Did this for the Wire challenge, but then in post-processing I went a bit wide of the Standard editing rules, so couldn't use this particular exposure for that challenge.
I intended to created an abstract. I started out by creating a small wire sculpture out of several feet of 26 gauge silver wire and then attaching it to a stand in front of my macro lens, camera on a tripod and on Bulb for long exposure. I used fairly harsh lighting because I wanted the glinting off the wire to be a part of the image.
I sighted five points of focus within the frame, marking down where on the lens' focus window each point fell for my reference during exposure. Then I put an ND 3.0 filter on the lens to help get as long an exposure as I needed, which turned out to be 50 seconds. I started the exposure at the first point of focus, and then at 10 second intervals moved the focus to the next point, and so on, until I had exposed all five points of focus.
This long exposure+multiple focusing technique tends to leave you with a slight "glow" effect overall, with several points of focus at various depths breaking through all around the image. Some examples in my portfolio that use the technique:
In post processing, I eventually produced two versions of this same exposure that I liked, and also took one of these versions and flipped it horizontally and then vertically. I then took all three processed versions and blended them together with the "harsh light" option.
why "Pluto's moons"? - just because I happened to read about the "chaotic" orbits of Pluto's moons recently and it made me think of the chaotic lines in this abstract. In actual fact, their orbits are not at all similar to what you may see in my image, but I liked it as a title, so I ran with it. Here's what Pluto's moons in orbit actually look like:
