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, 94; all options are available).
To create a
NEF (RAW) copy, choose an image quality of NEF (RAW) and an
image size of Large (the overlay will be saved as a large NEF/RAW
image even if Small is selected).
1 Select Image overlay.
Highlight Image overlay in the
retouch menu and press 2.
The
dialog shown at right will be
displayed, with Image 1
highlighted; press J to display
a picture selection dialog listing only large NEF (RAW) images
created with this camera (small NEF/RAW images can not be
selected).
