When i apply lens blur or frischluft plugin, i get the blur in front and allso back of the image. How to make dof only in front (or only back)? I tried all the options, but i can't make it right.

If your using just a still image, you will have to use adjustment layers and masks to selectively blur areas. If you're coming out of a 3D package, it's possible to render a depth map pass to use for depth of field blurring, but I can't help much with the work flow on that one. There should be some tutorials floating around now that you might have an idea what to search for.

Here is the image. I want to blur only in front of the focus. On the image only middle of the picture is sharp. I want just small amount of blur in the front with sharp middle and background. Maybe it can't be done...

Well here is a way you can fake depth of field:

And this is a method using depth maps exported from 3D applications
