In this tutorial I will show you how to extract strands of hair from the background. Capturing the best out of the image subject requires patience and modest amount of time (about 30 minutes, more or less, I guess – depending how familiar you are with GIMP and how fast you do it).
Here is a picture of Eva Longoria, before and after. You can download the stock image HERE. Result varies on the time involve in editing and enhancing.
Step 4 : At this time, we would like to make a good contrast out of our image in preparation to layer masking that we will do. So, to do this, go to Color>Curves and have the most desired adjustment settings like the one below:
Step 6 : Pick the Brush Tool and make the face/skin color the same with that of the hair (which is white), and the background with black. Don’t paint the cloth. When done, go to Select>All, then Edit>Cut. Notice that the layer will disappear, but don’t worry because that was just being queued ready to be pasted. A floating layer will appear in place instead.
Step 9 : As we’ve mentioned earlier, a ‘floating layer dialog’ will then appear in the layers palette. Click the anchor button located below the layers palette and the second image below will appear as a result.
Step 10: Observe that the image above has a transparent background so we need to change the background so that the extracted hair will stand out. So create a New Layer (Layer>New…),fill it with black using the Bucket Tool.
Note : White is a better background than black, although you can choose any background of your preference.
Step 11 : Clone Tool>Clone all the grayish areas around the hair and edit the imperfections. Take your time. If satisfied, Flatten Image, then Save it.
