When I first homed in on this crop, I had in mind making it black & white. But, the initial attempts were unsatisfactory, leading me to post just the color version. Subsequently, I discovered a different, more flexible approach.
A detail from the sculpture "Data and Dust, #4" by Don Porcaro. The bronze / orange structures in the background are actually part of a fence behind the sculpture.
This is a detail from the sculpture "Horizon II" by Bruce Beasley. This reminds me of the structure of metallic grains under a microscope, hence the title.
