If you have taken the photo yourself, then you are usually the owner of the copyright. However, in UK law, if you take a photo of a copyrighted artwork, then the copyright belongs to the artist, unless the artwork is on public (FREE) display.
A photographer's copyright usually expires 70 years after his/her death. It is then free. If there is no identifiable photographer, copyright expires 70 years after the photo was taken.
BE CAREFUL IF TAKING PHOTOS IN GALLERIES AND MUSEUMS. The gallery or museum is able to apply special contractual conditions that restrict your rights to do this.
