Duotones and other simulations
Once an image is converted to monochromes it can subsequently
be converted to a duotone in Adobe Photoshop software Despite
the "duo" prefix, duotones can actually be ones twos
three or four colors combined to make a tinted or colored monochrome
image Rich multicolor processes can be achieved with this type
of images enhancing the appearance of a simple photo.
Blue-blacks, gray-black and brown-black duotones are most popular;
tri-tones and quad-tones can be used for special effects One
of the most attractive is to create a simulated sepia-tone within
the duotone controls by building a color set of yellows magenta
and black with which the image is printed in four-color. The
ability to preview the image on-screen and adjust color and tonal
performance will enhance many projects.
