I was trying out my D800E, shooting a few bees on the rosemary bushes out back using my old AF 105D macro and a flash. The resolution of the camera is surprising, as expected. But I didn't expect the occasional rainbow colors on the wings of the bees.
I'll attach a center-section crop that shows what I'm talking about, reduced to 300KB. Hopefully still visible. My question is... moire, or just a natural prismatic effect? All thoughts welcome! Photo was taken at f/22, 1/250.
