Using Alpha channels to produce photoshop masks.

Photoshop Quick tip

Quick Tip - Photohsop ( Moderate to Advanced ).

Step 1: Channels Palette
The first step in masking out hair is to open you channels palette. Now duplicate the channel with the most contrast between the hair and background.

Step 2: Duplicated Channel
Photoshop Quick tip
Select the channel that was just duplicated. Using the paintbrush tool begin to fill the image in with black to create a silhouette. Take your time, the silhouettes edges need to be clean. Make sure you don’t cover any of the strains of hair.

Note: If the background on your image is more complicated use the Color Range tool from the select menu to select the finished black silhouette. That should give you a nice mask. I plan to add a Part 2 to this tutorial demonstrating how to do that in more detail.

Step 3: Completed Mask

You should now have a mask that looks something like this. I inverted this mask just to show the details in the hair. Finally apply the mask to your image and your done. If you apply the mask as a layer mask it will allow you to go back and edit the mask if needed.
