From Seracini video:

Seracini spent 30 years searching for Leonardo da Vinci’s lost fresco “The Battle of Anghiari,” and in the process discovered that many paintings have layers of history hidden underneath. Should they be part of the viewing experience too?
How could science aid / alter how we deal with authenticity?
How did Seracini incorporate technology and conservation techniques to change how viewers can interact with paintings today and in the future?
