Some fascinating looks at the scenes and times when Russia still had a

I assumed these had to be separation negative shots, and the river scene
with the bands of red/green/blue waves clearly demonstrates that. They took
3 black and white photos through either red/green/blue or
cyan/magenta/yellow filters, and then recombined them in some fashion.
