

Add RAW files to the Lightbox

Drag and drop RAW files

Download sample RAW images

If you are using DxO PureRAW for the first time and/or have no images:

Installing and managing DxO Optics Modules

DxO Optics Modules

When you add images to DxO PureRAW for the first time, or new images taken with a new camera, the program will automatically ask you to download and install the DxO Optics Modules that match the equipment used to take the images. This information is included in the EXIF metadata of the images.

DxO Optics Modules improve lens performance and correct the following lens flaws:

Downloading and installing DxO Optics Modules

Once images have been added, if no DxO optical module has been installed or if the modules are missing, a window will automatically open and offer to download and install the DxO optical module(s) that correspond to your equipment, the camera body and lens.

To do so, you will need to be connected to the Internet. This screen is made up of the following sections:

  1. DxO Optics Module detected and ready to download.*
  2. None of the above (correction will not be applied): if the DxO optics module offered does not match the equipment, you can check this option to prevent any optical corrections being made.
  3. Save: Start downloading the DxO optics module(s). If you do not use them immediately, they will be suggested again the next time you add photos taken with the same camera-lens combination. The modules are installed immediately so you do not need to restart the program.
  4. Cancel: Closes the window without downloading or installing any modules.

*In the event of any ambiguity, for example if the EXIF metadata do not allow the program to determine which lens was used because there are multiple versions or generations available, the window will suggest several possible choices so you can select the correct DxO Optics Module manually.

You can use the DxO Optics Modules in one of three ways:

If you try to process an image without downloading or installing a DxO Optics Module for the equipment used, the processing options window will show an alert. When you click on the yellow alert the dialog box for downloading optics modules will appear to enable you to install the missing module(s).

If you want to display the list of installed optics modules and those awaiting download, go to the DxO Optics Modules menu and select the DxO Optics Modules option.

The same window that appears during the downloading stage will open showing the status of the DxO Optics Modules:

  1. Downloaded: The DxO Optics Module is downloaded and installed.
  2. Download available: The DxO Optics Module can now be downloaded.
  3. In use: Indicates the DxO Optics Module currently in use.

Selecting the photos

Select the photos in the Lightbox

Selecting your images means picking the photos you want to process. You can select a single photo, multiple photos, or all photos in a folder.

Selected images have lighter grey frame and a cyan border around the thumbnail. To select photos:

To instantly select all images displayed by DxO PureRAW click on Select all, on the right of the upper toolbar. When images are selected, the option becomes Unselect all. By clicking on it, you will deselect all selected images.

If you want to deselect specific images, click on the thumbnails with the cyan border and checkmark. However, it is faster to click the Deselect button.

Clear the Lightbox

The Clear Lightbox option in the upper toolbar lets you purge all images from DxO PureRAW. This feature is useful if you regularly edit large quantities of photos and want to start afresh with a blank screen when you’re ready to process a new batch. Note that:

Starting photos processing.

After having chosen and selected the photos, you are ready to process them. This involves applying optical corrections, using the DxO Optics Modules, and then partial demosaicing with noise processing to generate either: a linear DNG file (which retains RAW file latitude) to finish processing in your preferred program, a TIFF file (which you can also correct and retouch with your usual photo software), or a JPEG file for immediate use to send or share.

To find a description of all processing options and settings, please check the Processing tools and setting page.

To start processing, you can click either on:

Please note:

Canceling or interrupting optimization

  1. A Pause button lets you momentarily interrupt image processing. To resume, click the Play button.
  2. If you click Cancel all batches, a dialog box will ask you to confirm your request.

Verifying and comparing photos

After processing your photos, and before proceeding with further corrections with your preferred editing software, DxO PureRAW lets you quickly check the results and compare them with the original files.

Filtering photos

The Lightbox displays all of the images, whether processed or not. You can filter them using the sort and filter buttons in the top right-hand corner:

  1. Image sorting (left button): You can sort images using one of the following criteria:
    • ISO : arranges photos by ISO range, represented by collapsable sections in the Lightbox. The ranges are <400, 400-1600 and >1600.
    • Date: arranges photos by date-taken in collapsable sections in the lightbox. You can reverse the display order by clicking on the arrow to the left of Date; by default, the most recent image appears at the top of the screen.
    • Name: displays photos alphabetically. Names that start with a number appear at the top of the screen, there are no collapsable sections.
  2. Image Filtering (right button): You can filter images using any of the following criteria, and combine them by checking them in the list:
    • Unprocessed: displays only unprocessed images.
    • Awaiting processing: displays only queued images that have not yet been processed.
    • Processed: displays only processed images.

Note that you can combine image sorting and filtering (e.g. by date + not optimized).

Display, check, and compare photos

Once the photos are processed, you can check them in the Viewer in two ways:

Thanks to the split screen Viewer, you can easily compare the processed image with its original. Inspect the effect of the corrections made by the DxO Optics Module, and judge the improvements in sharpness and denoising. You can zoom into the image at 1:1 (that is, 100%) or you can use the mouse wheel to magnify the image up to 1600% to see the finest details.

You can use the left and right arrows on your keyboard to scroll through the images in the filmstrip. The checkboxes in the square thumbnails of the filmstrip let you select the images, even when you return to the Add photo screen (by clicking on the X button at the top right of the image), thus allowing you to immediately start exporting the selected images to your image editing program (see Working with processed images).

For more information about display and comparison modes, see the User Interface page.
