Hey Guys... So, for the longest time I've been removing backgrounds in photoshop by using a combination of the paint bucket tool and eraser tool. But, this is really tedious and I've always meant to ask someone if there's a better way to do this.

I want to remove the background behind a model so that the edges around him look crisp and clean (such as on magazine covers). See the image I attached below (I want to isolate the model as they've done, with clean, crisp edges). Any suggestions?

Thanks guys :-)
