I keep trying to work out if rust scales or not, and whether one can tell how big the original is by looking at the crystal sizes. I think possibly not without information on how long it's been rusting or something like that.
My first answer would've been 'no, it's fractal' but the structure of rust is actually based on the granularity of the steel. A complicating factor is that we're looking at a drawn wire, with a tendency to form a coaxially-layered network of cracks which will be expressed as the pattern of rust flakes when corrosion sets in.
The background is dark because round trip distance between flash and sensor is a factor of ten or more bigger for the background than the subject, giving a factor of 100 more light from the subject than the background; and the ambient light is negligible compared to the flash.

And maybe up the contrast, just to see how it looks.

Is the black background from postprocessing or did you have a black backdrop or similar?
