Interaction between ExifTool and PSCS2 for NEF derived images.

Thanks for the sample image, and for helping with
testing.<br /><br />

I have released <a href="http://owl.
phy.queensu.ca/~phil/exiftool/">ExifTool
6.26</a> which fixes this problem.<br /><br
/>

The problem was that ExifTool created a SubIFD in the JPEG
image when copying all tags from an NEF image using
"-all:all".  This does not happen unless
"-all:all" is used because then ExifTool is free
to write the information to its preferred location rather
than the same location as in the original.  Technically a
SubIFD shouldn't be exist in the JPEG EXIF information, and
apparently PSCS2 doesn't know how to handle this properly
because the SubIFD information is corrupted after editing
with PSCS2.<br /><br />

The solution was to prevent ExifTool from adding a new
SubIFD to an image.  The SubIFD is used to store
alternate-resolution images in TIFF and some RAW images, but
is not normally used in JPEG images.<br /><br />

I suggest upgrading to ExifTool 6.26 or later if you are
copying information from any image containing a SubIFD to a
JPEG image with "-all:all".  SubIFD information
may exist in TIFF images and the following RAW formats: NEF,
PEF, DNG, RAF, ERF and SR2.  (Note that CR2, ORF or SRF
images do not contain a SubIFD even though they are
TIFF-based.)
