Pollen Detail Of White Trillium (trillium Ovatum) version 2

I posted on this a while back, but had not yet finished these images. These are complex to produce because obtaining detail and depth of field at this scale can require 20 to 50 exposures or more. The technique is called focus stacking, and it has revolutionized microphotography in the digital image era.

White Trillium (trillium Ovatum)

This lovely native flower makes a brief appearance during spring in the west. The first trillium that pops up is always breath taking - soon to be followed by a small explosion of little white blooms. 


Many flowers have more than one common name, however this one has more than usual:  pacific trillium, trinity flower, western trillium, western wake robin, wakerobin, western white trillium, white trillium.

The white trillium bears distinctive 3-petaled, white flowers in spring above its dark-green leaves.
