Walt Snyder, AgX forever, not only but in there

a psychedelic color negative film

cyan magenta yellow dyes (red green blue emission)
pick emission nearest tristimulus values
print paper red green blue dyes, nearest opposite of tristimulus values

correct for spectral mismatch with tristimulus and opposite of tristimulus

modulation to get correct wavelengths

mis match?

frequency modulation of wavelengths

chemical wavelength frequency modulator, apply DC, electric field
application

scanning target (color negative)
ideally scanner should recieve emission as tristimulus values
if perfect as such, need no characterization target
match scanner to film
recieve scanner emission, invert,apply correct DC, amplitude modulate
frequency

target recieves scanner emission, inverts emission, amplitudinally
modulates frequency

the film (as above), chemical inverter upon reception, modulation as
referred to above, upon inversion

5 layer film
chemical inverter - spectrally opposite of first layer
chemical freqamp
freq - perfect black and white layer (grid)
amp - green grid layer
