Katrina Putker's image of a dinner plate and cutlery won her third place in the Eureka Prize for science photography, 2008.
This time the birefringence was created by using the light passing through plastic which was manually stressed to enhance the overall effect. When light passes through certain types of material, it experiences two refractive indices, slow and fast wavelengths which creates the rainbow effect.
Ms Putker called her work, "Birefringence Binge"
I'm not sure how 'manually stressed' works, in my case it would be belting it with a geologist's pick.
