Originally taken for the digital camera marathon in Bordeaux this week end, i wanted to make some adjustments... i quite like the effect i got.
to achieve this, just set the camera on speed priority, set 1/4s approx (you need to adjust with the ambient light) and prepare to zoom in and/or rotate the camera during the time between the open clik, and the close clic... dont know if i'm clear

it only works with manual zoom lenses...
your long exposure work is absolutely inspiring!!! I am so jealous of how things work out so beautifully and masterfully. I will hopefully be purchasing a new camera myself with a manual zoom so that I can only HOPE to attain such photography perfection!
Definate add to my favorites!
yeah , well, i was talking about the blur in itself...but nothing stops you to shoot 2 photos, one with the zoom blur, and one normal, so you can do the same process in photoshop, keeping a mask of the subject
