To straighten pictures manually, click the straighten tool in the image adjust-
ment palette and drag the cursor parallel to a line in the preview (this option can
not be used with thumbnails;
page 10). The image will be rotated by up to ±10° to
make the reference line horizontal or vertical, and the degree of rotation will be
displayed in the text box in the image adjustment window.

Image Size
Straightening does not change the dimensions of the image. Any portions of the image that do not
t in its original dimensions are cropped out, while areas that have been added to the image are
lled in black.
Unsharp Mask
Increase sharpness by making edges more
distinct. The contrast of edges is increased
while other areas are left untouched.
q
Delete: Delete the currently-selected mask
from the unsharp mask list.
w
Move Up/Move Down: Move the currently-
selected mask up or down in the unsharp
mask list.
e
Unsharp mask list: A list of unsharp masks,
identied by color channel, intensity, halo
width, and threshold (e.g., “Red, 50%, 10%,
0”). Masks apply in the order listed; to
change the order, use the up/down but-
tons.
r
Color: Choose the color channel to which
the unsharp mask applies.
t
Intensity: The amount edge contrast will be
increased.
y
Radius: The greater the radius, the wider the
edges in the sharpened image will appear.
u
Threshold: The limit at which sharpening will
be applied. If the threshold is zero, sharpening will apply to all pixels in the
image. Increasing the threshold increases the amount of contrast that must
be present between pixels before the mask will be applied, with the result
that only more distinctly contrasting edges will be aected.
