Example One — Dust on the Camera Sensor
If you are using a DSLR Camera and change lenses from time to time, you will eventually
discover dust on your sensor. This dust will show up as spots in your images. It will be
most noticeable in large areas that are fairly consistent in color and tone. The sky is the most
common occurrence of this effect.
The next image is a portion of the sky from a picture taken with a dirty sensor. The dust
shows as dark spots. It is not always this noticeable, but I chose this image so that you can
plainly see what it looks like.
Photoshop has a wonderful tool called a
Spot Healing Brush
. It looks like a Band-Aid and
is located on the toolbar along the left side of the Workspace.
The exact location is shown in the next image.
