i know this is going to sail right over your head, but i might as well put it out there:
the only difference in this image and the ones i posted (of my own work - let's let the expert discern what my wife happened to capture) is the dark spot at the center. the pollen (let's assume - our expert calls them malicious forgeries, so we both agree they are dust) that i'm taking photographs of are of a particular sort. the reflective properties of matter are largely a prodcut of their geometry. the pollen that i've photographed has a solid, opaque form that reflects light directly back towards the camera lens - so it's center is a solid, bright dot in the middle of a cornea that is exactly like the cornea in this photograph. my explanation of this difference is that these are pictures of a differently shaped kind of particle -one that perhaps by convexity or translucence does not reflect light at 180* back to the camera.
if i find the opportunity to photograph a different sort of dust, i'll share it.
now here's a question for you -- why is this the only photograph you've produced that has the dark spot at the center? your avatar doesn't look like this. in fact, your avatar looks a lot more like what you admit is pollen than it does this particular image.
