Using the Refine Radius tool

In this movie, I'll show you how to use the refine radius tool, which is a tool…that's available to you exclusively when you're working…inside the refine edge or refine mask dialogue box.…So here I am looking at that same image from the previous movie.…I've applied a radius of 20 pixels and turned on the smart radius check box.…Now what we need to do is go ahead and scroll our way up…to the hair, maybe zoom out a click because I'm a little too close.…Now notice that as…I'm moving my cursor inside the image window it's a brush.…And that brush represents this tool right there, the refined radius tool.…

Which allows you to brush more radius into your image,…that is your brushing in a larger area of edge detection.…You can change the size of your brush up herein the options bar.…Notice in my case it's set to 25 or you can press one of the square bracket keys.…Now, on a Mac, you're going to have no problems.…On Windows, it's a little…tricky because the values get stuck and so Photoshop isn't paying attention to you.…
