Simulating bokeh

First of all: my name is Romano, I use to wander on Sony or Panasonic forum... and beginners one. Have a nice day you all!

I am probably discovering warm water (or the wheel), but I wrote a little script which results I like a lot ... in order to re-create bokeh after the fact. I am a user of free software, and I probably am repeating something known... but well, I'll comment on it. My idea is to blur the image on a subject-distance base, by help of a mask. You can find more info here:

So the question is: I suppose this is a known subject. Can anyone point me to "professional" implementations?

Thanks!

Re: Simulating bokeh

Hola Romano,

yes, there are some plug-ins for this effect;

topaz labs lens effects and Alien skin bokeh 2.

There are also some tutorials available about this subject.

Re: Simulating bokeh

I'm sorry, Romano, but nothing new here. It is a common Photoshop technique using Lens Blur and masking for depth map. In many cases, a gradient is also applied to the mask.

You might find this interesting.
Click any chess piece to bring into focus. You can do this with Lens Blur in PS.
