ALL> THIS IS ADVICE I`VE BEEN GIVEN BY SOME GUY IN PHOTOSHOP CENTRAL....DON`T KNOW IF IT WORKS....
Hi again Case, still busy playing with filters by the sounds of things...

"Is it possible to apply your desired filter on whole image or selection as a gradient or how to say it. I mean imagine I`d like to make image blurred or somehow fragmented gradually from centre to border so the effect-intesity is lowest in the centre and highest on the border [or conversely]!????"
Here is what you are after:
Quick n Dirty:
Select all, enter QuickMask mode, create a gradient with the luminosity required for the selection strength (100%-0% black, 50%-10% black etc). Return to normal editing mode from QM mode - your selection will be active and will be based on the gradient, EVEN IF IT DOES NOT VISUALLY SEEM TO BE THE CASE...Apply your filter or colour adjustment etc. Perhaps save the selection as a channel beore dropping it.
Fully Editable:
Dupe your layer, run the filter on the dupe. Select all and apply a layer mask to the dupe (either hide or reveal). Use the gradient tool to paint the layer mask (not the layer) to get the 'gradated transparency' effects you require.
This is a handy way to 'blend' two similar or very different effects into one.
Also check to make sure that 'dither' is turned on for the grad tool for this type of work, which may suffer banding.
Hope this helps,
Stephen
