Macao copyright law allows the use of works installed at public locations. According to Decree-Law No. 43/99/M of August 16, 1999, on the Regime of Copyright and Related Rights (as amended by Law No. 5/2012 of April 10, 2012):
It is legal, without the consent of the author ... To make copies by photography, videography, cinematography or other analogous means, of works of art placed in public places.[43/99/M/2012 Article 61(l)]
However, the free use of a protected work must not prevent its normal economic exploitation nor unjustifiably prejudice the legitimate interests of the author.[43/99/M/2012 Article 62(l)]
The reproductions allowed under article 61 should not be confused with the original works by those who use them, and the reproduction or citation cannot be so extensive as to detract from the interest in those works.[43/99/M/2012 Article 62(3)]
