Adobe Photoshop CS6 Top 100 Simplified Tips and Tricks by Lynette Kent

Control the colors to POSTERIZE A PHOTO (continued)
After posterizing the first photo by following all the
steps in this task, you can duplicate the steps on four
different copies of the original photo. Use different
colors for each copy and place them in a new
document to replicate the Andy Warhol–like layouts
with four posterized and juxtaposed images.
To create the second copy, open your posterized
image and click File ➪ Save As to give the copy
another name. Click the Gradient Map thumbnail in
the Layers panel to reopen the Gradient Map options
of the Properties panel. Click in the gradient to open
the Gradient Editor again. Change the colors for each
of the four color stops, always selecting the darkest
colors for the leftmost color stops and the lightest
colors for the rightmost color stops. Click OK to close
the Gradient Editor. Click File ➪ Save, saving the
second version with all the layers. Repeat this process
until you have four different versions of the image.
To finish the project, you can follow the steps in task
#33 to create a quadriptych, or just create a new
empty document and click File ➪ Place to place each
of the four images on the page.
