Macro & Tubes

I have been playing around with some tubes and my 50mm lens trying to get some nice macro. It took quite a while to figure out how to get the camera to work with the tubs on... If I knew anything at all it may of been easy.. But starting at scratch.. with knowledge.. it took longer.. I will give you one clue your camera must be set on M.... Manual... This is not a great photos but its been the first one I dare post.. I am hoping for a very nice snow flake this week. Today when I was trying to capture one, it was too warm and they were all smashed up.
