Hi, I'm trying to find out how lens blur algorithm is working. For example it is implemented in Photoshop: http://www.computer-darkroom.com/tutorials/tutorial_9_1.htm it's also known as Bokeh effect: http://en.wikipedia.org/wiki/Bokeh Does anyone know how can I implement this algorithm? Any links will be highly appreciated. Failed to find anything useful in google. Thanks in advance. -- Best regards, Pavel Tumik mailto: pav...@gm... |

I'd just get your standard Depth of field functions working, then change the blurring stage. It does seem that the only real difference is that intead of being a gaussian blur, it's just a case of a shape blur. If you can follow a depth of fielf "howto", then you should be able to adjust the final result quite simply. 2008/11/24 Pavel Tumik <pav...@gm...> > Hi, > I'm trying to find out how lens blur algorithm is working.
