Is it called "shot" in English? The type of cloth, often in silk, that shimmers in two distinct colors? In Japanese, it's called "tamamushi", meaning "buprestid", according to an on-line J/E dictionary.
Ben phoned to ask if I had any photo for our Photo blog, and I couldn't find anything interesting to show; I usually try to introduce a place, thing or activity in Nelson, or something universally funny on that blog. Then I saw this where the sand looked swept, so I started it cleaning up. I brightened the medium range, and accentuated the contrast slightly, and then exaggerated the saturation a tiny bit, and suddenly all these colors appeared, reminding me of a "shot" cloth. I'd love to weave something like this some time, but probably in a different color combination.
(That's a shadow of my hand and camera there.)
