Quiting school by next, there was one last thing I wanted to share with you from there.
Using a binocular magnifying glass, sort of a microscope, I took a picture thrue the objective, of a 7" vinyl.
The binocular has a smaller magnification power than a micrscope but you can have a wonderful look to the surface of differents materials. I don't know exactly the magnification on the pictures but just take a 7" to look to the spaces between the grooves to give you an idea.
It's the B-side of a repress, nothing very crucial (I can't remember it by now), so not very historical grooves
Still, for me it's just magic how the music we all love can come out of such tiny plastic curves...
Its amazing what you sometimes find in ja vynil,bits of paper, a crushed herb seed,the vynil we use today came out first in 1950 with the new plastic.
peace
Those records look like they need a session on my Moth RCM!
But hey, thanks for posting them they are so cool. I've looked at vinyl using a hand held micoscope but never figured out how I could take a picture. Sometimes when you have a jump you can actually see the defect that is causing it via the scope. Usually it is dirt that can be removed, but sometimes you can see the grooves are actually defect, with one running across another on some poor pressings.
Les, Nice nice job with those pictures - but when are you gonna fess up and tell us the joke is on us, those are actually close-up pictures of your bicycle tires
