*Step 2*Go to Filter > Blur > Gaussian Blur. Set the radius to 50, and click OK.
*Step 3*Now add a black layer mask to the Blur layer. Holding down the Alt key (Option on a Mac), click the Layer Mask button (circled).
This trick kills two birds with one stone — it brightens the iris and whitens the whites of the eyes.*Step 1*Zoom in so you can’t see much except the eyes. Choose the Adjustment layer button from the Layers palette, and select Curves.
*Step 2*Hold down Ctrl (Command on a Mac) and click on a bright part of the white of one of the eyes. Then use your keyboard’s up arrow key to raise that point on the curve.
*Step 3*Now hold down Ctrl (Command) again, but this time click on a darker part of the iris. Use the down arrow to lower that point on the curve. Then click OK.
*Step 4*Since we made an adjustment layer, there’s already a mask. Fill it with black by making sure that black is your background color, and holding down Crtl (Command) + Delete.Now hit B to get a brush, and paint the eyes to reveal your adjustment.
*Step 2*As in Bright Eyes step 4, fill the layer mask with black, and use a brush to reveal your whitened teeth. If you brightened them too much in step 1, just lower the layer’s opacity.
