A tricky image to make. The good news was that there were quite a few of these beauties; the bad news was that they were growing in the middle of some dense poison ivy. Most of that green stuff in the background is poison ivy.
I don't know what happened to the EXIF data, but the pertinent stuff was f/11, 1/40 sec, 180mm, tripod, remote release, RAW using the Tamron 70-300 telemacro which goes 1/2 life size in the 180 to 300 range. The thing that surprised me when I looked this up just now was the shutter speed. I had convinced myself that this lens was really poor in the 1/60 to 1/8 sec range due to mirror slap - in fact, ran a bunch of tests to prove it. But if you look closely you'll see lots of tiny little hair-like thingy's (that's technical talk) on the petals and leaves (hard to see on this web version, but it's there). Wouldn't have believed that this lens could give an image that sharp at 1/40 of a second.
