Resin Bow Effects

These primary and secondary refraction effects from droplets of resin onspruce tree cones produce very intense colours, at 20 degrees and 90degrees from the Sun direction. The photos were taken out of focus and twostops under normal exposure to avoid colour saturation. In the secondarybow, there is some evidence of "supernumary" colours beyond the violet endof the spectrum, as evidenced by pink colour of the reflections.
