This photo was made years ago at near Julia Pfeiffer State Park at Big Sur. I wanted to make the waterfall and the waves look like cotton candy. In order to do this, I used my ancient Canon 40D’s lowest ISO (100) and then “stopped down” or closed down (using the smallest aperture/largest f-stop) to f/32. This automatically allowed me to use the slowest shutter speed possible. In this case, two and one half (2 1/2) seconds.
The camera was mounted on a tripod because it would be impossible to hand hold a shot that long without getting motion shake-caused blur.
I didn’t have any neutral density filters with me on this particular trip, but I did have a circular polarizer. That automatically knocks down about two stops of light. Had I brought an ND (which blocks light) I could have caused the cotton candy effect to be more pronounced because I could have used a slower shutter speed.
I know most of you will see nothing new here. But remember, there are new people finding a love for photography every day and they can use the help.
