CLEAN : Art detectives probe what lies beneath a Fragonard

The video tutorial discusses advanced imaging techniques, including X-ray and hyperspectral IR cameras, used to analyze artworks. It highlights the discovery of hidden layers in Fragonard's painting, 'Young Girl Reading,' revealing a previous composition. The tutorial also covers conservation methods to uncover underdrawings and earlier paintings by minimizing light scattering and absorption by pigment particles.

What is one of the main challenges in filming X-rays for art analysis?

• The requirement for special lighting

• The high cost of equipment

• The difficulty in capturing clear images

• The need for a large team

What was discovered beneath Fragonard's 'Young Girl Reading'?

• An outline of a previous painting

• A layer of gold leaf

• A hidden signature

• A sketch of a landscape

In what year was a previously unknown drawing by Fragonard discovered?

• 2012

• 2018

• 2015

• 2010

What technique is used to reveal underdrawings in paintings?

• Laser ablation

• Infrared reflectography

• Ultraviolet light scanning

• X-ray fluorescence

Why is it important to minimize scattering from pigment particles in art conservation?

• To enhance the color vibrancy

• To better analyze underlying layers

• To reduce the risk of damage

• To speed up the conservation process
