I normally do highly realistic, very sharply focused images, a lot with focus stacking, so this is completely new to me. Yesterday evening I went with a group to the Arnold Arboretum in Boston to experiment with ICM (intentional camera movement), where you use a long exposure and deliberately move the camera to create abstracts. These three were done with an ND 8 to allow me exposures of 0.6 to 1.6 seconds.
C&C particularly welcome, as these are from the first batch, and I have never tried anything like this before.
