Not sure what you mean but actually in John Blakemore's early images it's the intermittance as apposed to a continous long exposure thats important.

The image on this site's homepage by Les McLean is not the best example of the technique as its not far different to the result from a continuos exposure. That may be a little harsh as we are ony seeing a low res version.
I have used the technique myself and it produces amazing images, if I had a larger scanner I'd scan an exhibition print but at 20"x30" it's too large for an A4 scanner.
Now coming more upto date John Blakemore has still been using similar techniques for still life images, adding and subtracting obects during the exposures . . . .
