Do you like to see what the hard drive looks like from the inside? I was fixing this computer from work and I came across this computer with an unreadable hard drive, before I threw it out I tried to open it up and thought of just making a coaster out of it. I also took a few snaps of it and post the picture of it to share with you. The hard drive is basically a metal disc where a bunch of 1’s and 0’s are read and written into by a precision mechanical arm that goes across the disc while it spins. Well my exposure on the background is F/5.6 and the picture inside the frame is F/4 both at 1/250 second at ISO 200. I used a single LumoPro LP160 at 1/16th of the power, I think.
