These were taken in different locations. The ones on the top was the Creek Falls in the campus of Cornell University. The others were taken a couple of years back in Niagara Falls. The last one was in Groton Fall, which is a reservoir in New York, a few minutes from where I live.
The key to waterfall pictures is long shutter exposure so the water becomes silky.
The ones in the day time were taken between half a second to a quarter of of second. The night pictures were about 2-4 seconds. The camera was set on a very stable tripod and most of the time triggered with a trigger cable to avoid movement.
For the day pictures, I used 2 neutral density filters (4x and 2x) plus my polarizer (2x) to cut the light down by 8 f/stops. Then I adjusted the aperture (between f/8 to f/22) to let me fire the camera between 1/8, 1/4, 1/2 seconds.
For night pictures, there was no need for the neutral density because ambience was dark enough to slow the shutter down. Actually, in some situation, it was too low.
When I take this kind of pictures, I use manual exposure so I can control both the shutter speed and the aperture. I also made sure that the ISO setting is between 100 to 200.
Would like to hear other's technical tipbits on this subject. So, please feel free to participate.
