Hi , can somebody help me out ?? how can i make this effect ??

thank you

Shoot with a relatively long shutter speed and zoom out during the exposure.

for post, lens blur will probably work

thanks for the answer, and what about this pic ?? the same ?? is there a way to do this with photoshop ??

thanks

Try duplicating the bkg, distorting it, I used perspective free transform, motion blurring it and then adjusting the opacity of the layer to taste.

thank u , i will try it ;-)

Looks more to me like about a 35% radial blur filter, set on zoom. That renders the effect of zooming at a slow shutter speed.
