Ace I'll trade you my camera for your tank! hahaha. It took some getting used to shooting macro stuff but I have the basics at least figured out somewhat. I had never really done any macro shots (my wife and I have a photography business, but I am the apprentice kinda guy). I spent the last year doing pinup model sessions and tattoo artists. So shooting in a tank was really hard to get used to. But thank you very much for the kind words. I wish I could take credit, but it is really the lens... I shoot in manual mode and in RAW format. But I shoot with a fix focal length portrait lens (100mm). It does a nice job with macro stuff. As for apparature settings I shoot wide open and this time I dropped my ISO all the way down to 200 and put the camera on a tripod with a timer. The only post processing that I do is to match the white balance to the 14000 K from my light. No other adjustments are made and I have been pretty happy with the results (gotta say, when I saw that Green Pavona I about had a heart attack, I love that picture... not bragging mind you, i just aimed the camera, but that pavona is amazing).
