How do you create fake bokeh in Photoshop?

I know I can use the lens blur filter but how do I make it gradually into focus? I've tried just making the lens blur a new layer and then erased with a big and soft brush but the gradient looks real fake.

If you have CS2 or better. Select the BG (I use the straight line lasso and zoom 300%), and got filters-> Blur->Lens blur and adjust to what you see fit.

To simulate realistic lens blur you need to vary the opacity of the soft brush you're using.

However, the best approach is to use a Lens Blur Map which involves the use of an alpha channel to paint blur in shades of black and white. The Lens Blur Map is then used in conjunction with the Lens Blur filter to apply blur exactly where you want it.

If you google the term "Lens Blur map" you should find lots of information.

The best method is to create a Depth Map. Some time ago rpolister wrote the definitve tutorial on this.

Link is here: http://photography-on-the.net/forum/showthre​ad.php?t=102294

Yes, it is called a Depth Map. It is simply a grayscale mask. Black prevents blurring. White gets the full blur effect. Grayscale tones are used to moderate the effect.

Ihave discussion of this in the context of comparing it with Alien Skin Bokeh in my PDF review (see pages 18 to 20).

There is an example of the result, the Depth Map mask, etc.

I'm working on a PDF tutorial to be followed by a video tutorial on this. Thanks for the stimulus. :)

Cheers,

I saw an advertisement for alien skin plug-in for Photo Shop that will make a fake bokeh.
I haven't checked to see how much the plug-in will cost.

It's $200.

I posted a review this week.

Love the look a nice bokeh effect gives to an image. The well done tutorial here seems to be an endeavor requiring several hours of time per image. More of a one-off labor of love for an occasional special shot.

If I want to apply this bokeh effect to a handful of shots on a regular basis where time is an issue it would seem that I need to bite the bullet and either get a capable lense or go to CS4 and get an Alien Skin Bokeh plug-in, simply as a matter saving time and speeding production up a bit....

Am I wrong in the time intensive assessment of this?
