This was one of my first attempt shots for our macro-photography course. I used the pb-6 bellows, two extension tubes, and the 105 mm micro lens. In all, there was 280.5 mm of extension. I set up the butterfly with a blue piece of foam board behind, which had white spots on it. I was attempting to have the sky look as if it had clouds in it.Nikon D200 - ISO:100 - F/22 @1/250th
