Hope you are already for another brain buster, just not quite as difficult as the last one. If you missed out on Macro Mystery #1 check it out for a little background on how I actually took the photo. This time around I used a reversing adapter that let’s me mount a 50mm lens backwards, giving me the magnification I need. I also used a tripod so I could fine tune the focus. So here goes.
Update: The image covers about 1/4 inch square and to keep people guessing longer I’ve made the text of correct answers white. So if you get stuck highlight the comments with blank spaces.
