LED
I think LED must stand for Little Electronic Device. This LED die has now become the tiniest thing I’ve photographed for a client. For scale, that is a dime shown next to it. The die is so small it was hard to tell which side I was supposed to photograph. Only after I took the picture could I tell if it was the right side and getting it turned over was just as difficult. It took a few trial and error shots before I finally got it right side up.
