A Bit OT: Infrared radiation and alterations
Posted By: davidcycleback
Just thought some might find this interesting. I took the below two photographs of an acrylic painting. The left is a normal visible light photo. The right is an infrared photo. As you can see, the infrared image sees through the paint of the posts to the paint behind it. The painter painted the bushes first, then painted the white posts over. This type of imaging would be useful in the detection of some altered forgeries, ala T206 Magies. |

Infrared and x-rays are commonly used on famous paintings to see how the artist worked. What changes were made, etc. In a Rembrandt, they discovered there was a person who was removed from the image. On paintings, infrared and x-rays work the same way, except x-rays sees to a different level of paint. |

Couldn't you just get a pair of those X-Ray glasses that they sell on the back of Comic books. |

Those old x-ray glasses ads are funny because, 1) If they worked, they would be dangerous beyond belief. You don't want x-ray receivers mounted two inches from your brain; and 2) It's impossible, even on the theoretical level, for them to work. For them to work, you'd need a unit that gives of x-rays on the other side of what you re looking at. |
