108 LESSON 4 Image Editing Basics

Working with the Temperature and Tint settings

If you’re new to color correction, the preview thumbnails provide a useful visual

reference for understanding what’s behind an unwanted color cast. Before we take

a closer look at the issue in the Expert edit mode, you can correct this photo using

the Balance controls and save the results for comparison to other techniques.

1 In the Temperature pane, click the preview to the left of the central thumbnail.

2 Switch to the Tint pane. Move the pointer over

the preview to the left of the central thumbnail.

For the Tint controls, moving by one preview

in this direction reduces the value by an incre-

ment of 25—a little too far for our lesson photo.

Instead, drag the slider to set a value of -10.

3 Choose File > Save As. Activate the option Save As A Copy. Name the copy

DSC_0378_QuickBalance.jpg, to be saved to your My CIB Work folder, and

included in the Organizer, but not in a version set; then, click Save. Click OK to

accept the default JPEG quality settings.

4 In the Adjustments panel header, click the

Reset Image button to reset all the controls,

reverting the image to its original state.

Consulting the color histogram

Let’s see what the histogram has to say about this photo.

1 Click Expert in the mode picker at the top of the Editor workspace.

2 If the Histogram panel is not already open,

choose Window > Histogram. If necessary,

set the Channel menu at the top of the

Histogram panel to Colors.

e histogram corroborates the visual evi-

dence: this photo has a serious imbalance in

the spread of color information. Rather than

a largely uniﬁed curve, there is a very marked

separation of colors; reds and yellows are

over-represented in the upper midtones and

highlights, while greens and blues are lacking.

In the next exercise, you’ll learn how to correct a color cast by adjusting the photo’s

white balance—or redeﬁning the white point, to re-calibrate the image’s color.
