ADOBE PHOTOSHOP ELEMENTS
User Guide
Remove colorful background patterns on your 
monitor desktop. Busy or bright patterns 
surrounding a document interfere with accurate 
color perception. Set your desktop to display 
neutral grays only, using RGB values of 128. For 
more information, see the documentation for 
your operating system.

Start the Adobe Gamma utility:
In Windows, start Adobe Gamma, located in the 
Control Panels folder or in the Program 
Files/Common Files /Adobe/Calibration folder on 
your hard drive.
In Mac OS, choose Control Panels > Adobe 
Gamma from the Apple menu.

Do one of the following:
To use a version of the utility that will guide you 
through each step, select Step by Step, and click 
OK. Then, follow the instructions described in 
the utility. Start from the default profile for
your monitor if available, and enter a unique 
description name for the profile. When you are 
finished with Adobe Gamma, save the profile 
using the same description name. (If you do 
not have a default profile, contact your monitor 
manufacturer for appropriate phosphor 
specifications.)
To use a compact version of the utility with all 
the controls in one place, select Control Panel, and 
click OK. This version is recommended if you have 
experience creating color profiles.
At any time while working in the Adobe 
Gamma control panel, you can click the Wizard 
(Windows) or Assistant (Mac OS) button to switch 
to the wizard for instructions that guide you through 
the same settings as in the control panel, one option 
at a time.
Describing color
The human eye perceives color in terms of three 
characteristics—hue, saturation, and brightness 
(HSB), while computer monitors display colors by 
generating varying amounts of red, green, and 
blue (RGB) light. Photoshop Elements lets you use 
the HSB and RGB color models to select and 
manipulate color.
HSB model
Based on the human perception of color, the HSB 
model describes three fundamental characteristics 
of color: 
Hue is the color reflected from or transmitted 
through an object. It is measured as a location on 
the standard color wheel, expressed as a degree 
between 0° and 360°. In common use, hue is 
identified by the name of the color such as red, 
orange, or green.
