LP grooves

[pwnell]

I am sure this has been photographed a lot on here, but here is my take on a (rather boring) perpendicular view of the grooves that gets translated into sound via a stylus (all images stacked using Helicon Focus mode B):


4x, External illumination


10x * 2, External illumination


20x, epi illumination (X-Cite MH) - Quality is not that good due to stacking artifacts and reflection.
