Well, my wife officially thinks I'm crazy. I got home a little early from work today, so I went out on the balcony to see if my arachnid model was still around from yesterday. Sure enough, he was sitting right there on the tomato plant pretty much where I left him. I just recently bought a reverse ring for my new 28mm, but I was really eager to try it out reversed. So I grabbed a roll of technical tape and taped it to my extension tubes. The working distance with this setup actually isn't bad, much better than with the lens on the right way
Peek a Boo!
And a crop of his eyes.
Thanks for looking!
