I took some shots of my Martin OX, and for one of them, the pop-up flash was closed. Looking at it in detail, I saw these strange lines - like stray hairs. You have to click on Download to see them. They're not hairs, of course. Funny result.
I have no real idea what has caused them but I see that they seem to originate at the screw heads of the four tensioners. Obviously you were not moving the instrument around. Appears to be some type of reflections. Either that or Aliens are messing with you!
