![]() The hair should be already white, and everything behind the hair should be dark gray or black so you dont have to use time to get the hair extracted. You don’t have to paint the hair! Thats the point of this technique / tutorial. You can move the background-layer above all layers and set the transparency to 20% or so to see what parts you have to paint. To make it easier to correct mistakes you should create an empty layer above the highpass-layer and paint on this layer, when done merge the layer down. Now you need to take a brush and paint the body of the person / object with white. We’re now done with the highpass filtering. Its important thyt you get nice contrast in the hairs area. We’re aiming to get a good clearly vivisble contrast. This step can vary when you use a diferent picture. ![]() Then choose Brightness & Contrast from the same menu. ![]() The go to Colors / Curves and apply a soft S-curve as seen on the image below. You should have something similar to my picture now.Ĭlick the right mousebutton on the layer in the layers dialog and choose “Merge down”.Ĭolors / Desaturate (average). Set the layer to 50% transparency in the layers dialog. On the top layer use Filter / Gaussian Blur: 18px. I use a picture of a well known celebrity.ĭuplicate the background layer 2 times, you should that layer 3 times then. Open any picture that contains a big shot of a person / celebrity / whatever. The point of the techqnique is that you'll save lots of time for the difficult hair part, because when you do everything right the hair is extracted automatically. We need to simulate this filter because there is no filter in GIMP that does this for us. The method i use for this is called highpass. But sometimes you need perfect masking that includes for example the hair of a woman. Motivation There are several methods to extract/mask objects or persons from the background.
