I posted this image on my camera club Facebook page, and one of the members (who happens to be a nurse) commented......"It's like the perfect vascular system. Showing a nodule as well (the nest) in the upper right quadrant."
I love her description and have to say that I totally agree!
I chose black and white for this image, and gave it a bit more processing than I normally do, but I am pleased with the way it came out. I hope you like it too.
