Step 4įor this tutorial, I set Radius Slider to 202.6px and uncheck the “Show Radius” in the view Mode section to see the selection of hair more precisely.Īs you can see from the above image, Radius slider did an amazing job in selecting fine details of hair further away from the initial selection. If you turn off “Show radius(J)” by un checking the box will show you the exact selection. Note: The above image only shows how much the selection is expanded not the exact selection.
To see exactly how much it is expanded check the “Show Radius(J)”box in view Mode section. As you move the Radius Slider to the right, the selection you made around the subject will expand. In this section, you can find Smart Radius check box and Radius slider. Just below the view mode section, there is a Edge detection section, this is where all the amazing stuff happens. For this tutorial I choose “On Black(B)” which place the subject on a black background. These modes allows us to check the result as we tweak the settings. View Mode section offers a list of views to choose from, you can choose which ever suits better. There are two main sections in the dialog box to consider : View Mode and Edge detection. This will mask the subject and opens up the Refine Edge dialog box. Using a pen tool(P) or polygonal lasso tool(l), draw a rough selection around the subject.Ĭlick on the “Refine Edge” (Ctrl + Alt + R) option at the top (or go to Menu Bar at the top Select > Refine Edge). Notice the background is not a solid background, but there is good contrast between the hair and the background.Ĭreate a new layer with solid color background just below the subject. Open up the following image in photoshop. Cut out hair using Refine Edge: Method 2 Step 1 So, this is how you can work with channels to cut out hair from the background. It’s all about which option works better. Note: Instead of using background as a clipping mask, you can simply use empty clipping mask layer and paint over the edges using same color as hair or you can use clone stamping. Copy the layer mask of the subject over to the clipping mask(duplicate sky image) and invert the layer mask (Ctrl + I) and set the layer’s blending mode to “color”. To fix this problem, we will duplicate the sky background place it at the top of the subject and right click on it (duplicate sky image) and “select create clipping mask”. The result looks really good, however if you place it against a dark background you may see a halo effect around the edges of the hair. Place a sky image below the subject layer to see the mask effect. Go to layers panel, select the subject layer and click on the “Add layermask”.
Press Ctrl + left Click on the channel (Red Copy) to make selection of it. Fill rest of the dark areas with black color. Using pen tool or lasso polygonal tool select the body and fill it with white color. Set blending of the brush to “Normal” and select white color and paint to over face… Repeat this process, until you get the result something like this…. Select black color and start painting carefully along the edges of the hair in dark or gray areas, select white color and paint over bright areas of the hair. This set up will allows us to maximize the highlights and shadows. Set blending mode of the brush to “overlay” at the top and opacity to 25%. Select soft brush, set foreground and background to black and white respectively. In this step, let’s turn the background to solid black. Set the following properties in the Levels to maximize the contrast (Make sure to retain the fine details of strands of hair). From the sample we can see, Red channel has the best contrast.ĭuplicate the Red Channel (Right click on the channel and press Duplicate Channel).īy selecting the duplicate Red Channel, open Levels (Ctrl + L). Click on each channel (Red, Blue, Green) to find which channel offers the best contrast between the hair and the background(Ignore the body, we can select it using pen tool). Open the “Channels” palette (windows > Channels). Open up the image of a woman with long spread hair on dark blue background in photoshop. Sky Cut out hair using Channels: Method 1 Step 1 Having said that, let’s start our tutorial with first method of using channels in photoshop. Today we are going to work on two images with different type of backgrounds: solid background and complex background using two different methods. Whatever the method we follow, it is important to choose an image with good contrast between the subject and the background.
It depends on the type of background the hair to be extracted from. There are many ways to cut out hair in photoshop but no single method is perfect for all sorts of images. Complex image extraction like hair is an absolute nightmare to work around with regular methods like selection tool or pen tool.
