Here are two excellent Photoshop
Tutorials from the University of Utah. These will help you
get up to speed quickly using either Photoshop CS or Photoshop 7. They
take you step-by-step through many important Photoshop features and
functionality related to editing and manipulating images and
photographs that you have downloaded from your digital camera or
scanned into your computer. These two tutorials teach
essentially the same features, use the one that is appropriate for your
version of Photoshop.

contrast makes the light areas lighter and the dark areas darker;

Exercise Two - Retouching Photos
In this exercise,
you'll use the following Photoshop features, and then proceed
to the others:
- Crop the image
-
Straighten the image
- Adjust the tonal rang
-
Removing a color cast (or imbalances of color)
-
Experiment with the various choices including the Tone
Balance.(Shadows, Midtones, Highlights)
Replacing
colors in an image
Options in the Replace Color command's
dialog box allow you to adjust the hue, saturation, and lightness
components of a selected area of the image. It helps to zoom in on the
area where you want to effect a change.
Sponge
tool - Adjusting saturation
When you change the saturation of
a color, you adjust its strength or purity. The Sponge Tool is useful
in letting you make subtle saturation changes to specific areas of an
image. We will use the sponge tool on the red and white stripped tarp
covering the main gondola in the picture.
Dodge Tool
- Adjusting lightness
Use the Dodge Tool to lighten the
highlights along the gondola's hull and exaggerate the reflection of
the water there.
Clone Stamp Tool -- Removing
unwanted objects
Use the Clone Stamp Tool to remove an object
or area by "cloning" an area of the image over the area you want to
eliminate.
Replacing part of an image
The
sky is fairly drab and overcast in this photograph. You will replace it
with a more interesting sky from another file.
