I'm creating a silly anthropomorphic router by heavily modifying a product image of a Linksys router. Here's a preview.
I want to incorporate a starburst effect into the background by creating a layer with a linear white-to-transparent gradient, applying Wave and finishing with Polar Coordinates. Here's what my first attempt looks like:
As you can see, there's an unwanted artifact going from the center to the top of the layer. I'm assuming this is because the output from the Wave filter didn't tile horizontally. Is there a smart way to adjust the settings of the Wave effect so that I don't have to fix it up manually? I'm using Photoshop Elements 10.
