I have been interested in movement recently and have been putting some thought into ways movement can be expressed...one way I particularly like is long exposure.
Sometimes I felt as though long exposure never really showed the full extent of the motion so I decided to emphasise this by using flour to leave a track.
This is a few of the flour motion photos I took. :)
This one below is one of me blowing the flour..I really liked the contrast of colours and distortion of this image by my face not being visible.
