Third, select Image-Calculate command.

Four, pop up the calculation panel, select "Overlay" or "strong light" mode in the blending mode, can make black area darker, white more white. Are you sure.

When determined, an alpha channel is generated (in short, when the selection is saved after the calculation, Photoshop converts the portion of the selection to white, the rest to black and into a new channel, which is called the alpha channel, which makes it easier and more accurate to select the desired selection. Once did not choose good, can also calculate again, generate ALPHA2, ALPHA3, etc., no longer repeat). White hairs are the objects we want to pull out, so we have to dispose of them outside of the grey or gray. With the foreground color black, click the Paintbrush tool, soften the angle 30 pixels, opacity about 30%, smear in the excess white and gray areas to make it black and disappear. The upper right corner and the tip of the border to the place with a smaller brush smear, not blunt.

When applying to the tip of the hair, be sure to enlarge the graph n times. PS How to say are deliberately, no less than cross stitch.

On the cheek, apply a soft-angle brush less than 10 pixels.

You can replace the foreground color by clicking the curved bi-directional arrow icon in the front background color thumbnail below the left-hand toolbox. Press the shortcut key x also line, the brush is now white, select 20 pixels, opacity 100%, in the head smear, are processed into white.

Nine, good. We're going to choose a white-haired constituency now. Click the select-Load Selection command and you will see the cute ant line, which is the selection.

Ten, dot RGB point layer, back to the layers panel, from the dark behind the scenes to the bright front desk. By pressing the CTRL+J key, the white hairs are keyed out and a new layer is created, Layer 2.

Xi, at this time we pull out of the white in fact at the tip of the hair is gray, the following two layers point off the front of the eyes you will find.

Create a new blank layer (under the Point Layers Panel), click the foreground color thumbnail to pop up the color Picker panel, and click one of the colors to determine the mouse. Then press the combo key alt+delete to fill the foreground color onto the new layer.

12. At the layers panel, drag layer 1 to the top, create a black mask for it (ALT + Add layer Mask button), and you'll see a white-haired figure keyed out to pull the face out of the person. Create a black Mask many friends will forget one of the most important step is to set the foreground color to black (point curved double arrows or X-key substitution, if the foreground color is not black is the other color, the D key to restore), only in order to use the Eraser tool (the foreground color of the following figure has not been adjusted). After the foreground color is black, click on the Eraser tool and use the soft (standard or soft) eraser tool to first wipe out some of the dirty places, circles, in the previous step after using the color Scale tool in Layer 2. Other places to clean. Then go back to the masking layer, with a soft eraser of about 30 pixels and a 40% opacity on the black tiles, gradually revealing the original skin color.
