Move rulers to split your image depending on the brightness and the type of object (e.g. hair ≠ shirt). This is per se not so different from the previous method, but it might be more convenient because you can see the result of what the outline will look like just by moving a slider, rather than changing a threshold and fuzzy-selecting multiple times. You should have to spend about 20 minutes on a complex hair subject and 10 minutes on a simpler one. Manually blur and partly erase them (especially the tips) to make it all a bit subtle. Note that you can draw many individual ones by shift-clicking to start new paths. You may want to copy the mask to a separate layer again to see the masking area from the original picture and draw paths for some significant individual hairs. Use the x key trick to swap between foreground (black) and background (picture) to quickly add and remove pixels to the mask. Unlock pixels and directly edit the original image mask to improve it. Create a pure green background in a separate layer to best assess the result. Once you're just about satisfied, set the green layer alpha to selection, add a layer mask to the original picture mask and initialise it to the selection.Decrease the opacity of tools to subtle levels. Likewise, refine the mask with tools such as the eraser, the paintbrush and even the smudge tool. Note that hitting on the delete key multiple times expands the deletion area, which can be useful at times. You may want to decrease the opacity of the green layer and further fuzzy-select holes between hairs.Don't hesitate to play with the layer's opacity. Use different types of brushes with different hardnesses (go softer for hair). This way you'll be able to adjust the opacity of the green layer to refine the mask comfortably. Create a new, transparent layer, invert the selection and fill it in pure green so the object to clip is covered in green.It's not a problem to miss out hair, we can always fix that later by selecting portions again or directly painting the mask. Don't forget to select hair-enclosed holes too. Also, you may want to feather edges around hair-like subjects. It's quite convenient to keep the threshold rather low and repeatedly click on areas of the background which you want to select. But it's just as simple to select the background if it's homogeneous. Photoshop tutorials will have you use another tool I can't remember the name of to actually select the object to clip instead. We don't want to be tempted to uselessly spend time on portions of the image we'll get rid of eventually.įuzzy-select the background. And that's something which you can very well do with GIMP too. Photoshop provides specific tools for this too, but don't be fooled by Adobe's claims and various other tutorials: these tools aren't magic and you won't get a good result unless your original image was simple to mask in the first place, or unless you invest a lot of time semi-manually polishing your result. Some commercial solutions come with plug-ins for this purpose. Raster image graphics editors are traditionally used for the purpose of cutting objects off an image.
