In this standard the tag is used to indicate both the photographer and editor copyrights. It is the  copyright  notice  of  the  person  or  organization  claiming  rights  to  the  image.  The  Interoperability  copyright statement  including  date  and  rights  should  be  written  in  this  field;  e.g.,  "Copyright,  John  Smith,  19xx.  All  rights reserved." In this standard the field records both the photographer and editor copyrights, with each recorded in a separate part of the statement. When there is a clear distinction between the photographer and editor copyrights, these are to be written in the order of photographer followed by editor copyright, separated by NULL (in this case, since  the  statement  also  ends  with  a  NULL,  there  are  two  NULL  codes)  (see  example  1).  When  only  the photographer  copyright  is  given,  it  is  terminated  by  one  NULL  code  (see  example  2).  When  only  the  editor copyright is given, the photographer  copyright part consists of one space  followed by a terminating NULL code, then the editor copyright is given (see example 3). When the field is left blank, it is treated as unknown. Ex. 1) When both the photographer copyright and editor copyright are given.   Photographer copyright + NULL[00.H] + editor copyright + NULL[00.H] Ex. 2) When only the photographer copyright is given. Photographer copyright + NULL[00.H] Ex. 3) When only the editor copyright is given. Space[20.H]+ NULL[00.H] + editor copyright + NULL[00.H] Tag = 33432 (8298.H) Type = ASCII Count = Any Default = none
