Compositing Images

You can combine two images into a single image. You can further combine images by adding another image to the composited image. Since the composited image is saved as a separate image, the original images remain as they are.

  1. Select a background image in the main window.

    • You can also select a background image from the edit window, edit image window, or [Collection] window.

  2. Select the [Tools] menu → [Start Compositing Tool].

  3. Select the image to combine.

    • Select the image to combine from the [Foreground Image] list box.

    • The selected image is displayed in the [Foreground Image] thumbnail display.

    • A preview of the combined background image and foreground image is displayed in the composite preview.

    • The following images can be combined.
      When a background image is selected in the main window ([Folder] window) or edit window: image in same folder as background image
      When a background image is selected in the [Collection] window: image in the [Collection] window
      When a background image is selected in the edit image window: image displayed in the thumbnail display area

    • You can combine images of differing sizes.

  4. Select a compositing method.

    • Select a compositing method from the [Composite Method] list box.

    • The compositing method selected in the composite preview is applied.

    • The compositing method can be selected from five types: [Add], [Average], [Weighted], [Lighten], and [Darken]. For details on each compositing method, see "Compositing Methods".

    • If you select [Weighted], you can set the proportion of brightness of the image to be combined. Use the [Weight] slider at the bottom of the [Composite Method] list box or directly enter a value to set the brightness proportionally.

    • By clicking the [100% view] button, the image is displayed at 100% magnification (actual pixel size).

  5. Position the images.

    • By default, the background image and the [Foreground Image] are displayed with their centers aligned.

    • Checkmark the [Compose in RAW Format] checkbox as necessary.

  6. Click the [Save As] button.


    • By clicking the [Save As] button, the [Convert and save] window appears. Specify the required settings, and then click the [Save] button.

    • By clicking the [Continue] button, images are combined to create a new background image, and you can continue by combining another image.

    • To finish, click the [Close] button.


  • This function can be used with all image types supported by DPP. However, images with more than 6666 × 4444 pixels are not supported.

  • The color space of a composited image will be the color space of the background image.

  • Image information is not appended to a composited image.
