Retouching Copies
Most options can be applied to copies created using other retouch
options, although (with the exception of Trim movie) each option can
be applied only once (note that multiple edits may result in loss of

out and unavailable.

Image Quality and Size
Except in the case of copies created with NEF (RAW) processing, Trim,
and Resize, copies are the same size as the original. Copies created
from JPEG images are the same quality as the original, while cropped
and resized copies created from NEF (RAW) and TIFF (RGB) images are
saved in JPEG finem format.
