OK... this will probably make no sense so I'm going to try to ask this in the simplest way possible...bear with me! ;o)

When you are applying a radial blur to an image, you can choose where to "center" the blur and have it radiate outward from that in whatever size/intensity you want. When you look at it, wherever you locate that point, the radial movement goes around it parallel to your screen/you as you look at it. Like flat on. Is there some magical way to change the angle/tilt/plane of the radial motion, like tilt it backwards or forwards? Take for example this picture I took yesterday for my PaD...

I applied a radial blur, but didn't get exactly what I wanted because the movement is too parallel to me, rather than tilted backwards to match the angle of the merry-go-round.

Gosh I hope this makes some sort of sense what I'm asking. I'm really not completely insane, I promise! ;o)

Total stab in the dark here: would it be possible to use the distortion tool to pull it out of shape and therefore create the illusion you're after?
(oh my.... my mother said never to answer a question with another question..... ooops)

I understand what you're saying. I'm certainly no photoshop expert, so my advice could be way off.. especially since I've never used this tool.. but I would think you might want to create a new layer somehow and apply the blur to it, use the transform feature to tilt it back a bit, and then erase the parts of the layer that you don't want tilted (and let the original show through)..

if that made any sense.. haha. i could be way off, though.

edit: oops, was just slightly beat to it!

brian's right, what you could also do is distort your picture in another layer then apply the blur then re-distort it back to the normal view...should work.

Whew... I was afraid I was babbling incoherently (imagine that)! ;)

I'm going to try that and I'll post the results to let you help me decide if it works or not. Thanks so much to all of you!!!! :o)

edit to add....it will be after the baseball game before I get to it ;o)

The cheat is to expand your target image to circular [square] proportions, apply the radial blur, then re-compress the image to its correct perspective. Not perfect, but more effective. It's also better if you overlay this over the original shot [duplicate layer] rather than do it on the only layer in the document, since there is image degradation in the process.

To get that filter to work both the subject and the lens have to be on a 90 deg perpendicular plain. I donĂ¢€™t know of anyway to skew the filter so you would have to skew the image, degrading the quality. One other option would be to duplicate background layer and using the marquee tool select the subject then invert and do a manual motion blur keeping the subject in stop motion then blending with overlay.
That may work although a little more time consuming.
