The halides in elmusion are particles of specific size. That size
contributes to the film's sensitivity and grain. In essence, they are
reduced by the developer so that they are left intact by the hypo (black)
or dissolved (clear).
The dye molecules are suspended in the polycarbonate layer. They are not in
discrete particles, hence do not scatter. Dust and smoke particles in the
air scatter light, making the sun yellow and the sky blue.
Arguing this technology with Jerry is about as wise as disputing
mathematical physics with Stephen Hawking - except that Jerry *can*
communicate when one is not excessively simple.
