The procedure for applying a normalization correction is practically identical between images in two open documents (e.g., a Catalog and a Session or two Catalogs) as it is in the same document. Note that Capture One automatically converts the color values between spaces if the two documents have different output profiles selected. Moreover, the option to open more than document at a time must be enabled in the Application Preferences (Capture One/Edit (macOS/Windows) -> Preferences -> General tab -> Catalog and Session -> Open in new window).
- Select the image in the Browser.
- Open the Output tool tab and verify the color space in the ICC Profile field of the chosen Process Recipe.
- Open the Color tool tab and go to the Normalize tool.
- Enable the White Balance and/or Exposure options with a check-mark.
- Click on the Pick Normalize Color eyedropper or use the keyboard shortcut N in one document and select the reference area (e.g., a color patch, skin-tone or gray card, etc) in the image in the Viewer.
- The Pick field is updated with the selected color and the corresponding RGB values are listed alongside for the selected ICC Color Space Profile.
- Click on the Apply Normalization eyedropper or toggle between the pickers using the shortcut Alt+N. This eyedropper will now be enabled in your second open document.
- From the second open document, click on the area in the destination image (i.e., that you want to apply the normalization correction to) with that document’s Apply Normalization eyedropper. The correction is applied and the destination image is updated in the Viewer.
NOTE: The Normalize tool is not present in Capture One Express.
