This is my attempt to salvage a photo shoot that left me wholly unsatisfied; Not enough light, poor focus, and a bit of a time crunch left me with images that I wasn’t personally excited about. I decided to have some fun with editing, and come back to the flow setup another day. This is a top down view of a water tank containing water saturated with a bright orange mica powder. The line on the right is an acrylic wall extending into the tank; a water inlet tube is forcing water into the tank right up against the lower side of that wall, forcing water from right to left. There is a water outlet tube out of shot in the upper left, so pumping out water to feed the inlet. The flow in the tank is generated by the high and low pressure at the inlet and outlet, as well as induced by momentum diffusion between the water exiting the inlet and the surrounding water.

Shot on a Canon EOS 6D Mark II DSLR with an EF 28-135mm f/3.5-5.6 IS USM lens, at 1/4000 sec, f/5.6, 135mm, and ISO 25600. It’s possible I’ve over edited, but I think I am more happy with this than anything else I made. The high ISO and poor focus drew me to applying some manual luminance noise reduction; the green curve is totally inverted, and the red curve looks like a parabolic flight trajectory. I also applied a lens correction profile and slightly cropped the image, from 6240 x 4160 to 5600 x 3734. All things considered, I am pleased with how little de-noising I needed, and I find the inverted colors somewhat compelling. All editing was done in Lightroom Classic.
