Photoshop CS3 for Screen Printers- P336 Part I / The Photoshop Interface You can display as many palettes as you like or will fit on your screen. If your screen resolution is set to a low resolution like 800 x 600, you’ll probably want to collapse most of the palettes. In fact, at that resolution, you may not even be able to see all of the tools in the toolbox. A higher resolution lets you see more items on the screen, and that’s better for Photoshop. What you see will differ depending on your screen resolution; however, this image does give you a feel for how your screen should look. If your screen resolution is too low to handle everything in the Photoshop interface, try changing it to something higher, such as 1152 x 864.. Note: Although you should use the highest resolution that works for both you and your computer, many of the screen shots in this book were taken using a lower resolution so they would be more readable. This might cause some minor differences between the screen shot and what you see on your screen, but for the most part, you won’t notice any difference at all.The Default Palettes The default palettes, as shown in Figure 3-1, contain two or three sepa- rate palettes that are docked together. The first one contains the Navigator, Histogram, and Info palettes. Navigator, Histogram, and Info Palettes These three palettes are docked together because they are each used for obtaining information about an open file. The Navigator palette allows you to quickly change the viewing area of the file on which you are work- ing. You can quickly zoom in and out and view additional palette options. The Histogram palette lets you view the Histogram of the image (more on that later), and select sliders for various color choices like RGB, CMYK, and Web colors. With these sliders you can make adjust- ments to the color levels and tones. The Info palette displays information about the color that’s directly underneath the location of the mouse pointer in the image, and displays additional information depending on the tool chosen. As a graphic artist, Chapter 3 / The Palettes 37this information can be quite useful when matching a color or workingbetween different color models. The Info palette offers other information, including the following:n X and Y values are shown when using the Crop tool, the marquee tools, the Zoom tool, and the Line, Pen, and Gradient tools.n Readouts can be configured to show values for actual color, proof color, grayscale, RGB color, web colors, HSB, CMYK, and lab colors, and total ink or opacity. There are two sets of readouts, both of which can be set.Let’s explore these palettes and view colors for an RGB file:1. Open the Ducky.tif file from the Samples folder stored in the Adobe program folder. (This procedure was detailed in Chapter 2.)2. Make sure the Navigator palette is open, as shown in Figure 3-2. To verify that the default palettes are available, choose Window> Workspace>Reset Palette Locations. For this figure, I’ve dragged the palette closer to the image. Figure 3-2: Using the Navigator palette3. Click the Info tab to access the Info palette.38 Part I / The Photoshop Interface 4. Click the arrow in this palette to see the additional options, and choose Palette Options. 5. From the Info Options dialog box, change the first option to RGB Color and the second to CMYK Color. Click OK. 6. Select the Eyedropper tool from the toolbox. Remember, you can also select the Eyedropper by pressing I on the keyboard. 7. Hover the Eyedropper over a color in the image. In the Info palette you can see the values for the color. Move the mouse around to see the values of the other colors. Check out the setting when you hover over the white part of the image. Notice the RGB values are all at 255 (that’s the highest). Now, hover over the black part of the image. Notice the RGB values now lean toward all zeros. That’s the lowest number. 8. Shift+click on the image to add a sampled color to the Info palette. You can then compare the colors from this selection to other areas of the image. You can add up to four sampled colors here. This is quite useful when you need to know if one yellow in an image is pretty close to another yellow in the image. 9. Click on the Navigator tab to open the Navigator palette. Use the slider bar to zoom in or out, or click on the zoom icons in this palette. 10. Click the Histogram tab. Notice the Histogram chart. A histogram is a graphical representation of the color data in the image. Click the arrow in this palette and choose All Channels View. While this is beyond the scope of this chapter, after learning how to read these histograms you can tell if a photo is underexposed or overexposed (among a multitude of other flaws), and use the tools in Image> Adjustments>Levels to correct what’s wrong. Go ahead and open Image>Adjustments>Levels to view the tools, and move the slider to see one of the ways you can use levels and histograms to change the image on the screen. 11. Select Window>Workspace>Reset Palette Locations before continuing. There is much more on colors later in this book; this chapter is only meant to familiarize you with the available palettes.
