Snowflake macro: ice rainbow

This crystal was captured 21 march 2013. I decided to process some more snowflakes from last winter's archive. In center of this crystal can be seen coloured areas, caused by thin film optical interference effect (thanks to Don Komarechka!). Nice description of this effect in Wikipedia.


Sometimes i saw similar colors in other crystals, but often these colors too subtle. I amplify it by averaging 16 serial shots (this removes most of color noise and makes coloured areas better defined), and enchance colors in LAB space (applied identical S-curves at channels A and B).
