This is achieved by having Nikon Sb600 at the left side, control through commander mode in the Nikon D90 set to manual if not mistaken 1/32 (in the camera) (or could be 1/64) because the Exif does not have the flash information.
This is a very small plant. I thought it is a flower, but later informed by my mother it was not a flower. The plant is use to treat some sickness (I don’t know what). But it sure looks nice.
