defocused images

I saw the Tony Sweet's website 'TONY SWEET PHOTOGRAPHY INC.' It was pointed out by Ed Vatza in macro threads. Question: how does get similar images? full ouverture of the diagframm and..what else? intentional blurring?
thank you to everybody if would answer. Valerio

My bet is on some sort of post processing routing similar to many of the actions you can find out and about.

There are some that simulate the LensBaby look.

Of course, he has to have great images to start with .

Edit: I just took a deeper look on his site, and there is a lot of reference to the LensBaby, so that's a good place to start.

He uses Lensbaby and also Nikon's multiple exposure capabilities to blends images in camera. The water blurs he uses ND filters and long (maybe 10 secs) exposures.
I recommend you buy his DVD where he explains all his techniques. A+++

I didn't realize he was so close to me... I'll have to look him up some day.
