1. Introduction to the Work Area:
In this section we will look at the tools, palettes, menus and work area of Photoshop.
The Tool Palette:
To the right we have the tool palette. This contains the tools you
need for image creating, editing and manipulation. The tools with
black arrows at the bottom right corner indicate that there are more
options within that tool. To access the other tools within that tool,
just left click the mouse and hold it down. The currently selected
tool is the move tool. Hovering the cursor over the tool will give
you its name and the keyboard shortcut to access it (in the case of
the move tool Shift + M will automatically select it for you).
The tools in the top four sections of the tool palette are as follows
(moving anticlockwise):
Marquee: this tool allows you to select an area of an
image within a particular shape. The default is rectangle,
but there is also an ellipse selection as well as a single row
and single column marquee
Lasso: this tool allows you to select irregular areas of an
image. In the image to the right, the polygonal lasso tool is
showing. There is also the freehand lasso tool and the
magnetic lasso tool (which will find the edge of an
element within the image you are trying to select).
Crop: this tool allows you to cut an image to a particular
segment.
Healing Brush: this tool allows you correct imperfections,
causing them to disappear into the surrounding image. You use the healing
brush tool to paint with sampled pixels from an image or pattern. The other
Figure
tool that this button allows you to select is the patch tool. The patch tool lets
you repair a selected area with pixels from another area or a pattern.
Clone Stamp: this tool takes a sample of an image, which you can then apply
over another image or part of the same image. Each stroke of the tool paints on
more of the sample. The other tool that can be selected here is the pattern
stamp tool, which lets you paint with a pattern. You can select a pattern from
the pattern libraries or create your own patterns.
Eraser: this tool allows you to erase parts of your image. You can also select
the background eraser tool or magic eraser tool which allow you to erase
specific parts of the image.
Smudge: this tool allows you to create an effect similar to the effect caused
when working with pencils and you smudge an area of the image with your
finger. The companion tools to this tool are the blur tool and the sharpen tool
which allow you to blur the focus or sharpen the focus of an area of the image

Path Selection: used for selecting vector images. Vector images are images
that can be resized without loosing resolution because they are based on
mathematical formula as opposed to bitmapped or raster images, which are
constructed using a finite number of pixels. The companion tool to this is the
direct selection tool, which allows you select a path segment.
Pen: used for creating straight lines and smooth curves with precision. The
image created is a vector image. There are a number of companion tools to
this tool – freeform pen, add anchor point, delete anchor point and convert
point tools
Notes: this tool is used to add notes to an image. They are not part of the
image but can be useful when sharing the image as the image author can add
valuable information about the image to the image file so others can appreciate
what is intended by an image. The companion tool to this tool is the audio
annotation tool, which allows a user with a microphone attached to their
computer to add a “speaker note” to the image to convey information to other
users of the image.
Hand: allows you to move an image around the screen to allow access to
various parts of the image when the image is too big for the screen.
Zoom: allows you to magnify/de-magnify areas of an image to allow for more
detailed work
Eyedropper: this tool allows you to set the colour of the foreground of the
colour palette from a colour within the image. The companion tools are the
colour sampler tool and the measure tool, which can be used to get the exact
coordinates and pixel height and width of any part of the image
Rectangle: this tool allows you to draw different shapes,
with the default set to rectangle. You can also draw
rounded rectangles, ellipses, polygons, lines and custom
shapes.
Text: this tool allows you to add text to your image. You
can also change the orientation of text to the vertical type
tool.
Sponge: this tool allows you to subtly change the colour of
the image, by altering the colour saturation of the area
adjusted by the sponge tool. The other options under this
tool are the dodge and burn tools, which are used to
lighten or darken an area of the image respectively.
Gradient: a gradient allows you to fill an area of an image
with a colour range, where the colours gradually run into
each other. The other option with this tool is the paint
bucket or fill tool, which you would use to fill a selected
area of the image with a single colour.
History Brush: this tool allows you paint with the source
data from a specified history state or snapshot. The other
option is the art history brush which allows for painting
with stylized strokes from a specified history state or
snapshot
Paint Brush: this tool is as you would imagine used to
paint on an image. There are numerous different brush shapes and sizes that
allow the user to create different textures to their image. The other option to
this tool is the pencil tool. Slice: the slice tool allows you to divide an image into sections, making it
easier to break up the image for putting it on the web or for making composite
images. The second option under the slice tool is the slice select tool, which
allows you to apply modifications to a slice that you have created.

Magic Wand: the magic wand tool is another tool that you can use to select
an area on the screen. It is used when you want to select an area that contains
the same colour throughout.
