Hi,

do somebody know a plugin for photoshop or a tutorial that helps me to create a motion blur, so that objects are looking like moving in one direction and not shaked like it looks per standard photoshop filter?

Attached a simple example of a big black point. I'm looking for a visible point with motion blur in one direction only, like motion lines at cartoon sketches. In real life this could be done per shooting a photo with flash light and long exposure time (flash at the end of exposure time)



Here an image that I found at the web, that show a blur like I'm looking for. (not a nice example)


But here the ball show it quite good


Best would be, if a vector line for the motion could be drawn and used by a tool for motion blur creation.

... here I play a little with the "wind" filter, but this filter give me not enough control (direction, intensity, effect). The filter show what could be done in this direction of effect. Do somebody know a better wind filter?

The M-blur options in Photoshop are limited for sure. There used to be a plugin callled Velociraptor (or something like that) that gave you some other options.

The best way that I know of now is to copy your object to a layer and do the motion blur on that. Then move it over and/or stretch it in one direction and mask/erase the side you don't want. Usually you then need to also mask out the trailing edge of the sharp version on the lower layer so that the edge fades into the m-blur. Bit harder this way, but not much and lots of control.

Adding curvature has to be done as a post-blur transformation, which is pretty easy to do with the image warp tools in Pshop, but it's never the same as real 3D blur.

The only other way I use would be to tweak the settings of a smudge brush a bit and then do it by hand. I often do that with smaller things and to create variations in direction to look more like real 3D motion blur, but for bigger elements it can be difficult that way.

Hope that helps.

Just an idea

In the first exemple you give, you could use the black point to mask the left point of the blurred one?

Thank you for the suggestions. I found the plugin here:

and will test it.

hi micha
i'd be interested in your results. can you post them here if it works?
cheers, kami

The velociraptor demo don't allow to see the result in original resolution, so it's not easy to say, how good it works. Here a screenshot (seems to be a quite old tool):


And here a hand made version:

I copied the layer, set it to "darken", apply a motion blur and move the layer to the left. It's a pity that PS don't allow to motion blur along a curve.
