New book...A DEEPER, DARKER TRUTH

[Albert Rossi]

Some time ago Jack White and i defended Tom Wilson's work on another forum. His life long work and expertise was in detecting flaws in metal ingots at a U.S. Steel's foundry. He used photographic methods in this work, and then later appied the method to analyze photographs. There is nothing mysterious about it, as it is based on scientific principles involving light and its interactions.

Hi Adele,

Is this discussion still available somewhere? I would like to read it because offhand I would think that there is a difference between using light reflected off a metal surface to determine something about the composition of that surface, and using light reflected off a 2D photographic representation of an object to determine something about the composition of the represented object (not the composition of the photograph itself). I am (earnestly) seeking enlightenment (if you pardon the pun) here ...

Thanks!
