I've been fascinated by long exposure photography for quite sometime but only recently, have I spent the time to experiment with it.
To do this, I purchased the Nikon 14-24 f/2.8 and some Fotodiox Wonderpana filters that were made to work on this lens because it is very different from other typical lenses.
Long exposures makes you think outside the box as the world around the subject typically changes as you are taking the photo.
Since exposures can last minutes at a time, things such as clouds and flowing water typically takes on very different forms than what we are used to seeing. Clouds seem like they are stretched across the sky while flowing water takes on an ethereal calmness.
Long exposure photography is something that every photographer should experiment with as it taps into a different sense of creativity.
