192 CHAPTER 5 SELECTION Figure 5-22. The QuickMask button. A rough selection of the biplane has already been made with Free Select. Note Areas that are partially selected (such as the edges of a feathered selection) will have some red, but the mask will be more transparent than usual. This is not always easy to see, particularly on color images which themselves have red; but it still gives you a better idea than the marching ants would. You can make the QuickMask use a different color by right-clicking on the QuickMask button and choosing Configure Color and Opacity. So how do you use the QuickMask? It s often best to use some other tool to make an approximate selection, and then use the QuickMask to clean it up. For instance, I ll select the biplane, which you may remember from the animation back in Chapter 3. I ll begin by making a quick outline with the Free Select tool, as Figure 5-22 shows. My selection isn t very accurate; I just want something approximate. Now press the QuickMask button. The marching ants disappear, and everything that wasn t selected before is overlain with a translucent red mask (Figure 5-23). Notice that the appearance of the button has changed, to show you that you re in QuickMask mode. Press the button again, and you ll go back to seeing the marching ants. When it s time to draw on the QuickMask, Rule 1 is the same as for paths: Zoom in! You want to be able to see individual pixels, so you can paint precisely even if your hand isn t that steady.
