Use a big brush size (relatively hard with some soft edge)
#Gimp tutorials face skin#
Now we paint the parts that don’t need masking with white (the skin and the hair where’s no background). The green channel often contains details and contrasts, so the hair is masked even better. I have also amplified the red color tones (the hair contains many of them and become brighter) and reduced the blue tones so that in sum the background doesn’t become brighter.
It doesn’t matter if the image becomes granular or if the face looks strange (like on the screenshot). The fine hair details should NOT blur with the background. It doesn’t have to be perfect because in the next step, we’ll do some fine-tuning.
Try to make them light gray while the background (here: gray) should become darker or stay at least the same. Pay special attention on the fine hair parts. Now it is important that we achieve a good contrast between the background and Jessica’s hair.įor this you have to find out the individual settings for each image. You can see in the preview that the image doesn’t have colors anymore. Now click on “Monochrome” so the image will become grayscaled. The best way to do so is using the channel mixer: The next step is important: We reduce the layer’s color by disaturation. To do so, we have to create a copy of the background layer first:Ĭlick on the “Duplicate layer” button in the layer dialog or press Ctrl+Shift+D. Now we want to create a detailled layer mask that contains all fine details of the hair. On the image, you can see the fine hair strands and the mat gray background. This masking technique is good for strands of hair or to replace the sky. This tutorials shows a way that produces good results for fine details like strands of hair, especially for portrait photos with a simple background. Motivation There are many ways of masking objects with GIMP.
