[/caption] Downtown Portland Oregon on the last day of summer 2010. The cloud formations in Portland had been creating some dramatic shapes so I decided to take some shots at sunset and twilight. September and early October always seem to be the best times to get great sunset shots throughout Oregon and This time was no exception. The sun set at about 7:25 and this shot was taken at 7:54, just after sunset. Since the glare was still pretty high, I attached my ND4 along with my CIR-PL, warming filter and UV filter. Since the clouds were moving pretty fast I reduced the shutter speed to only 13 seconds. This allowed me to smooth out the river movement but also capture the clouds without getting too much blur effect. I was using my tripod, bubble level and remote switch during the whole evening since the light was too low. I had the ISO at 200 and the F stop was at F8. I was using my 18-55mm Canon lens and had the focal length at 24mm. I also had the white balance at only -0.3 since the ND4 filter had darkened the shot pretty well. Whenever I want to get the best panoramic shots of Portland I almost always go the the east side of the Willamette river and stroll down the jogging and biking path that parallels the I-5. There are several great places to set up your tripod and several areas to stop along the way.
