Begin with the lens blocked off and then set the lens at the smallest possible
aperture (largest f-stop number).
Make sure there is a suitable target in front of the lens. An object with text or
graphics works best.
Check the brightest regions of the image to determine if the A/D converter is at
full-scale. A 16-bit A/D is at full scale when the brightest parts of the image
reach an intensity of 65535. Adjust the aperture to where it is just slightly
smaller (higher f-stop) than the setting where maximum brightness on any part
of the image occurs.
Set the focus adjustment of the lens for maximum sharpness in the viewed
image.
