ORIGINAL:
Had some down time and thought to try and see if prismatic effects can be incorporated into an image in an artful way, without turning it too cheesy.
(Was going for a different, higher-mesh, dragon, but the Rhino Sub-D is not following the spike details very well at this moment, so this lower mesh dragon will do for now).
Forgot to mention this originally (it’s been two years), this is not a texture in the background. It’s the dispersion of the two prismatic optical devices on each side. They contain a prism and a magnifier glass to amplify the spectrum. So the colors of the dragon are basically dispersion caustics through glass.
