macro photography of the surface structure of some material? macro shots of something under a microscope?

:beer: for you
material under a microscope is a little too general (i was hoping for "metal under microscope), but you're the closest
the first picture is as-received brass, etched and put under an optical microscope
the second picture is the same brass after a 40% reduction in thickness by rolling, and subsequent recrystallization after about 12 minutes at 400C
