Retouching Copies
Copies created with Trim can not be further modified. D-lighting, red-eye
correction, filter effects, and color balance can not be applied to
monochrome copies. Image overlay can be applied multiple times.
Otherwise the options in the retouch menu can each be applied once to
existing copies, although multiple edits may result in loss of detail.
A
Image Quality
Except in the case of copies created with Trim (pg. 356) and Image
overlay, copies created from JPEG images are the same size and quality as
the original, copies created from NEF (RAW) photos are saved as large
fine-quality JPEG images, and copies created from TIFF (RGB) photos are
saved as fine-quality JPEG images of the same size as the original. Size-
priority compression is used when copies are saved in JPEG format.
