Forgive me, please, if I speak out of ignorance, but doesn't a change in 
wavelength translate into a shift in color (shorter wavelengths being 
bluish and longer ones being redish).  It is with some degree of 
trepidation that I, a newcomer, contradict Dr. T, but I believe that the 
scattering of light is just that; spreading it around, as opposed to 
changing its frequency...and that a small scattering might appear as a 
loss of contrast and a more severe scattering as a loss of sharpness.  
Please tell me if I am wrong.
