I bought a ND filter back in February and have had it rattling around my bag ever since, but as this weeks theme is long exposure I setup the tripod, put the filter on, and got MissBLP to jump with me over the fields.
Oh wow, you actually managed both the themes I had in mind for this week's competition. I was hanging on Long Exposure and Things In The Air. :-) It became Long Exposure of course, but you have gotten them nicely combined :-D Cool!
Basically, sunglasses for your camera!
