In search of bokeh...

Got one smilar to this yesterday at the botanics in Edinburgh, so went back that way again today to have another go. Still think yesterdays was slightly better but liked this as today's blip. Taken with the Nikon D90 and a Nikon f1.8 50mm prime lens. I think I took this at near on f1.8 trying to get the crazy bokeh effect. Vignette added on photoshop.
