So this was an alternative way for some cutting out, usually people use Channels to do this. But isn't this fun to learn something different?
Let's don't get so excited, as this is only the first stage of the extraction, now we're going to need to blend this model with a desired background. So create a new layer below the "model", grab Paint Bucket (G) and fill it with black color. As you see there are still some white edges. The cut out never works perfectly, so you either have to blend it properly or just do some more accurate extraction.
Now let's go to Layers Palette, right-click on the "model" layer mask and select Apply Layer Mask. Next hold Ctrl and left-click on the "model" layer thumbnail, this should bring up the selection.
