# script designed to help unload photos from camera/cd/or_whatever
# to folders ordered by date based on EXIF info.
# USAGE:  cd /to/the/folder/where/the/files/are
#         sh photo-save.sh
# DEPENDS on: exiv2
# HINTS: if you have multiple cameras you can:
#       - copy this script accordingly: ex.  cp photo-save.sh photo-save-d50.sh
#       - make sure that UNLOAD parameter is set: ex. /home/user/unload/d50/
#       - now use photo-save-d50.sh instead of photo-save.sh
#       - repeat the same for as many cameras you need to..
#       if you didn't already know, you can chmod +x photo-save.sh and copy it
#       to a "bin" folder (ex /usr/local/bin/)
