Depth of Field
Unfortunately the Blender depth of field has problems that we would have to deal with...most likely so I am looking into another way to get DoF...which I would probaly do with After Effects. Here I have an image, and a greyscale image that would represent areas close and far from the camera lens.
I would use the greyscale image to regulate the focus distance...sadly I am still having problems. I am going to try to look into the stuff about the new Z buffers in Blender...which should help.
