Step 5
Bring a standard artifact into sharp focus in the video Window’s field of view.
The Metronics calibration slide is an excellent standard to use for this proce-
dure.
Step 6
Measure the distance between 2 of the
standard’s marks on the computer
screen using a scale or ruler. Measure
as great a distance as possible.
Step 7
Calculate the measured magnification
by dividing the measured distance
(Step 6) by the actual distance shown
on the standard.
Measured magnification = Measured / Actual
Step 8
Calculate the pixel size factor by dividing the measured magnification by the
magnification value currently displayed in the right corner of the status bar.
Pixel size factor = Measured Magnification / Status bar value
Step 9
Enter the pixel size factor into the X pixel
size... field.
