Make Backup Copy
You can automatically create a backup copy of any scan you create. To do so,
first select Auto Save After Scan (see above), then select the Make Backup
Copy checkbox.
With this checkbox selected, when you save a scan, a backup copy will be
placed in the same directory as the scanned image. Windows backup files will
have an “.sbk” extension. Macintosh backup files will have the word
“backup” after the file name.
This backup copy will be read-only, which means that you cannot make
changes to it. You can open it like a normal file, but you must save it under a
different file name before editing the image or performing analysis.
9.6.d Imaging Area Size
The imaging area is the area of the sample that is captured by the camera and
displayed in the scan window. To specify the size of your imaging area, enter
a dimension in the appropriate field. When you change one imaging area
dimension, the other will change to maintain the aspect ratio of the camera
lens.
The imaging area will change depending on your zoom factor. For example, if
you have zoomed in on a area that is 4.5 x 3.5 cm, then you would enter 4.5 for
the width (3.5 for the height would be calculated automatically).
Note: Your imaging area settings must be correct if you want to do actual-size
printing. They must also be correct if you want to compare the quantities
of objects (e.g., using the Volume Tools) in different images.
The imaging area dimensions also determine the size of the pixels in your
image (i.e., resolution). A smaller imaging area will result in a higher
resolution.
