I know this probably wasn't created in photoshop, but i would like to kno how to achieve a similar effect in photoshop if possible

http://www.apple.com/ipodnano/ads/

I don't want to animate it - just do a still shot - I'm fairly fluent in photoshop, but just can't seem to get this right!

In case the link doesn't still work, basically i want to achieve an effect of an object on a black background where it looks as if the object has been moved quickly in front of a camera with a slow shutter speed and the glowing points of the object have burned themselves into an after image

For example, you know how if someone is moving a torch quickly and you photograph it (or even just stare at it) the after image effect gets burned into the still image.... Basically i want to simulate a slow shutter speed with a few highlighted objects in an image...

(If that makes sense to anyone i'll be amazed!)

would anyone be able to point me in the right direction as to how to achieve an effect like this- are there any plugins which could help as well?

I've already tried with motion blur and then liquify, which is almost good (ish) except it doesn't seem to distinguish between glowing points of the object being moved and just looks like it's been smudged!

Any tips would be gratefully appreciated!

I'm working on another project right now, so don't have a lot of time, but here's my thoughts:

Start with the base image. On a new layer draw a path which begins at your glowing points and goes from there. The path is going to be the glowing trail. Stroke the path with a color sampled from your glowing points. Because you've put this on a new layer, you can now add layer effects (inner glow, outer glow, etc) to the trail without affecting the base image. Lastly, add a layer mask with a black-to-white gradient to "fade" the trail and glowing effects.

This is undoubtedly oversimplified, and will require tweaking to get it right. I wish I had time to experiment and give more specific advice. Still, that's the process I'd try to follow.

I hope this has been helpful. Let us know how it turns out.
