Physically Accurate Dispersion in Rendering light and color

Edwin Braun: Physically Based Spectral Wavelength Rendering
finalRender treats colors totally different from what you might know of other rendering applications on the market. Colors in finalRender are treated as a combination of individual wavelengths, just like in the real world. An overlay of multiple frequencies of light results in the final colors we all see around us. Lets take a rainbow for example, water drops disperse (or split) the sun light into its individual components and this Dispersion of light presents to us this awe inspiring rainbow of colors – right there in the sky!

I took dew (water droplets) as an example of why such effects, even when they are subtle, are so important in creating photo real images.
