Not strictly a macro, since I don't have a macro lens, but hopefully it's OK as a 'closeup detail'.

Post in GIMP - light saturation pump (or maybe I just manipulated the histogram), light unsharp mask which brings out the fine roots. I apply a black border to a lot of my shots - a habit I got into when scanning slides because the scanning process captured a black border automatically and I found I liked the effect - plus I prefer a black background to white. I'm curious if other people like or hate that effect.
