300 N The Retouch Menu: Creating Retouched Copies
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 overlays created 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, 92; all options are available). To create an NEF
(RAW) copy, choose an image quality of NEF (RAW).
