The following lists the possible rotate and flip selections:

•

 Flip/Rotate Horizontally — flips the image horizontally and

rotates it 90 degrees counter clockwise.

•

 Flip Horizontal  — flips the image horizontally.

•

 Rotate 90 CCW — rotates the image 90 degrees counter

clockwise.

•

 Rotate 90 CW — rotates the image 90 degrees clockwise.

•

 Normal — does not rotate or flip the image.

•

 Flip Vertical  — flips the image vertically.

•

 Rotate 180 — rotates the image 180 degrees clockwise.

•

 Inverts an image — changes all the dark tones in an image to

light tones, and all of the light tones to dark tones. This option
can NOT be reversed using the Edit menu Undo command.

Clicking on the image that shows the desired orientation rotates or
flips the image. Clicking the Reset button cancels the rotate or flip
action and returns the image to the original orientation.

The Astra 6450 scanner is equipped with an UTC, which gives you
the capability to scan slides and transparencies. The UTC is
optional on the Astra 6400. Negative film normally contains an
emulsion that affects the color of the image when scanned. Other
transmissive images may appear clear, but negatives often have a
muddy, brown, gray or orange tint to the image.

The VistaScan software contains a “negative” option for
compensating for the inherent color bias of the emulsions.
VistaScan is able to neutralize the cast of whichever emulsion type
is applied to the negative, based on the type of the negative.

To achieve the optimum scan from a negative:

•

 Scan negatives and slides at the highest optical resolution the

scanner supports, which is 600 dpi for this scanner. You should
also try scanning at 1200 dpi to see which resolution works best
for you.
