Long day, so I grabbed a piece of coral (2 inches) from the desk that I picked up on the beach last summer. The details that come through when you shoot with the macro extension tubes are finer than they appear to the eye. Seeing how the pictures turn out always reminds me how creative our God is.
Nikon D50: ISO 200 , f 5.6 , 1/60 sec with Quantaray 18-50mm lens and Kenko 36mm Extension Tube
