Tip: One of the still backgrounds you can download from the "Missing CD" page at www.missingmanuals. com is called Color Bars. It lets you begin and end your movie with the standard, broadcast-TV color bar chart like the one shown (in shades of gray) at lower left in Figure 7-4. In professional video work, about 20 seconds of color bars are always recorded at the beginning of a tape. They give the technicians a point of color reference for adjusting their monitors and other reproduction equipment to ensure that the footage looks the same on their gear as it did on yours. Their goal is to adjust the knobs until the white bars look white, not pink, and the black ones don't look gray. If you intend your movie to be used for TV broadcast, the color bars may actually be required by the station. If not, the color bars make your homemade production look and feel as though you edited it in a $600-per- hour New York editing facility. UP TO SPEED Setting Up a Title The Color Picker Here and there--not just in iMovie, but also in System Preferences, TextEdit, Microsoft Offce, and many other programs--Mac OS X offers you the opportunity to choose a color for some element, like your desktop background, a window, and so on. The Colors dialog box offers a miniature color lab that lets you dial in any color in the Mac's rainbow. Several color labs, actually, arrayed across the top, are each designed to make color-choosing easier in certain circumstances: Color Wheel. Drag the scroll bar verti- cally to adjust the brightness, and then drag your cursor around the ball to pick the shade. Color Sliders. From the pop-up menu, choose the color-mixing method you prefer. CMYK stands for Cyan, Magenta, Yellow, and Black. People in the printing industry will feel immediately at home, because these four colors are the component inks for color printing. (These peo- ple may also be able to explain why K stands for black.) RGB is how a TV or computer monitor thinks of colors: as proportions of red, green, and blue. And HSV stands for Hue, Saturation, and Value--a favorite color-specifying scheme in scientifc circles. In each case, just drag the sliders to mix up the color you want, or type in the percentages of each component. Color Palettes presents canned sets of color swatches. They're primarily for programmers who want quick access to the standard colors in Mac OS X. Image Palettes offers the visible rainbow arrayed yet another way--cloudy, color-ar- ranged streaks. Crayons. Now this is a good user inter- face. You can click each crayon to see its color name: "Mocha," "Fern," "Cayenne," and so on. (Some interior decorator in Cupertino had a feld day naming these crayons.) In any of these color pickers, you can also "sample" a color that's outside the dialog box--a color you found on a Web page, for example. Just click the magnifying- glass icon and then move your cursor around the screen. You'll see the sliders and numbers automatically change inside the dialog box when you click. Finally, note that you can store frequently used (or frequently admired) colors in the mini-palette squares at the bottom. To do that, drag the big rectangular color swatch (next to the magnifying glass) directly down into one of the little squares, where it will stay fresh for weeks. chapter7:titles,captions,andcredits 189
