Decided to play around with my Variable ND Filter during a church Men's Retreat at a military recreation area in Northern Okinawa (Okuma for those familiar with the area) this weekend. Without the ND Filter, there's no way to get a .5 second shutter speed in the middle of the day. One would think this was taken later in the evening after the sun went down, but adding about 5 stops of reduced light can give you interesting options even during the day. The varialble ND filter I have has the ability to go from 1-10 stops of reduced light, but it can do some strange effects (put a black cross in the middle of the frame or darken the sides) as you rotate the filter to add darkness, especially on my super wide-angle lens. In this case, I was using my 24-105mm 4.0L lens so the filter works without issue.
As for the processing, I was experimenting with some new software for editing photos. onOne Software has been a real joy to work with. It's masking and layers are easier to use than Photoshop and for the minor things I'm doing, it's just as powerful. In this photo I converted to B&W and toned it the way I wanted, then brought the opacity of the B&W layer lower to show just a very little bit of the color layer underneath show through.
