Photoshop CS5: Refine Edgerefine edge (2010)
The Refine Edge is an advanced image matting tool that improves the quality of selection edges, letting you extract objects with ease. I am one of the major contributors behind this much improved feature in Photoshop CS5.
A great Youtube tutorial video is here.
The review by PCWorld :
“The Refine Edge selection dialog box has been redesigned to allow more accurate selections, especially of difficult textured edges, such as wooly clothes or flyaway hair. This isn’t to say that creating such masks are now child’s play, but with the Refine Radius and Erase Refinements brushes, along with Smart Radius analyzing the edges, the task of working on such difficult subjects isn’t as grueling. In addition, the Color Decontaminant option helps remove excess background that you might have inadvertently included in your mask–though as with all such tools, your original picture must have some differentiation in color and contrast between the background and the subject.”
