Photoshop Radial Blur - preview, or marking of blur centre in image

[Hjorthmedh]

Hej!

When using radial blur on an image in Photoshop it is quite often important where the centre of the blur will be, for example to keep a face sharp but blur the surrounding. It would be great to either have some live preview of the radial blur, or if that is to gpu intensive, to at least be able mark the centre in the image with a click (instead of in the small black and white preview, which gives very low precision).

Idea: Duplicate layer, select subject and then use radial blur on the bottom layer. Your subject will stay clear.

I have added my vote, this is an ancient filter, with modern hardware one would think that it should be possible to add a preview.

In the meantime, I'll see what can be done via scripting.

@Jumpenjax thanks for the suggestions, but my idea is not for the subject to be completely untouched by the blur. I want the centre of the blur to be on the subject. And as it is now it is hard to be precise in the placement.
