Thanks all for the responses to my question. I will try the suggestions,
specially the one about the date command. I am still somewhat concerned
about the introduction of extraneous characters. I would like to know if
indeed sed (at least the version I am using) is responsible for the extra
characters.

} The resulting file name may contain an extraneous character (does not

added a } character. The processing continues because the loop is
selecting all jpg or } nef files, but trying to do something with the file
from the command line } results in file not found. I can see the extra
character in konqueror.
Various people have suggested how to rename things already, but I'll point
out that you aren't using date to its fullest to begin with:
newdir=`date +%Y%m%d_`
No need for sed in that one.
