Macro without a macro

My macro lens is off at Sigma getting refettled to work on the D7000 so my macro capabilities are limited to the Nikon 50mm f1.8 and a set of extension rings. With all 3 rings in place is really is a very close quarter macro, probably better than 1:1 magnification but very hard to use. This was was the number 2 ring removed and the 3+1 rings in place, light was from the Nikon SB-800 with a diffuser fitted. Subject? A dandelion!
