Adding motion blur

Anyone know how to add a little motion blur behind someone to give the impression of movement? CS2 has a motion blur filter but it adds blur to the left and right instead of just the right like i'm after. The photo i'd like to do it to is below.

I duplicated the background layer, applied a motion blur to the new layer, added a layer mask and filled it with black, then went in with a small brush and painted white onto the mask where I wanted the blur to show through. This was a quick job, but with a little more patience and attention to detail you should be able to get exactly what you're looking for.

Thanks JDB i'll do that this evening

Hi Tim!

Had a little play with it for some 5 minutes. Used the polygonal tool to select the areas I wanted to blur, applied some feathering, then used motion blur set at 0 degrees. It's a bit rough but if you slow things down a bit you can get better effects... a couple of peoples faces were blurred out....

Edit... oops...:o the file was too big to attach. Uploading it to photobucket... man, I should find a job and upgrade to "broadband"...

No problem! Glad I could help. I'm always learning new things from what you post, so it's nice to be able to give back a bit

I was really looking for the lazy mans way of doing this, like only doing the motion blur in one direction, but a mask is pretty easy thanks

Why not something like this, with the "camera" panning instead of being statonary.

interesting, great input... I feel like ET or the is the robot and that guy from India. I can't remember the name of the movie... Let me think ET phone home. not that movie, the other one... Nice photos looks like a happy, happy time...

Great idea Radtech, I think i'll offer all three versions of the image to the customer - though maybe that'd confuse them

Hi Rad,

Do you mind show us what you did to create that effect? That is something in Photoshop i wish to learn. TIA.

I did a mini-tutorial in THIS THREAD a while ago. Rather than retyping the whole thing, I will just give you the link.

Cool! Thanks very much.

The real trick to the motion blur:

The one thing that you can do to make the motion blur effect much more realistic is to remember this: When you pivot a real camera (Pan) you scribe an arc. That means that the more distant an item is, the greater it's apparent motion. On the sample shot, I used only two areas, the grass, white fence and "racing club" sign were blurred 10 pixels. The hills and the sky were blurred 30 pixels.

If I were doing this shot for my own uses I would use at least 4 or 5 different "bands" of blur, with each one at least doubling the one closer than itself.

In the example below, as spot located at distance 1 would have appeared to have moved 1 unit. At distance 2, 2 units, and 3 units at distance 3.

Thanks for that Radtech
