^[1]Between 1999 and 2003, Article 32 of the 1992 law stated that the term of protection for photographs was to be calculated starting from the 1st of January of the year of their actual completion (and not starting from the next calendar year as is the case in many countries). The term of protection for a photograph completed on December 31, 1974 was thus calculated starting from January 1, 1974, and expired on January 1, 1999.
