The COMPUTED will contain also an entry Copyright Which is either the original copyright string or it is a comma separated list of photo and editor copyright.
참고: The tag UserComment has the same problem as the Copyright tag. It can store two values first the encoding used and second the value itself. If so the IFD section only contains the encoding or a byte array. The COMPUTED section will store both in the entries UserCommentEncoding and UserComment. The entry UserComment is available in both cases so it should be used in preference to the value in IFD0 section.
