Is this a possibility? I am trying to acheive photographic dept of field focus where the blur increases as it falls into the background. Any suggestions would be appreciated!

Yeah this is an easy trick I saw in a book called Down and Dirty Tricks by Scott Kelby.

open your image

make a quick mask (press q)

press d to make black the foreground colour

use the Gradient tool and draw a line from the area you want out of focus to the area you want in focus. Make sure the Gradient tool is set to Foreground to Background

A red to transparent mask appears

switch back to normal mode (q again)

Feather the mask (20 is good) Under Select – feather

Use Filter Blur. I used Gaussian Blur.

It’s hard to tell if fades away with Gaussian but just try putting in a motion blur to test and you can see the blur fades in.

The method described only superimposes a sharp image and a blurred image. A gradual blur (like true depth of field) is quite different and cannot be achieved this way. This is a perennial Photoshop question since convincing DOF is hard to fake with its built-in tools (unless you do it in many steps with many different blur radii).
