size of the image, and the file format in which you can save the
image.
For this lesson, youll create a duotone from this image. A duotone is
an image made up of screens of two basic colors, usually black and
one other ink. To do this, you must first make a Grayscale image and
then select which color to blend into the image.
A traditional black and white photograph is actually a grayscale
image to a computer. The computer uses 256 levels of gray to con-
struct the shadows and other features found in a typical black and
white image. An image in Black & White mode reduces the number
of colors in the image to two. Each pixel is either 100% black or
100% white. Therefore, the Black & White mode is not for black and
white photos, but rather for single-color illustrations, logos, or
images.
You can view the mode and resolution of a paint object by selecting
it and looking at the right end of the Status bar at the bottom of the
screen. If you select the image in this lesson youll see that it is (72
dpi) and currently in RGB Color mode.
To create a duotone
1
Select the paint object.
2
Choose Image > Mode > Grayscale.
3
Canvas asks whether you would like to discard the color infor-
mation from the image. Click OK. The image is now in grayscale
mode.
4
Choose Image > Mode > Duotone. The Duotone Options dia-
log box appears in which you define your ink colors.
5
Since only black is in the image, Canvas considers it a monotone
image. Select Duotone from the Type pop-up menu so you can
use a second color.
Tip
If you want to change the inks
used in a duotone, you must
select Image > Mode > Duo-
tone Inks. This menu item
appears when a duotone
image is selected.
