Image overlay combines two existing NEF (RAW) photographs to
create a single picture that is saved separately from the originals;
the results, which make use of RAW data from the camera image
sensor, are noticeably better than photographs combined in an
imaging application. The new picture is saved at current image
quality and size settings; before creating an overlay, set image
quality and size (
0 90, 93; all options are available). To create a
NEF (RAW) copy, choose an image quality of NEF (RAW).
