This image captures strings of dish soap being dropped into a tank of water. The dish soap is more viscous than the water so it remains in its stringy form when it enters the water. The report can be found below.

I very much enjoy the fact that you can see each strand of soap suspended in the liquid. I like the brighter colors of this image, compared to the bulk of dark images in the rest of this category.
I like how distinct and thin the strings of dish soap stay as they collect together and suspend in the water.
I like the depth that is given to the image by the out of focus edges.
It would have been nice to have more of a concentration of soap in the middle focus.
Good choice of color difference.
The image does seem a little bit grainy. It could be an ISO issue (needs more light) or just a lack of clarity in the field of view.
Lucas asked if the background subtracted from the image and I think that the texture adds a bit of depth on top of the focus characteristics. It could be edited out but I think the vertical lines add some movement to the image.
I’m a huge fan of the color contrast. I like how the blue pops on the white background. It adds a little bit of texture.
