Photoshop Terms and Basics
1
Introducing Photoshop • Photoshop is image editing software.
• Photoshop is the industry standard of image editing.
• An image-editing program is software that lets you
manipulate a digital image and then save it with
the changes you have made.
• Using Photoshop, you can: o Modify images in a variety of ways
o Refine colors and contrast
o Remove flaws in images
o Combine digital photographs, text, and other artwork

Digital Images • A digital image is a photograph or drawing in
electronic form o a digital image can be displayed on a computer monitor or the LCD
screen of a camera or mobile device.
• Most digital images taken with a digital camera are
jpeg files (bitmap graphics.)
• A bitmap graphic (or raster graphic) consists of
closely spaced rows of pixels, the smallest element
in a digital image.
• Resolution is the measure of pixels per inch (ppi), or
the level of detail in an image.

Starting Photoshop • When you start Photoshop for the first time, it opens
with the default workspace displayed.
• In subsequent sessions, restarting Photoshop will
display the workspace and settings that were in
effect when you exited your last session.
• The workspace includes every element of the
Photoshop program window, such as the
Document window, panels, and other elements.

The Toolbar and Panels • The Tools panel contains tools for selecting portions
of an image, adding text, adding brushstrokes,
creating vector images such as geometric shapes,
and modifying pixels in bitmap images.
• The options bar includes the controls, or options, for
the current tool.
• The Document window displays the current file.
• Panels consist of groups of related tools.
7
Using the Toolbar • The Tools panel appears on the left side of the window.
• The triangle on the lower-right corner of a tool on the
Tools panel indicates that there are additional tools,
called a tool group, hidden beneath the tool you see on
the panel.
• You select a tool on the Tools panel by clicking it with
the mouse.
• Some tools also have shortcut keys assigned.
• Many tools on the Tools panel let you modify the default
options using the options bar, which appears beneath
the Application bar in the Photoshop window.
