What Is Monitor Calibration

Your monitor needs to be calibrated so that it accurately displays the colors contained in any given image. You calibrate your monitor by adjusting a number of different variables, which may include the following, depending on your monitor and the tools you use to calibrate The balance of colors on your monitor This balance corrects any color tints or colorcasts. Brightness The brightness control historically adjusts the black point, which is the darkest point on the monitor. 1 Contrast...

Fixing Contrast Problems with the Auto Contrast Command

The Auto Contrast command (EnhanceOAuto Contrast) sets the black- and white-point limit for you. Unfortunately, Elements doesn't offer any controls that enable you to change the Auto Contrast attributes. The command simply examines your file data and sets the black and white points based on the assumption that one-tenth of one percent of your image pixels (one in a thousand) should be pure white and the same proportion should be pure black. It should really be called Auto Black and White Points...

Set the white point in the photo

The cheerleader uniforms have what seems to be pure white trim on the top. You can use that as your target area for the White eyedropper. (The cheerleaders' white socks and shoes would make good targets, also.) Click the White eyedropper cursor in the Levels dialog box. Move the cursor to the photo and click the brightest white area you can find on the uniform. In Figure 11-14, we clicked on the uniform of the girl on the far right. (When you move the eyedropper to the photo, you can click...

Adjusting Hardware Controls on an LCD Display

What do we mean by visual calibration If you don't purchase at least a low-cost hardware calibration device, such as those discussed in the preceding section, or you need to quickly color correct some photos of the family reunion before your device arrives, you can use a software utility already available on your computer. On the Macintosh, the Mac OS X software Preferences provides you with a calibration utility called the Display Calibrator Assistant. On Windows, Adobe provides you with the...

Getting to Know the Language of Color

Color terms and definitions can be very confusing, but for this book, we use the same terms and concepts that Adobe Photoshop Elements uses and avoid all the fancy scientific stuff you really don't need to know to edit your images. Color is defined by just three terms hue, saturation, and brightness. In order to make the concept of correcting color much easier to understand later in the book, we also give you the definition of a complementary color, which means the exact opposite (on the color...

Managing Print Colors with Output Profiles

When it comes time to print your photos, part of your color-management workflow involves using the right output profiles also called device profiles . In the following sections, we help you weigh your options as you decide whether to opt for developer profiles or take a more customized and more expensive approach to profiles. With your profile on your computer, you then need to install it and make sure your printer gets the right profile information when you select your print options. You can...

Modifying Contrast with Adjust Color Curves

Without getting into how to make complex edits for contrast by using adjustment layers we go into adjustment layers in Chapter 7 , you have a couple of other ways you can modify image contrast in Elements without using the dreaded Brightness Contrast command. Elements 5 has introduced a new feature called Adjust Color Curves. This feature is a dumbed-down version of the Curves command found in Adobe Photoshop. Photographers and professional image editors routinely use Curves in Photoshop to...

Using Balanced Lighting

Balancing lighting is an attempt to make the quality of your indoor light as close to natural daylight as possible. With different light bulbs in studios and homes, the balance of your ambient light varies farther away from natural daylight, although the extent of this variation depends on the light sources influencing your environment. The color quality of light is rated as the CRI color rendering index in percentage values. A CRI of 100 percent is a perfect match to natural daylight, although...
