GIMP HOW TO ADD HAIR WINDOWS
With the image, make sure you have the Layer dialog available (click Windows | Dockable Dialogs | Layers - or +). To switch to that mode, click Windows | Single-Window Mode. Note: I’ll be demonstrating this with The GIMP in Single Window mode. Without this Alpha Channel, the cutting from the original image will include a fill-in color ( Figure B).įigure B With alpha channel above, without below. Why? The Alpha Channel adds a transparent layer to the images. In the image with the green screen, you must first add an Alpha Channel. It’s not a major challenge, but there are a few steps, and it can be a bit time consuming (depending on the complexity of the image). What we’re going to do is remove my head and shoulders and overlay them on a background. I’ll start with a basic image of me standing before a green screen ( Figure A). With that in mind, I want to show you how to easily “key out” an image with The GIMP. I use this technique every day with The GIMP - for article graphics, book covers, and just about any image that includes layers. Few people know that same technique can be applied to graphics design for very easy image manipulation. Chromakey (or green screen) has been a fundamental element in film for years. If you work with The GIMP enough, you’ll eventually need to key an image from a green (or blue) screen and place that image into another layer. Jack Wallen shows you how to easily "key out" a green screen from a still image in The GIMP.
