How to Blur the background of a selection following a gradient

Hi All guys

I would like to do a filter wich can reproduce the attached Image done with Phoshop blur and a gradient mask

The problem I have is the "selection "behaviour in FF who can't allow to blurr the selection.( it is like you blur a selection mask

I didn't found any way to take the background ( selected in photoshop ) and blur it following a linear gradient form the bottom of the image ( no blur ) to the top of the image ( blurred)

Do you have any idea / advise to do so ? See Image Here

Thak you in advance for your kind advise

All the best
Jean Luc

Heres another version with a Tone Curve added for positioning of the gradient...
Also the selection is not affected by the blur..So you can select the model and everything else will be affected by the blur...

i havent looked at CF's way of doing what he did, but i can tell you one way to do a background blur filter IF your foreground is brighter or darker than the background. you simply make a mask filter based on light/dark and then blur the one you want blurred.

there's probably other ways to do it, maybe based on rgb values or something else.

also, if you have paint shop pro, there is a background blurring tool that was put in after about version 9 or 10.

Your filter is VERY good !!! Thank you

Now I'm trying to understand how it works ... this is another problem ) The way you use frames is very interesting ...

I realize that this king of filter is maybe a little bit to hard to undersand for a fresh newbie as me )
