Multi Colored Gradient Shadow

[chaimocha]

Hello, I was wondering if anyone here knew how to recreate the multi colored gradient shadow effect on the image below. I have the black outline of the object that I want to be surrounded by the gradient, and I want to recreate it so that it is exactly how it is in the flyer below. Thank you.

I did this quickly, but it's probably something like this:

Can you give me the step by step on how you accomplished this effect?

Create three layers.

A black background layer. (Bottom)
A gradient layer. (Middle)
A Africa shape layer. (Top)



Should look like this.....


Next, highlight your Gradient layer.
Cmd/Cntrl + Click the Africa Shape layers thumbnail.

You should have a selection that looks like this....


Next, go to SELECT > MODIFY > EXPAND



Expand your selection by 22 pixels. (You might have to experiment with this step)


Next, go back to SELECT > MODIFY > FEATHER


Feather your selection by 8 pixels. ( Again, you may have to experiment with this setting)


Next, go to your 'Add Layer/Vector Mask' icon located at the bottom left of your layers panel and click.
This will add a layer mask to the gradient layer we highlighted earlier.



You should have something looking like this.......
