Back to Mac Help — Scanning

These
are basic instructions on how to scan images by using VueScan. If you require more
information or have additional questions, please examine the
"VueScan Help…" online documentation.
Before you Scan |
Configuring VueScan |

Saving Your Image
Check
to make sure that the scanner has power. The power indicator
light/power button is located on the front of the scanner and
should be green. If it is not, press the indicator light/power
button. You may also need to check to see if the power cord
has been disconnected. If you have already launched VueScan,
please quit out of the application before powering on the scanner.
NOTE:
If you are unable power on the scanner, please
notify a consultant at the service counter.
In
addition, please be aware that the "Scan to Print",
"Scan to FAX", and the "Scan to E-mail"
functions have been disabled. |
|
To
launch VueScan, open the "Apple" Menu in the upper-left
corner of the desktop. Select the "Scanner" folder, then select VueScan. (VueScan gets updated very frequently, so the exact version number will certainly be different than what's shown in the screen shots on this page.)

After
VueScan has launched, and if
the scanner is powered on and operating, you will see the correct scanner listed in the Source drop-down menu. On the right will be a pane that
displays what is on the scanner bed. On the left will be the scanner
settings and controls.
NOTE:
If you get an error when attempting to launch VueScan,
please notify a consultant at the service counter.

Once
you have selected the settings you want, click the "Preview"
button to see what
the scanned image will look like. The scanner will immediately
power up and begin to scan your document/picture. Its progress
can be monitored in the progress field along the bottom of the window.
When
completed, a preview of the scanned image created with your
chosen settings will be displayed in the Scanner Bed Pane. It
is not the final scan. If the preview image does not have the
qualities you desire, reset the settings and try again.
When
you are satisfied with the the preview image, you may need to
select the part of it you actually want for your final image.
This is especially true if the size of your original document
or picture is smaller than the size of the scanner bed or if
you have scanned more than one image at once. |

|
VueScan will automatically select the region it thinks is your document. To change this area, move the mouse pointer over the Preview picture.
Move the
pointer to the corner of the area you would like to scan,
click and hold the mouse button, then drag the crosshairs to
the opposite corner of the desired scanning area. When you release
the mouse button, there will be a moving dotted line around
what you just selected (see picture on the right). The is called
a "marquee".
If
you messed up, just click and drag elsewhere on the Preview
area, then start over with the crosshairs until you have selected
the right part of the picture. You can adjust the size of your
selected area by moving the pointer over one of the sides of the dotted rectangle, and clicking and dragging the edge of the marquee. |

|
When
you have selected the area you want to scan, click on the "Scan"
button. The scanner will power up once more and
begin to create the final scan of your image. Its progress will be tracked in the progress field along the bottom of the window. When it finishes,
the scanned image will open into a new Photoshop window. (Or another application, if you changed the Viewer in the Prefs section.)
NOTE:
The bigger your image, or the higher your chosen resolution,
the longer the scanning process will take.

If
you want to keep your final image as small a file as possible, it's
a good idea to reduce the number of colors. If file size is not
a concern, or if you want a high-quality image, then you can leave
it as is. Right now it is probably in RGB mode, which takes up a
lot more space than is necessary for an attachment or for a basic
web graphic.
In
Photoshop, open the "Image" menu at the top of the screen, then
go down to "Mode" and then to "Indexed Color..."
A
box will come up asking you how many colors you want to use.
Just click "OK" or hit the "Enter" key for the default
setting. |

|
If
you'd like to keep the image in it's higher-color (RGB) mode,
you'll need to choose the "Flatten Image" command
in the "Layer" menu in order to save it as any format
other than Photoshop's native format.
Now
you're ready to save the document. Open the "File" menu and
select "Save As..." You
should see a box similar to the one on the below. If you want
to save your image onto your flash drive, click on the pull-down menu
at the top and select your flash drive. Next, click on the
arrow button to the right of the "Save As" pull-down menu. |

|

On the far left
will be a list oou have selected your directory, its
contents will be listed in the nexf directories where you can store files. Locate your directory
in the list, and select it. Once yt column.You can also save
files to your home.utah.edu account using an FTP client like Fetch or Transmit. Click here for more information about FTP.

Now
you need to give your image a title. Click in the "Save As:"
box, and type in a new name. Then click the on the "Format"
menu and select "CompuServe GIF" (or JPEG, or whatever other
format you may want to save as). Other formats that will work
with both PCs and Macs are: TIFF, PICT, BMP, and JPEG (For more
information on various image formats please visit
Basic
Overview of Image Formats
NOTE: The JPEG format will not be an option if you
changed your image to Indexed Color.
If
you want a higher-quality picture, you should use TIFF, JPEG
(with the "Maximum Quality" option), or a PICT. The trouble
with a GIF is that it only supports 256 colors, so GIFs obviously
won't look as good as a 16-million color JPEG.
Again, if
you want a higher-color image, DON'T change the Mode to Indexed
color. |
|
Also
note that PC computers depend on a file's three-letter file extension
to determine what type of file it is (i.e. GIF, JPG, etc.). If you're
sending this picture to a person on a PC, or if you intend to put
the picture on the web, be sure to append the proper file extension
to your filename. Photoshop should do this automatically depending
on what type of format you choose.
Now
just click "Save" or hit the "Enter" key and you're basically
done. Please be aware that depending on which format you are saving
in, another window will appear before your file is saved.

You
will be asked to select the platform (Mac or PC), final image quality
(Low, Medium, High, Very High), or some form of file compression.
Just as before, you will need to base your selection on what you
plan to do with your final image. For email attachments or web graphics
you probably want lower resolution, highly compressed files. If you want high quality images, then you will probably want to choose high resolution with less compression.
