Image overlay combines existing photographs to create a single picture that is saved separately from the originals. One NEF (RAW) image can be overlaid on another using additive blending ([Add]), or multiple images can be combined using [Lighten] or [Darken] blending.

  • The overlay has the same photo info (including date of recording, metering, shutter speed, aperture, shooting mode, exposure compensation, focal length, and image orientation) and values for white balance and Picture Control as the photograph selected for [Image 1]. Copyright information, however, is not copied to the new image. The comment is similarly not copied; instead, the comment currently active on the camera, if any, is appended.
