Creating a radial blur with Iris Blur

…In this movie, I'll show you how to work with the next filter in the blur gallery,…which is iris blur.…And along the way,…we'll transform this version of the Wall Street bull into this final effect here.…Now, if you're working along with me, it's probably a good idea to press Ctrl+D or…Cmd+D on the Mac in order to de-select the image.…Then grab the bottommost layer, which is that smart object, and…drag it above the static back drop layer.…Because this time, we'll be applying Iris Blur as a smart filter, and we'll do so…with that smart object selected,…by going up to the Filter menu > Blur Gallery > Iris Blur.…

And the idea behind Iris Blur is that we have a radial focus effect.…So the location of the pin indicates a 100% focus,…as we're seeing up here at the top of the screen.…And then the ellipse indicates region of blur.…Which in our case is set to the default value of 15 pixels.…So anything outside the ellipse is blurred to 15 pixels.…And anything inside the ellipse gradually fades to a 100% focus.…Now you can modify this ellipse as much as you want.…
