X-Rays Reveal Hidden Portrait Under Painting By Edgar Degas

An anonymous reader quotes a report from NPR: Using specialized X-ray imaging, a team of researchers in Australia has revealed a striking painting of a woman's face hidden under French Impressionist Edgar Degas' Portrait of a Woman. The researchers believe the auburn-haired woman in the hidden work -- which they also attribute to Degas -- is Emma Dobigny, who was reportedly one of Degas' favorite subjects and modeled for him in 1869 and 1870. "Degas painted directly on the underlying portrait with no intermediate ground paint layer using exceptionally thin paint layers, thus little pigment is present to provide hiding power," the researchers explained in the journal Nature. "The hiding power of paint layers often decreases as oil paintings age." Even as the traces of a ghostly form emerged over the course of decades, conventional imaging technology could only provide hints of what the hidden portrait looked like. Now, an enhanced process known as X-ray fluorescence elemental mapping gives a far better picture. The technique allowed the researchers to scan for the individual elements -- such as iron, zinc and copper -- found in different colors of paint. The team said the maps "can be used to deduce pigment use based on the elements observed within the context of the painting." For example, "Fe and Mn are co-located in the hidden sitter's hair [...] strongly suggesting the use of the brown pigment umber." The researchers detected cobalt in the face, and deduced that it is "probably present as a blue pigment, which is useful in defining flesh tones." This chart shows maps of elements the researchers tested in an effort to create a representation of the hidden work.

I like the original, hidden portrait better. Seems warmer and more alive. The newer painting almost looks like a woman in mourning.

The first is in morning, which was a mistake The second in mourning,.


Those are some big vulcan ears on the first one.

It was never actually finished. It's very good but with rough brush strokes and it's been reworked as he changed his mind.

I also wonder if the method used to figure out the colors used may have cause them to come out much brighter than they were originally. It does seem brighter than many Degas pieces. Another reason for painting on the top being darker may be due to the use of varnish over the surface which can darken as it ages.

invalidate Photoshop patents, this is prior art

first known use of layers with transparency to enhance art ;)

Not a bad effort seeing we have only had electricity here for 30 years.

Canvas reuse

It is not the first time we discover a hidden painting below a master's piece. Nowadays famous artists were poor when they painted, and canvas reuse was a common practice to save money.
