In this section you will discover the user interface of DxO PureRAW 3 in standalone mode. This interface is divided into two screens:

Adding and selecting photos

The Lightbox

The photo addition and selection screen, the Lightbox, is divided into 4 sections (from top to bottom):

The Lightbox, for adding and selecting photos
  1. Menu bar: contains DxO PureRAW 3, DxO Optics Modules, and Help (on Mac), or File, DxO Optics Modules and Help (on PC).
  2. Upper toolbar: lets you add, remove, select, select all, or empty the lightbox of photos, as well as sort and filter your images. In the center, the number selected is shown over the total number displayed (for example, 2 out of 10).
  3. Image thumbnail display area: Shows thumbnails of added images sorted by date of capture. When the area is empty of thumbnails, it displays the options for adding files to process (via a system window, or by dragging and dropping into the window) as well as an option to download sample RAW images.
  4. Lower toolbar: lets you start image processing, add to the queue, and displays the image processing progress bar.


When you add images to process in DxO PureRAW 3, they are displayed in the Lightbox as fixed-size thumbnails and sorted by default into collapsable sections, by capture date (day DD month YYYY format: Thursday 12 January, 2023), the most recent date is always displayed at the top of the screen.

The program displays thumbnails in four ways:

  1. Image not selected: a dark frame containing the name and extension of the file with a thin white border around the image thumbnail.
  2. Selected image: light frame containing the filename with a thick, cyan border around the image thumbnail.
  3. Image awaiting processing: clock icon in the bottom right corner of the thumbnail.
  4. Processed image: cyan tick in checkbox, filename, DxO processing suffix and the processed file extension. When you are hovering over the thumbnail with your pointer, a magnifying glass is displayed in the bottom right which lets you open the processed image in enlarge mode.

You can select thumbnails individually by clicking on the images, and deselect them in the same way. To select a continuous series of images, click on the first and then on the last while holding down the Shift key.

Double-clicking on an image lets you display them in the Viewer, regardless of whether they are processed or not.

When optimizing, a progress bar is displayed in the relevant thumbnail(s), in addition to the progress bar in the bottom bar.

There are four ways to access the Viewer:

Displaying images in the Viewer.

The Viewer lets you check the optimization results and gives you the option to compare with the original. To do this, the Viewer displays the following elements:

  1. Image display area.
  2. Split frame separator, which you can move freely to the left or right.
  3. The left-hand section displays the original RAW file.
  4. The right-hand section displays the latest optimized image.
  5. The banner of images displays square thumbnails extracted from the existing images in the Lightbox (use the mouse wheel to scroll from side to side).
  6. You can show or hide the filmstrip by clicking on the chevron at the bottom of the image that is currently displayed.
  7. The left part of the lower bar displays information related to the selected image (format, name, date and time of capture, size in MB, and shooting parameters: ISO sensitivity, speed, aperture).
  8. The lower bar also shows the number of images selected in the filmstrip out of the total displayed.
  9. Buttons for the different display modes (Zoom to fit, Zoom 1:1, Before/after Split view, and Toggle view).
  10. Button to close and return to the Add and select photos screen.

Display modes

At the bottom right in the lower banner, you will find the buttons for the different display modes:

  1. Zoom to fit: The entire image is displayed.
  2. Zoom 1:1: The image is displayed at 100% (1:1 — that is, one pixel of the image is equal to one pixel on the screen).
  3. Zoom 2:1: By default, the image is shown at 200%, and the associated menu lets you check it at various levels of zoom (from 2:1 to 16:1).
  4. Before/after Split view:* Displays the image with a movable vertical separator. The original image is shown on the left while the optimized image is on the right.
  5. Before/after Toggle view:* Displays an alternating view of the optimized image and the original image. Click and hold the mouse button to see the original image, release to return to the optimized image.

* Split and Toggle comparison views are available only when you have selected an optimized image.

Zoom to fit.

Progressive zoom and navigation

From the Zoom to fit view, you can zoom in and out using the mouse wheel to a maximum of 1600% magnification. The zoom value is temporarily displayed at the top of the image. After zooming, you can move around the image in any direction by clicking and dragging with the mouse.

The zoom works with both original and optimized images, including when you are using the split view or the comparison view.
