Looooooooooooooooong exposures...
I've had a great time over the last month playing in the #steemitphotochallenge hosted by 
!
Steemit Photo Challenge, Week #66
This week's theme is Long Exposure, which happens to be my favourite type of photography! Most of my very best photos have been long exposures of some kind or other. It was hard to pick three for the contest, but I decided not to overthink it - here are my submissions:
Alabama Hills
In California... on the eastern side of the Sierras (Mt. Whitney is in the balckground). This was a long exposure at night (a bright, moonlit night). We set the cameras up and my friend drove the truck back and forth a few times as I triggered the shutter.
Big Cottonwood Canyon, Utah
Long exposure during a lightning storm from Guardsman's Pass. Clouds, cars, colours and electricity! 146 seconds.
Bear's Den Falls, Massachusetts
1-minute exposure of autumn leaves swirling in a pool. The currents that form beneath waterfalls like this often form a vortex, but it takes a long exposure and something colourful in the water to make the pattern appear. I used a 10-stop ND filter for the long exposure and a circular polarizer to darken the water.
