4. Use the Quick Selection tool and Refine Edge to select the lion. Choose Selection
as the Output To method in Refine Edge (as we did earlier with the athlete cutout),

of this layer by going to Layer > New > Layer via Copy, and then choose Layer >
Layer Mask > Apply ( Figure 1.48 ) . (This keeps the original safe in case you make
a mistake.)
