Curves are the most advanced way to correct image tones in Photoshop They allow you the most precise control and also the most potential for messing up your image if you don t know what you re doing The price that comes with the precision is the price of learning Figure 12-16 shows the Curves dialog box The following three areas are of most concern:

Use Curves
Let s use the Curves dialog box to manipulate an image: 1 Open an image 2 Choose Image | Adjust | Curves 3 Click anywhere on the curve to add an adjustment point 4 Drag the point with your mouse to adjust the curve 5 Move the point up or down vertically to lighten or darken the selected tone 6 Move the point left or right to select a different tone to adjust 7 To remove an adjustment point, drag it out of the window

You can add up to 16 adjustment points per curve

Increase Contrast in an Image with Curves
FIGURE 12-18 Faded image with little contrast
An image lacking good dark shadows and strong highlights is lacking contrast This gives a picture a faded appearance Figure 12-18 is a perfect example of an image that is lacking in contrast Let s use curves to fix the image What we are about to do is called the classic S curve This curve will increase contrast in an image 1 Choose Image | Adjustments | Curves 2 Click the curve about a quarter of the way from the left This is the shadow/ midtone region 3 Drag the curve point down and notice that the shadows in the image get darker, as shown in Figure 12-19

Targeting a Specific Tone with Curves
The best thing about curves is that they give you the ability to target a particular object in an image and bring out its details When you begin to experiment, you will be surprised at how much detail you can squeeze out of an image Areas that look totally black or white could in fact be harboring valuable image details The decoration on the front of the building shown in Figure 12-21 looks interesting, but the detail is lost because the camera s metering is exposed for the bright sky Let s bring out the detail in this image using the targeted method (This method doesn t really target objects as much as it targets particular tones in an image) We can then darken or lighten the tones to achieve the best results 1 Open the Curves dialog box choose Image | Adjustments | Curves 2 You will notice that the cursor turns to an eyedropper tool when it is inside the picture Hold down the mouse button, and you will see a circle on the curve, as shown in Figure 12-21 3 This circle indicates the tonal region that the Eyedropper tool is over Move the eyedropper until it is over a tone area that you want to adjust 4 CTRL-click the image (CMD-click on the Mac) to add a point to the curve 5 Drag the point down to darken or up to brighten the image, as shown in Figure 12-22
