Some more shots taken while I learn more about this caper. Both taken with Canon 400d, Sigma 105mm Macro Lense at f2.8, 1/200, ISO200 and using a Speedlite 270EX flash. I piece of white paper held above the flash to help direct light on subject.
First photo is detail of a banksia, second just a little flower. The white petals are only a couple of mm wide.
