x-rays reveal an image hidden by damage

Daguerreotype image
by x-ray – Globe & Mail

Toronto. I had a call from John Linsky Friday morning as I was making breakfast. John had read an article in the Globe that morning regarding the discovery of images on a daguerreotype thought to be long lost.

The scientists in Saskatchewan used x-rays to excite the mercury atoms (daguerreotypes are developed with mercury fumes as you likely know).

Past PHSC president Dr Mike Robinson of Toronto is a modern day daguerreotypist. If you enter the word daguerreotype in the search bar at the upper right, on our web site, you will see our many posts on the topic.

The strategy would help if daguerreotypes are found in the wrecks of the Franklin expedition and have been damaged by sea water. You can read the Globe article here.
