The rain rain rain in California means that the waterfalls are gushing! I went hiking in Cataract Canyon with the Bay Area Phography meetup groupĀ after the rain and got some great long exposures. Used a polarizing filter to cut down the reflections. I wish I had an 10x Neutral Density Filter to get some really long flowing rivers, but losing two stops to the polarizer and shooting at f/16 and higher gave me a four to ten second exposure, perfect to save some detail in the darks behind the falls themselves.
