Interesting patterns in a wash in Cache Valley in Arches National Park, close to the parking lot of Delicate Arch Viewpoint.
Less than a minute after a plane passes by, the condensates in its contrails fountain up to mix with the surrounding air. Textbook case of Rayleigh-Taylor, though I suppose vortex shedding by the plane also contributes to the structure, or at least to the rapidity of the process.
As the Seattle-to-Bremerton ferry approached the Bremerton terminal, it slowed down by transferring power from the rear propellers to the forward propellers (I think). This greenish froth was created by that engagement. The terminal is to the left. It was a Seattle-Bremerton-Seattle trip to entertain an acquaintance who was in town. The ride was fun.
strobist info : on-board flash with DIY snoot+light scoop fire into white cardboard @ the back, the water is filled in stainless steel plate.
White form heads for the bubble
first of three from the sequence - could not decide which .. so put up all three
A serene fusion of nature and digital artistry, this image captures the tranquil dance of crimson flora beneath the water's reflective canvas.
The curvature of the Earth is an illusion caused by the 18mm lens setting. Taken during a hike on the mud flat of Floating Island, Utah.
Flotsam. mud on surface of slowly circulating water. Looks like it's under effects of the same forces that form the Saturn's circles.
Seems I rationalized buying some fancy Ilford film for documenting some class projects. Photography was another attempt to push the envelope, like when I turned in a thermal-printed paper ribbon generated by a calculator program I wrote to solve some homework problems. The teaching assistant gazed into the distance for a moment and said something thoughtful about how someday everyone would do their work that way.
This project was a lab that all mechanical engineering students had to do. I believe we adjusted a cone at the end of the duct, measured air pressure differences (and hence air flow) at various points inside the duct, and documented the results in a paper. Typing centered equations with a manual typewriter was not for the faint of heart.
Although I was using the same sturdy Nikon F, I don't think I owned a flash then. I must have relied on a combination of fast film and a relatively slow exposure, to work under fluorescent light in the basement of the mechanical engineering building.
