Toolbox
The menu bar contains menus and submenus that allow you to use the various features of
Photoshop.
The tool options bar shows options available for the various tools.
Palettes are windows that allow quick access to some of Photoshop’s features. They can
also be accessed by going to Window on the menu bar.

The palettes are organized together with the palette groups.
The palette tab reveals the different palettes located within each group.
The toolbox contains basic tools used within Photoshop.
The status bar displays useful information about the image (magnification, file size) and
tools (brief instructions on usage).
The palettes can be minimized or maximized by clicking on the min/max button
They can be closed by clicking on the X button.
If you ever close the palettes or move them around and want to restore the default
working screen (shown in the picture), just go to Window Æ Workspace Æ Reset
palette locations.
The palettes and the toolbox can be hidden by pressing the [TAB] key. Pressing [TAB]
again will show the palettes and toolbox.
Rulers
If you want to view the image with rulers,
just go to View Æ Show Rulers [CTRL-R].
The rulers will appear on the top and left
side of the image window. Markers that
match the location of the point will also
appear. You can also create temporary
guides by clicking in the ruler and dragging
the mouse onto the image. The guides do not
appear when you print the image.

Saving Images
To save an image, go to File Æ Save As.

File Format
When saving an image, you can choose between several file formats. File format refers to the
way Photoshop saves images. Certain file formats are better suited for certain uses.
Below is a table that explains a few of the most commonly used graphics formats.
PSD
PSD is the default format for Photoshop. It saves
every piece of information from an image and is the
only format that saves layers, masks, and channels.
Photoshop saves and loads this format faster than
other formats.
PICT
PICT is the Macintosh’s graphics format. It can
support images of any size, mode, or resolution. It
is good for on-screen, multimedia presentations.
TIFF
The TIFF format is useful when you plan to transfer
images between Macintosh and IBM-compatible
computers. It allows you to save the image as either
a Macintosh or an IBM-compatible format.
BMP
The BMP format, or bitmapped image, is widely
used in Microsoft Windows applications. If you
plan to use your image in another painting
application, such as Microsoft Paint, you can save in
this format.
3
GIF
GIF is a compression format and is the most popular
method for saving images that will be used as data
transfer, such as the images found on the World
Wide Web. Grayscale, Bitmap, and Indexed Color
are the only modes that convert to GIF in
Photoshop.
JPEG
JPEG is the best format to use if you want the
highest image quality possible. You can choose
from four levels of quality. This format also
compresses the image files so that they are more
compact.
Zoom Tool
Often, the images that we edit will to too small or too large. This is where the Zoom Tool
comes in. There are many ways to use the Zoom Tool including a tool, using the mouse’s
wheel scroll, menu command, and keyboard shortcut. When the magnifying glass has a
plus sign in the center, clicking the mouse will result in zooming in. The image will be
enlarged although the actual size of the image does not change. If you press the Alt key,
the magnifying glass will have a minus sign appear. When you click in this mode, you
will zoom out of the image. You can also click, hold down, and drag the mouse to zoom
in on a certain area. Finally, pressing Ctrl-0 will result in the image automatically
resizing itself to fit the screen.
Undo and the History Palette
The undo command allows to you undo the previous action. Most mistakes you make can
be undone, so do not worry if you make an error while editing.
To access the undo, go to File Æ Undo <command>.
If you decide that you want to undo the “undo action,” there is a redo command.
This can be accessed by going to File Æ Redo <command>.
A more powerful version of Undo exists in the History Palette.
Å The history palette can be used to revert the current image
to a previous state, delete an image's states, and create a
document from a state or snapshot.
Create Document from
Current State button
Create New Snapshot
4
Just click on the different states to see different versions. If you want to create a new
image based on one of the states, just click on that state, and click on the ‘create
document from current state button.’ In order to delete a state, just select that state and
drag it to the trash can button.
The ‘create new snapshot’ button lets you create a temporary snapshot (a copy) of any
state of the image. Snapshots are similar to the states listed in the History palette, but you
can name a snapshot and can compare different snapshots easily.
Note: Snapshots are not saved with the image - closing an image deletes its snapshots.
History Brush and Art History Brush
Extra: Photoshop has two special tools called the History Brush and Art History
Brush. They will not be covered in this class, but feel free to experiment with it.
A description for both is given below.
The History Brush tool lets you paint a copy of one state or snapshot of an image
into the current image window. This tool makes a copy, or sample, of the image
and then paints with it. For example, you might make a snapshot of a change you
made with a painting tool or filter. After undoing the change to the image, you
could use the History Brush tool to apply the change selectively to areas of the
image.
The Art History Brush tool lets you paint with stylized strokes, using the source
data from a specified history state or snapshot. By experimenting with different
paint style, size, and tolerance options, you can simulate the texture of painting
with different colors and artistic styles. Like the History Brush tool, the Art
History Brush tool uses a specified history state or snapshot as the source data.
The History Brush tool, however, paints by recreating the specified source data,
while the Art History Brush tool uses that data along with the options you set to
create different colors and artistic styles.
