To add color to a grayscale image

You can colorize an entire grayscale image, or select areas to colorize with different colors. For example, you could

select a person’s hair and color it brown, and then add pink to their cheeks after making another selection.

Note:

If the image you are coloring is in grayscale mode, you must convert it to RGB by choosing Image > Mode > RGB

in the Editor.

1

In the Editor, choose Enhance > Adjust Color > Adjust Hue/Saturation, or Layer > New Adjustment Layer >

Hue/Saturation to work on an adjustment layer.

2

Select Colorize. If the foreground color isn’t black or white, Photoshop Elements converts the image to the hue of

the current foreground color. The lightness value of each pixel does not change.

3

Use the Hue slider to select a new color if desired. Use the Saturation slider to adjust the saturation.

4

Click OK.

To change a color image to black and white

The Remove Color command converts the colors in the image to gray values by removing all the saturation from the

image. It assigns equal red, green, and blue values to each pixel in an RGB image, so the image is still in RGB mode.

The lightness value of each pixel does not change. The Remove Color command can also be used on a selected area

to change only that area to grayscale.

This command has the same effect as setting Saturation to -100 in the Hue/Saturation dialog box.

❖

In the Editor, choose Enhance > Adjust Color > Remove Color.

Setting press target values

Setting target values for print

If you are preparing an image for printing by a commercial press, you can set target values for shadows and

highlights. The values that you use depend on the ink percentages that the press can accommodate. For example, if

you know that the press can’t reproduce detail in shadows at an ink percentage greater than 90%, set the target value

for the image shadow to 90%. Similarly, if the press can’t reproduce detail in highlights at an ink percentage below

5%, set the highlight value to 5% or higher.

When you set your highlight and shadow points, Photoshop Elements compresses the tonal scale so that detail in

shadows and highlights is preserved rather than rendered as (“blown out” to) pure black or white.
