I thought i would post one of my really old SX-70 Manipulatives. Amazingly enough it was shot with my two children lying on the concrete near the pool to warm up from the chilly water.
This really is a cool technique! I do with the kids were a bit more in focus - I tend to like at least one element of an image to be in focus when everything else is blurry. Still, for the type of effect it is I am not as picky as this is a really neat image anyway.
