Back in early October I wrote a short post entitled Control the Light where I talked about using a Singh-Ray variable neutral density filter stacked with a warming polarizer to obtain a unique long exposure “look” in my images. While this technique works great, it can be a pain to setup properly and the stacked filters tend to vignette my wide angle lenses.
Recently, Singh-Ray introduced their new Vari-ND-Duo filter which combines their variable neutral density filter with a circular polarizer filter in a single, very compact unit. The new Vari-ND-Duo is much easier to use and prevents the vignetting issues I had experienced before.
I took this shot at the McKinney Falls State Park while waiting for a group of families to clear my line of sight to the falls. Using the Vari-ND-Duo and my camera set on full manual, I was able to achieve this “motion”effect with a 6 second exposure.
