Loading a selection from a layer
- [Instructor] In this movie, we're gonna create these terribly exciting rays with the help of the old-school radial blur filter. And along the way, I'll show you how to load the transparency mask associated with a layer, as a selection outline. Alright, so I'll go ahead and switch back to the composition in progress here. And by way of example, I'll select this front layer, and then I'll go up to the filter menu, choose blur, and choose radial blur. And that keyboard shortcut, by the way, will only be there if you loaded my Deke keys. In any event, that's gonna bring up this dialog box right here, which by default is set to an amount of 10 and a blur method of spin. And this thing here is what passes for a preview. So you can't preview the effect outside the dialog box, you can only sorta get a rough sense of what it could look like, if you have a really super-good imagination, by dragging this thing around. Alright, now I wanna switch the blur method to zoom and crank the amount…
