This, or something like, must be the explanation. The silver iodide-bromide layer is far too thin for an interference effect. It might also be a plasmon-polaritron effect which one might argue is the same thing. --- Original Message --- On Sunday, November 27th, 2022 at 9:08 PM, Robin

I don't remember reading anything about that. But in my personal experience, the plate reverts to a murky gray, with slightly darkened outlines of the colored areas. The original color of the over-exposed plate is sort of purplish black. MSf --- Original Message --- On Sunday, November

Hi, Silver atoms may arrange themselves in clusters of a size matching the wavelength of the light. Then the clusters are selective for (resonate at) that wavelength. >On Sun., Nov. 27, 2022, 2:58 p.m. MSF, wrote: > >> >> This effect was studied extensively thoughout the 19th and early 20th >>

Wow... When you say the colours faded do you mean the plate reverted to being completely black again (i.e. its over exposed state)? Harry On Sun., Nov. 27, 2022, 2:58 p.m. MSF, wrote: > > This effect was studied extensively thoughout the 19th and early 20th > centuries, but in another field. Ea

This effect was studied extensively thoughout the 19th and early 20th centuries, but in another field. Early researchers in photography noted the same effect and more in their experiments with Daguerrotype plates. A purposely over-exposed plate would turn very dark. If the plate was covered with

This question is as old as computers and a college class mate wrote about this around 1975... The falsification is trivial as all mappings from reality to software are surjective that is a real= "nature state" is mapped to a  range of real number values. (So the reverse fails to be unique) So
