Set-up for transmitted light photography

Various examination techniques were used on the cartoons to gain as much information as possible about their condition and their original construction. We think the cartoons were cut up into strips as part of the weaving process in the 16th century and these strips were reassembled onto canvas at the end of the 17th century. This canvas backing makes it difficult to see just how Raphael and his assistants would have made the cartoons. Transmitted light photography allowed us to 'see through' the cartoons.
