Motion bluring

[_alexbrandt_]

Hey there,

I'm doing a background motion blur effect on this picture.



I've cut out the car and applied a motion blur only to the background.
But I can see that around the car there is a halo. I think it's because the motion blur is also getting the car in the background which is underneath.



What can I do to kill that halo ?

I assume you have the Car alone on the top layer. On your bottom layer before you blur it clone into the car with the background.

Try this:
Cut the car out from background on it's own layer. On the background layer fill the hole the car left with Content Aware Fill. Now you can add a Motion blur to the background layer.

Pretty good idea but it looks like it doesn't work

Yes, I've got the car on a separate layer. I'm not sure I understand what you are saying about cloning into the car with the background.

Have a look here on how it's done best...

Since you have to make a car disappear it will be a lot more work but there's no such thing as a press and ready button in PS...

On your bottom Layer before Blurring. 2 second clone job and then blur.

Hey Eggy,

Yeah, thanks for the link. These Phlearn videos are good.
I figured out the issue had to do with the background edge of the car.
So yeah, I didn't fully clone the car out for the background but it seems to work now.

Hey there,

Thanks. Yeah I was able to do it this way.

I'm not totally done as I need to fine tune the spining blur's mask but I don't have a tablet and doing it with the mouse is real tough.

Indeed, depending on the pixels amount used for the motion blur, cloning or removing a part of the edge should be fine.
