Making Over Diffuse

One of the most common makeover adjustments you'll encounter involves the adjustment of the highlight value of an image that has a diffuse, white, highlight. Here is an example:

1 Open the image Mark_ Tauna_Loomis_GS_300.tif image.

You'll notice that this image (available for download from the Web site associated with this book) looks a bit flat and the white area (Tanua's shirt) looks a bit dingy.

2 Choose ImageoDuplicate to make a duplicate copy.

Always, always work with a duplicate copy, rather than your original.

3 Choose WindowoInfo.

The Info palette makes an appearance.

4 Click the Eyedropper icon on the left side of the Info palette and select Grayscale from its contextual menu.

The Info palette can now measure grayscale values as percentages of K (as in CMYK, where "K" stands for "key" but really means "black) when you move the cursor over the image.

5 Choose the Eyedropper tool from the toolbox and set its sample size to 3 by 3 Average in the Eyedropper tool's Options bar.

This allows the Eyedropper tool to measure and display an average grayscale value of nine pixels in a 3-by-3 matrix. Doing so gives you a clearer sense of how it looks than a single pixel would.
