Another from a nice day at the brook. This could easily have been titled with chaos as the others but the change of direction in the flow caused by the rock was what really got my attention.
As you might guess, it took a fair amount of experimentation with the exposure time to get something that looked somewhat organized. 0.6 secs at ISO 400, f/8 ended up being the right combination. 70-200 + circular polarizer.
I don’t usually mention clicking the image but if you do it gets a bit larger and the flow shows beter.
