The move tool allows you to move a selection
or entire layer by dragging it with your mouse
or using your keyboard arrows keys. The
move tool is located at the top right of
the Photoshop Toolbox

When the move tool is selected, click and drag
anywhere in the image. By default, if an area is
selected the selection will be moved, otherwise
the whole layer will be moved.
Alternatively, use your arrow keys to move the
selection or layer in small increments. Hold down
the Shift key to move in larger increments.
Note: You can activate the move tool when
another tool is selected by holding down
the Ctrl key (Windows) or Command key (Mac
OS).

The marquee tools are selection tools which
allow you to select rectangles, ellipses and 1pixel rows and columns.
The marquee tools are located at the top left
of the Photoshop Toolbox. Click and hold
your mouse over the marquee tool to see the
four options:

7. 

Make a rectangular selection. Hold
the shift key down to constrain the selection
to a square.
Note: ImageReady also allows rounded
corners in rectangles.

8. 
Make an elliptical selection. Hold the shift key
down to constrain the selection to a circle.

Make a horizontal selection 1 pixel high.

10. 
Make a vertical selection 1 pixel wide.

11. 
The lasso selection tools (shortcut L) are
provided in three variations. The lasso tool
and polygonal lasso tool which allow you to
draw both freehand and straight edge
selections, whilst the magnetic lasso is ideal
for edges set against high contrast
backgrounds. To change from one lasso to

These tools examine the color of the image
before creating a selection.
Magic Wand Tool: This tool is great for selecting
semi-flat colors that are connecting, such as a
solid colored background.
Quick Selection Tool: When dealing with objects
that contain many colors and tones, the Quick
Selection Tool helps to grab all of those colors.
As you brush overtop of the object, Photoshop
will continuously sample the surrounding area,
and do its best to create a seamless selection.

15. 
The Crop and Slice tools are used to separate
and eventually extract or use part of the
image that is most important. Cropping takes
out everything outside your cropping area.
Slicing an image into multiple areas makes
smaller image tiles from the main image.

17. 
Crop (C): Click and drag with this tool to
create an adjustable crop area of your image.
Press Enter to crop the canvas to your
rectangular area. Press Esc to cancel the crop.
After you crop your image, part of the image
is gone; make sure that if you save over the
original image, you won’t need the content
you have cropped out

18. 
Slice (K): Used for creating web images, the
slice tool creates rectangular slices from
which you can export individual graphics.
Build web button interfaces in one canvas and
save to sliced areas for your web page.

19. 
Slice Select (K): Select your image slices and
adjust the size of the slices by moving the
handles. Hold down the Shift key to select
multiple slices at once.

20. 
The eyedropper tool lets you select a color to
make as your new foreground or background
color. If you click and hold your mouse over
the eyedropper tool, you will see that you
have five different options: Eye Dropper Tool,
Color Sampler Tool, Ruler Tool, Note Tool,
and Count Tool.

22. 
Eye Dropper Tool: Enables you to pick any color you want
as your new foreground or background color.

any image. The info window will appear with the RGB

Healing Tool, you will see a total of four
options: Spot Healing Tool, Healing Brush
Tool, Patch Tool, and Red Eye tool.

25. 

blemishes or any other imperfections from your
images.

certain area of an image with pixels from another
area.
Red Eye Tool: Enables you to remove any red eye
from your images.

Brush Tool
The brush tool is used to 'brush' color on to the
image - so I guess it is aptly named. The brush
tool also has a number of options that can be set
in the option bar.
Pencil Tool
The pencil tool works similar to the Brush tool,
but has a hard edge. Work with the pencil tool
and try the same options you did with the brush
tool - note the differences. Note that you can
adjust hardness on the Pencil, but it has no
effect.

27. 
Color Replacement Brush
This tool allows you to replace one color with the
current foreground color. For example, you have
brushed one color on the image and now think
that it was the wrong one. Instead of starting
over, you can use the color replacement brush to
correct the color. As you brush over the color, it
will leave the black and white areas alone. The
option bar for this this tool also allows you to
change the shape of the brush, not just the size
and hardness.

The Clone stamp tool is used to fix and copy
an area on an image in another place.
Pattern stamp tool is used to create a patter
copy on the image.
The shortcut key of these tools S

31. 

The history brush tool is used to undo the
previous operations you have done to your
image.
The art history brush tool helps restore the
original image and adds painterly effect.
